It forms 3 cell layers:
- Ectoderm: outer layer ; forms the embryos
skin and central nervous system.
- Endoderm: Inner layer; forms the digestive
lungs and tracts.
- Mesoderm: Middle layer; forms most of the

Pregnancy
The fertilized egg moves down the fallopian tube and implants in the uterus. It grows into an embryo, then a fetus. The placenta links the fetus and uterus, allowing transfer of oxygen, food and waste while keeping the blood separate. After two months, the fetus is too big for the uterus wall and connects to the placenta via the umbilical cord. The process takes about 38 weeks until birth, controlled by hormones and resulting in contractions pushing the baby out through the cervix.
Fetal Development
By the end of the first month, the embryo is about 1/10 of an inch long and the heart has begun beating. By two months, the embryo has distinct fingers and veins are visible, with the heart dividing into chambers. By three months, the fetus is fully formed at 2 1/2 to 3 inches long and organs and muscles have developed and are functioning.
The fetal development
The document summarizes fetal development from the first through ninth months of pregnancy. It describes the physical changes and growth that occurs each month, including the development of organs and limbs. By the fourth month, the fetus is about 4.3-4.6 inches long and has fingerprints on its fingers and toes. In the seventh month, the fetus weighs around 3.5 pounds and its body is well-formed. By the ninth month, the fetus is typically 18.5 inches long and weighs close to 6 pounds, with nearly fully developed lungs and brain.
Pre embryonic development
This document summarizes the stages of human gestation from conception through birth in three trimesters. The first trimester involves major organ development, as the embryo grows to about 5cm by the end of the trimester. In the second trimester, rapid growth occurs as the fetus lengthens to about 30cm and develops further. Fetal movement becomes noticeable. In the third trimester, growth continues rapidly until birth, when the average baby weighs 3kg and measures 52cm. Premature birth is defined as occurring before 37 weeks of gestation.
Human fetal development
Fetal development begins with fertilization and involves 3 key stages. First, the sperm fertilizes the egg and 3 germ layers form within 3 weeks. Next, the embryo develops further for 9 weeks. Then, membranes form to protect and nourish the embryo, including the amnion which holds fluid and the amniotic membrane. The fetus continues developing through 9 months, with rapid growth in the last trimester as organs and bones mature to prepare for birth.
First Trimester Of Pregnancy.
The document summarizes prenatal development from conception through the first trimester. It describes the key stages and events, including conception and fertilization, the germinal period where the zygote implants and begins dividing, and the embryonic period where organs and structures begin to form from the three germ layers. During this time, the developing organism is most vulnerable to environmental teratogens that can disrupt development. By the end of the first trimester, the basic structures have begun to form and the fetus is growing rapidly.
Stages of pregnancy
Pregnancy typically lasts around 40 weