Prenatal development occurs in three stages called trimesters. In the first trimester, the zygote undergoes cleavage and forms a blastocyst that implants in the uterine wall. The blastocyst develops extraembryonic membranes and the placenta to exchange gases and nutrients. Cells in the blastocyst differentiate into three germ layers through gastrulation, forming the basis for future tissues and organs.

Human reproduction for grade 12
Human reproduction involves the joining of an ovum and spermatozoid through fertilization to form a zygote. The female reproductive system includes ovaries that produce ova and a uterus that supports embryo development. The male reproductive system includes testes that produce spermatozoa and accessory glands. During puberty, secondary sex characteristics like breast development and facial hair emerge due to hormonal changes. Fertilization is a multi-step process where a sperm penetrates an ovum in the fallopian tube, their genetic material combines, and an embryo is formed. The embryo implants in the uterus and develops over nine months of gestation into a fetus, preparing for birth.
Ovaries.ppt
The ovaries are almond-shaped glands located on either side of the pelvis that contain follicles and the corpus luteum. The follicles secrete estrogen and the corpus luteum secretes progesterone and some estrogen. Estrogen is the primary female sex hormone and exists in three types - estradiol, estrone, and estriol. Estrogen acts on genes and is synthesized from cholesterol in the ovaries, promoting the development of female secondary sex characteristics and regulating the reproductive cycle through a feedback loop with hormones from the hypothalamus and pituitary gland.
histology of Embryology placenta
The document discusses the placenta and its classification. It can be summarized as:
1. The placenta connects the developing fetus to the uterine wall, allowing for nutrient/waste exchange between the mother and fetus through blood vessels.
2. Placentas are classified based on their shape and contact points between maternal and fetal tissues. Examples include diffuse (horses, pigs), cotyledonary (ruminants), and zonary (carnivores).
3. Placentas are also classified based on the number of tissue layers separating maternal and fetal blood. Examples include epitheliochorial (horses, pigs), endotheliochorial (carnivores), and
Twins (embryology)
Twin pregnancy occurs when a woman carries two fetuses at the same time. There are two types of twins: monozygotic (identical) twins, which develop from the splitting of a single zygote, and dizygotic (fraternal) twins, which develop from two separate eggs fertilized by two separate sperm. Monozygotic twins share the same placenta and have identical DNA, while dizygotic twins have separate placentas and are no more genetically similar than normal siblings. The document further details the development and characteristics of both types of twins.
The ovarian cycle
The menstrual cycle is governed by hormonal changes and can be divided into the ovarian cycle and uterine cycle. The ovarian cycle consists of the follicular phase where follicles mature, ovulation when an egg is released, and the luteal phase where the corpus luteum forms. The uterine cycle involves menstruation, the proliferative phase where the lining grows, and the secretory phase where the lining thickens in preparation for pregnancy under progesterone influence. These cycles allow for reproduction and are a natural part of female reproductive health.
Female reproductive system
The document summarizes key aspects of the female reproductive system, including the ovaries, oviducts, uterus, and vagina. It describes the structure and functions of the ovaries, including oogenesis and folliculogenesis. It explains how follicles develop from primordial to tertiary stages and the roles of hormones like FSH, LH, and estrogens in follicle development and ovulation. After ovulation, it describes corpus luteum formation and the roles of the corpus luteum in pregnancy or menstruation. It also briefly discusses atresia, the degeneration of ovarian follicles.
Oogenesis
Oogenesis is the process by which ova or egg cells are formed in the ovaries. It involves three main phases: 1) the multiplication phase where primordial germ cells undergo mitosis to form oogonia, 2) the growth phase where the oocytes increase in size through protein and RNA synthesis, and 3) the maturation phase where the oocytes undergo the first meiotic division to form secondary oocytes, followed by ovulation and the second meiotic division after fertilization to form the ovum. Key events include cytoplasmic growth through organelle proliferation and yolk deposition, formation of the follicle surrounding the oocyte, and reduction of the chromosome number through meiosis.
01 Gametogenesis
The document summarizes the male and female reproductive systems in humans. It describes the key organs involved in sexual reproduction, including the ovaries and testes where gametes are produced, as well as the organs involved in transport and development of eggs and sperm. It also provides details on gametogenesis, the process of forming eggs and sperm, including spermatogenesis in the testes and oogenesis in the ovaries.

Adrenal gland
The document describes the adrenal gland and its hormones. The adrenal gland has two zones - the adrenal cortex and adrenal medulla. The adrenal cortex secretes three types of hormones: mineralocorticoids, glucocorticoids, and adrenal androgens. Aldosterone is a mineralocorticoid that regulates sodium and potassium levels. Cortisol is the major glucocorticoid and helps regulate carbohydrate, protein, and fat metabolism. It also plays an important role in the body's response to stress.
ovarian cycle
The presentation discusses the ovarian cycle, which depicts the changes in the ovarian follicle during the menstrual cycle. It is comprised of the follicular phase, where follicles mature and prepare to release an egg under the influence of FSH hormones. During ovulation, a mature egg is released from the follicles into the fallopian tube. In the luteal phase, the corpus luteum forms from the remaining follicle and produces progesterone.
Ovarian and menstrual cycle
The document summarizes the female ovarian and menstrual cycle. It discusses the female reproductive organs and hormones involved in the monthly cycle. It describes the process of oogenesis where oogonia develop into oocytes in the ovaries from fetal life until ovulation. In contrast, spermatogenesis is a continual process in males where spermatogonia can produce millions of sperm daily. The cycle is regulated by levels of gonadotropins and hormones, with the corpus luteum developing after ovulation and menstruation occurring when stimulation decreases.
Powerpoint slides on Fertilization
Fertilization occurs when a sperm meets and fertilizes an egg, usually in the fallopian tubes. The fertilized egg then divides as it travels to the uterus, where it implants and receives nourishment from the mother via the placenta and umbilical cord. Over about 38 weeks, the fetus develops fully into a baby that is ready to be born.
Menstrual cycle
The menstrual cycle is normally around 28 days and has 4 phases - follicular, ovulation, luteal, and menstruation. It is regulated by the hypothalamus, pituitary gland, and ovaries. Key events include follicle development and selection during the follicular phase, ovulation triggered by the LH surge around day 14, corpus luteum formation and progesterone secretion in the luteal phase, and menstruation if implantation does not occur. The endometrium thickens and is shed each cycle in response to rising and falling estrogen and progesterone levels.
Ovulation
Ovulation occurs when a mature follicle ruptures and releases an egg. This process is controlled by the hypothalamic-pituitary-ovarian axis, where hormones like GnRH, FSH, LH, estradiol, and progesterone interact in a feedback loop. Near the midpoint of the menstrual cycle, rising estradiol triggers an LH surge which causes the follicle to rupture and the egg to be released, in a process called ovulation. If the egg is fertilized, the remaining follicle cells form the corpus luteum which produces progesterone to prepare the uterus for potential implantation.
Spermatogenesis
This ppt includes sperm formation, seminiferous tubule, anatomy of sperm, spermatogonia, spermatocytogenesis, and spermiogenesis.
Histology of male reproductive system
very well describes the different male reproductive tracts on histology aspects and their importance.
Embryology Lecture 3 spermatogenesis
Spermatogenesis is the process by which sperm cells are produced in the testes in males. It involves the transformation of spermatogonia into mature sperm through two stages: spermatocytogenesis where primordial germ cells develop into spermatids, and spermiogenesis where spermatids are transformed into mature sperm. In humans, it takes approximately 74 days to complete and produces around 300 million sperm cells daily. Oogenesis is the similar process that occurs in females within the ovaries to produce eggs.
Female reproductive system Physiology
The female reproductive system consists of ovaries, fallopian tubes, uterus, cervix, and vagina. The uterus is a pear-shaped muscular organ that supports the growing fetus during pregnancy. It undergoes dramatic growth during pregnancy through muscle cell hyperplasia and production of new muscle cells. During childbirth, powerful uterine contractions expel the fetus. The endometrium responds to ovarian hormones estrogen and progesterone in a proliferative phase where it thickens, and secretory phase where it prepares for implantation if fertilization occurs.
Mammary gland
The mammary gland develops from embryonic ectoderm layers. In humans, mammary buds form and develop into primary sprouts that become openings in the nipple called galactophores. Secondary sprouts form mammary ducts. After birth, ducts branch and elongate during puberty and pregnancy due to sex hormones. During pregnancy, alveoli and lobules form to produce milk under control of hormones like progesterone and prolactin. Colostrum is the first milk produced after birth that protects the newborn.
Implantation
The key steps in implantation are:
1. The blastocyst hatches from the zona pellucida 1-3 days after entering the uterine cavity.
2. The endometrium is prepared for implantation through the activity of hormones and growth factors.
3. Implantation begins with the blastocyst apposing and adhering to the uterine epithelium 2-4 days after entering the cavity, mediated by cytokines and adhesion molecules.
4. Trophoblastic invasion then occurs, facilitated by protein degradation of the extracellular matrix. Invasion is limited by proteinase inhibitors.
Spermatogenesis
This document summarizes the process of spermatogenesis and sperm development. It describes how sperm develop from immature forms through spermatogenesis and spermiogenesis in the testes, with support from Leydig and Sertoli cells. The document also outlines characteristics of mature semen and various factors that can influence sperm development, including hormones, temperature, diet, and environmental exposures.
Gametogenesis
Gametogenesis is the process by which haploid gametes are formed from diploid germ cells through meiosis. It occurs in the gonads (ovaries in females and testes in males) and results in the production of eggs in females through oogenesis and sperm in males through spermatogenesis. Both processes involve germ cells undergoing cell division and differentiation through meiosis to form mature haploid gametes - eggs in females and sperm in males - that can fuse during fertilization to form a new diploid organism.
Spermatogenesis (Male Reproductive System-2)
1. Spermatogenesis is the process by which sperm develop from spermatogonia in the seminiferous tubules of the testes into mature sperm over approximately 65 days.
2. During spermatogenesis, spermatogonia undergo mitosis and meiosis to become spermatocytes and then spermatids, developing into mature sperm.
3. Sertoli cells nurture and support the developing sperm cells through spermatogenesis, and Leydig cells in the testes secrete testosterone which drives spermatogenesis.
Structure of Ovum
The document summarizes the structure of an ovum or egg cell. It is round and non-motile, with a diameter of 0.15 mm in humans. Its cytoplasm is called ooplasm and its periphery contains cortical villi and granules. A vitelline membrane surrounds the plasma membrane, and a zona pellucida primary membrane surrounds that. During release from the follicle, epithelial cells attach to form the corona radiata layer.
Structure of mature ovum
The mature ovum is covered by a plasma membrane that is surrounded by protective accessory egg membranes. These membranes include a primary membrane like the vitelline membrane in many animals, which adheres closely to the plasma membrane. Secondary membranes are produced by follicle cells surrounding the ovum, and tertiary membranes are secreted by the oviduct when the egg passes to the exterior. The various egg membranes provide protection and help prevent polyspermy in mammals.
Human fertilization
The document discusses the process of fertilization in mammals like humans. It begins with the anatomy of sperm and ova. Upon contact with sperm, the ova completes meiosis to become a mature egg. The sperm undergoes capacitation to prepare for fertilization. Fertilization typically occurs in the fallopian tubes. The sperm binds to and penetrates the egg's extracellular barriers. This triggers activation of the egg and fusion of the male and female pronuclei, restoring diploidy. The zygote then undergoes cell division.
Female reproductive system
The document provides details about the female genital system, including the internal organs like the uterus, vagina, fallopian tubes, and ovaries. It describes the structure of the uterus including its layers, parts, positions, blood supply, and how it enlarges during pregnancy. It also discusses the structure of the vagina, its interior regions, relations to surrounding organs, blood supply, and supports. The summary focuses on the key internal female reproductive organs and some of their key anatomical features.
Menstrual cycle
The document summarizes the normal menstrual cycle, which typically occurs over 4 phases in a 28 day cycle. It is regulated by the hypothalamus, pituitary gland, and ovaries. The follicular phase begins with menstruation and involves follicle development and estrogen rise. Ovulation occurs around day 14 when an egg is released. In the luteal phase, the corpus luteum forms and secretes progesterone to thicken the uterine lining. If implantation does not occur, progesterone drops and menstruation begins, restarting the cycle.
Placenta
The placenta develops early in gestation to nourish the fetus and allow for the exchange of nutrients, gases, and waste between the mother and fetus. It contains branching villi that increase the surface area for exchanges without mixing the maternal and fetal blood directly. The placenta's capacity and efficiency of nutrient transfer increases over gestation through developing microvilli and upregulating transporters to meet the growing demands of the fetus. Factors like placental size, blood flow, and metabolism can influence this placental transfer of materials between the mother and developing fetus.
Pre-natal Development
This document discusses pre-natal human development from conception through birth. It describes the stages of development from the germinal period through the fetal period. During these stages, cells differentiate and life support systems develop, organs appear and growth occurs. The document also outlines various teratogens and hazards that can threaten pre-natal development, including prescription drugs, psychoactive substances, environmental toxins, maternal diseases, nutritional deficiencies, and other parental factors. Proper pre-natal care and avoiding hazards can help ensure healthy development.

During these stages, cells differentiate and life support systems develop, organs appear and growth occurs. The document also outlines various teratogens and hazards that can threaten pre-natal development, including prescription drugs, psychoactive substances, environmental toxins, maternal diseases, nutritional deficiencies, and other parental factors. Proper pre-natal care and avoiding hazards can help ensure healthy development.
Prenatal Development
The document discusses prenatal development from conception through birth. It covers key topics like the stages of prenatal development (zygotic, embryonic, fetal), how life begins through processes like ovulation, fertilization and conception. Genetic and chromosomal abnormalities are described as well as their causes and types. Environmental factors that can negatively impact prenatal development, called teratogens, are provided as examples like certain maternal diseases and drugs. The stages of prenatal development are characterized by cell differentiation and growth of major organs and body systems.
Stages of Prenatal Development
1. Prenatal development occurs in three main stages - conception, germinal (first two weeks), and embryonic (third through eighth weeks) where major organs begin to develop.
2. The fetal stage from the ninth week to birth sees continued growth and development until birth, including bone formation and ability to move.
3. Many factors can negatively influence prenatal development, including maternal health issues, nutrition, environmental toxins, drugs/alcohol, and home stressors. Proper prenatal care is important for healthy outcomes.
Prenatal Development
The document summarizes the three main stages of pre-natal development: the germinal period, embryonic period, and fetal period. The germinal period occurs within the first two weeks after conception and involves cell division and implantation in the uterus. The embryonic period lasts from weeks 2 to 8, where the zygote becomes an embryo and organs begin to form. The fetal period is from months 2 to 7, where growth and development accelerate dramatically and the fetus becomes increasingly active and developed.
Introduction to the cell
Cells have several organelles that allow them to perform essential functions for life. The nucleus contains DNA and controls the cell. The mitochondria produces ATP for energy. Plant cells also contain chloroplasts for photosynthesis, a cell wall, and a central vacuole. Other organelles include the endoplasmic reticulum for protein production, Golgi for packaging proteins, lysosomes for waste digestion, and ribosomes for protein synthesis. Together these organelles allow cells to obtain energy, make proteins, and reproduce themselves.
Reproductive system
The male and female reproductive systems both produce gametes and sex hormones, and work to transport gametes and support embryo development. The male system includes testes, ducts and glands that produce and transport sperm. The female system includes ovaries, ducts and uterus which house and nourish an embryo. Fertilization typically occurs in the fallopian tubes, and the placenta later forms to support embryo growth in the uterus. Puberty initiates the ability to reproduce, while menopause ends fertility in females.
169 Ch 29_lecture_presentation
- The document discusses human development from fertilization through the first trimester. It describes the processes of cleavage, implantation, placentation and embryogenesis that occur during this time. Cleavage involves the division of the zygote into a blastocyst through repeated cell divisions. Implantation occurs when the blastocyst attaches to the uterine wall. Placentation establishes the placenta and blood vessels around the blastocyst. Embryogenesis involves the formation of the basic structures of the embryo. The three germ layers - ectoderm, endoderm and mesoderm - are established through gastrulation.
Chapter 23 Pregnancy, Growth, and Development
The document summarizes key topics in human anatomy and physiology related to pregnancy, growth, and development. It covers fertilization and the three trimesters of pregnancy. It then discusses the prenatal periods of cleavage, embryonic development, and fetal development. Finally, it briefly outlines the postnatal periods of neonatal, infancy, childhood, adolescence, adulthood, and senescence.
Prenatal development and birth
The document summarizes prenatal development from conception through the three trimesters of pregnancy. It describes the key developmental milestones that occur each month in the first trimester such as the formation of the embryo, organs, and early movements. In the second trimester, the developing human is called a fetus and development continues with skin structures, hair growth, eye opening, and increased movement. In the third trimester, organ development is largely complete and the fetus gains weight and prepares for birth.
Retained placenta
Retained placenta is defined as failure of placental delivery within 30 minutes after birth of the baby. It occurs in about 1% of deliveries. Causes include uterine atony, a constriction ring in the uterus, or abnormal adherence of the placenta. Clinical signs include bleeding if the placenta is partially separated, a lax uterus, and examination may reveal a constriction ring or abnormal placental adherence. Management depends on the cause, and may include medications to induce uterine contractions, manual separation, or in severe cases of adherence, hysterectomy. Complications can include shock, hemorrhage, or infection.
Prenatal development from conception to birth (bsp 1-b)
The document summarizes prenatal development from conception to birth, which encompasses three main stages: the germinal stage, embryonic stage, and fetal stage. It describes the key events that occur during each stage, such as fertilization, implantation, formation of the three germ layers, and the growth and development of organs. The document also discusses potential physical, psychological, genetic, and environmental hazards to prenatal development, including maternal stress, drug use, disease, nutrition, and environmental toxins.
Prenatal stage of development
The document summarizes prenatal development in three main periods: the germinal period from conception to implantation, the period of the embryo from implantation to 8 weeks, and the period of the fetus from 9 weeks until birth. During the germinal period, the zygote develops, and in the period of the embryo, the body structures and internal organs begin to form. In the period of the fetus from 9 weeks on, the systems become functional enough for survival outside the womb starting around 22-28 weeks.
Prenatal Period
The document discusses prenatal human development from conception through the germinal, embryonic, and fetal periods. It describes the key developments that occur such as cell differentiation and organ formation. It also discusses potential teratogens or hazards to prenatal development including various drugs, environmental factors, infections, nutritional deficiencies, stress, and advanced parental age. The goal is to provide a comprehensive overview of the stages and factors that influence development before birth.
The placenta
The placenta develops from fetal and maternal tissues to function as the respiratory, nutritive, excretory, barrier and endocrine organ of pregnancy. It transfers oxygen, nutrients and waste between the mother and fetus. The placenta can develop abnormalities in its shape, size, position or adhesion to the uterine wall which may cause complications like preterm birth or hemorrhage. Placental lesions like infarcts may also occur due to conditions like hypertension.
Gestatinal trophoblastic diseases by Dr ekram
Gestational trophoblastic disease (GTD) refers to conditions arising from abnormal trophoblastic tissue that has malignant potential. Trophoblast tissue forms the fetal part of the placenta. GTD includes benign conditions like hydatidiform mole as well as malignant conditions like invasive mole, choriocarcinoma, and placental site trophoblastic tumor. Malignant GTD is staged and treated based on factors like HCG levels, tumor size, and metastatic spread. While hydatidiform mole is usually cured by suction dilation and curettage, malignant GTD may require combination chemotherapy depending on risk level. With treatment, survival rates for GTD can be high, even in metastatic cases.

1. Embryonic development involves cell division, growth, and differentiation transforming a zygote into a multicellular embryo. It includes cleavage, which creates a ball of cells from the zygote through rapid cell division without growth, and gastrulation, which sorts cells into three layers - ectoderm, endoderm, and mesoderm.
2. Human development begins with fertilization and progresses through cleavage and blastocyst formation. Implantation occurs and the embryo develops within membranes as the placenta forms to exchange nutrients and gases. Organs develop from the three germ layers through the first two trimesters.
3. Childbirth occurs in three stages - cervical dilation
pre natal development
The document discusses the stages of prenatal human development. It is divided into 3 primary stages: the germinal stage from conception to implantation, the embryonic stage from weeks 2-8, and the fetal stage from week 9 until birth. The germinal stage involves fertilization, cleavage, blastulation and implantation. The embryonic stage includes formation of the embryonic disc, gastrulation, neurulation and organogenesis as major organs begin to form.
First week of development after fertilization.pptx
1.CLEAVAGE
Cleavage consists of repeated mitotic divisions of the zygote, resulting in a rapid increase in the number of cells
[Moore et al, 2016]
At this stage, each cell is called a blastomere
Occurs as the zygote passes along the uterine tube towards the uterus
Zygote is still within the zona pellucida
Approximately 3 days after fertilization, cells of the compacted embryo divide again to form a 16-cell morula (mulberry).
2.The zygote undergoes repeated division, passing through these stages:
2-cell stage
4-cell stage
8-cell stage
16-cell stage
When there are 16 or more blastomeres, the zygote is considered a morula (a hollow ball of cells)
3.MORULA
After the zygote formation, typical mitotic division of the nucleus occurs by producing two blastomeres.
The two cell stage is reached approximately 30 hours after fertilization. Each contains equal cytoplasmic volume and chromosome numbers.
The blastomeres continue to divide by binary division through 4, 8, 16 cell stage until a cluster of cells is formed and is called morula, resembling a mulberry.
As the total volume of the cell mass is not increased and the zona pellucida remains intact, the morula
after spending about 3 days in the uterine tube enters the uterine cavity through the narrow uterine ostium (1 mm) on the 4th day in the 16-64 cell stage.
4.The transport is a slow process and is controlled by muscular contraction and movement of the cilia. The central cell of the morula is known as inner cell mass which forms the embryo proper and the peripheral cells are called outer cell mass which will form protective and nutritive membranes of the embryo.
5.BLASTULATION
● Compaction
o The blastomeres change shape and tightly align themselves against each other to form a compact ball of cells
Blastulation
The process wherein the morula is transformed into a blastula/blastocyst
A group of cells compact around the edge/periphery à will form the outer cell mass
Another group of cells group together on one side à will form the inner cell mass
A blastula/blastocyst is a ball of cells with an outer cell mass, inner cell mass, and a hollow, fluid-filled cavity
6.Blastocyst formation
4 days post-fertilization, a fluid-filled space appears-called blastocystic cavity.
fluid passes from uterus through zona pellucida to the cavity.
as fluid in cavity increases, blastomeres separate into 2 parts
thin, outer cell layer = trophoblast
inner cell mass = embryoblast
the conceptus is now called a blastocyst.
blastocysts floats in uterine cavity for about 2 days
zona pellucida degenerates,
8.As the cells become more functional, they differentiate
Outer cell mass à Trophoblast
Inner cell mass à Embryoblast
The trophoblast differentiates into two specialized layers that are important for the placenta:
Cytotrophoblast
Syncytiotrophoblast
9.The embryoblast will differentiate into a bilaminar disk, which is made up of:
Epiblast
Hypoblast

Lecture4
The document summarizes key stages of early human embryonic development, including implantation of the blastocyst, formation of the germ layers and germ disc, development of structures like the notochord and somites, and formation of the fetal membranes and placenta. It describes how the blastocyst attaches and invades the uterine wall during implantation between days 7-13, and how the germ layers of ectoderm, endoderm and mesoderm form by day 14, establishing the basic body plan of the embryo.
Embryology
During the first 3 weeks of development, the zygote undergoes cleavage to become a morula, then a blastocyst. The blastocyst implants into the uterus between days 6-7. During the second week, the amniotic cavity and yolk sac form and the bilaminar disc develops. In the third week, gastrulation occurs forming the trilaminar disc. The notochord and neural tube begin developing, marking the start of the "period of threes" where the three germ layers and other structures form. This sets the stage for organogenesis in subsequent weeks.
Embryology seminar
Embryology is the study of prenatal development to understand how anatomical structures form. The major events of the first week include conception, formation of the zygote, cleavage into blastomeres, formation of the morula and blastocyst. The blastocyst undergoes implantation in the endometrium between days 6-7. This involves apposition, adhesion, penetration and invasion. The trophoblast differentiates and the inner cell mass forms the embryo proper. During the embryonic period from weeks 4-8, the three germ layers form and all major structures and organs develop. By the end of the embryonic period at 8 weeks, the embryo has distinct human form and features.
Embroylogy
This document summarizes key stages of human embryology from fertilization through the first 3 weeks of development. It describes fertilization, where a sperm and egg fuse to form a zygote. It then discusses cleavage and blastocyst formation, implantation, and the establishment of the bilaminar and trilaminar embryos through gastrulation, forming the three germ layers of ectoderm, mesoderm and endoderm that give rise to the body's organs. Diagrams illustrate these stages of embryogenesis.

GROWTH
Growth may be defined as the normal changes in the amount of a living substance – MOYER
Growth refers to an increase in size or number – PROFFIT
Growth may be defined as a developmental increase in mass i.e, it is a process that leads to an increase in the physical size of cells, tissues, organs or organisms as a whole – STEWART 1982
“Growth signifies an increase, expansion or extension of any given tissue.” - Pinkham.(1994)
Development refers to all the naturally occurring progressive, unidirectional changes in the life of an individual from its existence as a single cell to its elaboration as a multifunctional unit terminating in death. – MOYERS 1988

prenatal growth - Dr.Hiba Abdullah Murshid
The document discusses prenatal growth and development from weeks 1 through 4. In week 1 and 2, the zygote undergoes cleavage and implants in the uterus as a blastocyst. In week 3, known as the trilaminar disk stage, gastrulation occurs as the primitive streak forms and the three germ layers - ectoderm, endoderm, and mesoderm - develop. In week 4, organ systems begin to form rapidly from the germ layers and the neural tube develops as neurulation occurs.
General embryo
The document summarizes key events during the first and second weeks of human embryonic development:
- In the first week, the fertilized egg undergoes cleavage and compaction to form a morula, which then develops into a blastocyst as it travels through the fallopian tube. The blastocyst implants in the uterine wall around day 6.
- In the second week, the blastocyst becomes fully embedded. The outer cell mass differentiates into trophoblast layers, while the inner cell mass forms the hypoblast and epiblast. Primary villi and the chorionic cavity develop as the embryo becomes established.
- By the end of the second week, the main cavities and cell layers
Embryo
The document discusses human embryology and development from fertilization through the prenatal period. It describes the major stages and events of embryogenesis including cleavage, blastocyst formation, implantation, gastrulation which establishes the three germ layers, and the formation of extraembryonic membranes and placenta. The embryonic period is outlined where the main organ systems develop by week 8. Gametogenesis and the processes of oogenesis and spermatogenesis which produce eggs and sperm are also summarized.
GENERAL EMBRYOLOGY
During the first two weeks of development, the fertilized egg undergoes cell division through cleavage to form a blastocyst. The blastocyst implants in the uterine wall and begins to develop two cell layers - the outer trophoblast and inner cell mass. The trophoblast layer further separates into cytotrophoblast and syncytiotrophoblast. The syncytiotrophoblast starts to invade the maternal tissues and establish placenta. Meanwhile, the cell mass develops into the amniotic cavity and the yolk sac to support the growing embryo. Primary villi also begin to form on the trophoblast as the basis for later placenta development.

The Nature Of Disease Controlling Disease
To control infectious disease, we must consider the origin, mode of transmission, and possible control methods. The best method is preventing spread through modifying the environment, behavioral control, treatment, and immunization. The WHO and CDC play important roles in monitoring diseases globally and investigating outbreaks.
The Nature Of Disease Controlling Disease
1. There are several methods for controlling infectious disease, including preventing transmission through behavioral changes, modifying the environment, effective sanitation practices, immunization, and using antimicrobial drugs and monoclonal antibodies.
2. The World Health Organization works to improve global health through guidance, standards, cooperation with countries, and developing health technologies.
3. The CDC investigates, monitors, and controls diseases both in the US and globally by rapidly responding to outbreaks.
The Nature Of Disease What Is Disease
The document discusses several methods for controlling infectious diseases, including preventing transmission, modifying the environment, behavioral changes, immunization, and using antimicrobial drugs and vaccines. It provides details on the different types of vaccines, how they work, and new approaches like DNA vaccines and monoclonal antibodies. The roles of organizations like the WHO and CDC in monitoring, controlling and preventing the spread of diseases globally are also summarized.
Prenatal Development
Prenatal development occurs in three stages called trimesters. In the first trimester, the zygote undergoes cleavage and forms a blastocyst that implants in the uterine wall. The blastocyst develops an inner cell mass and trophoblast layer. Gastrulation occurs as the inner cell mass forms three germ layers - endoderm, mesoderm, and ectoderm. Four extraembryonic membranes also develop - yolk sac, amnion, allantois, and chorion.
Fertilization
Fertilization typically occurs in the uterine tubes within a day of ovulation. For fertilization to happen, spermatozoa must undergo capacitation after ejaculation, which rearranges mitochondria and increases motility. A single spermatozoon penetrates the corona radiata surrounding the oocyte using enzymes, and makes contact with the oocyte to begin fertilization, causing the oocyte to complete meiosis II and form pronuclei that fuse together to prevent polyspermy.
Assisted Reproductive Technology
In vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) have allowed many previously infertile couples to have children by fertilizing eggs outside the body. However, the success rate remains around 30% so multiple attempts are often needed, increasing risks of multiple births and lower birth weights. While helping many families, assisted reproductive technologies also carry increased risks of birth defects compared to natural conception. Further research is still needed regarding their long-term safety.
Reproduction
The document summarizes the male and female reproductive systems. It describes the main organs involved in both systems, including testes, epididymis, seminal vesicles, prostate gland, penis, ovaries, uterine tubes, uterus, and vagina. It also explains key functions and processes such as spermatogenesis, the ovarian and uterine cycles, fertilization, and the hormones that regulate reproductive cycles.
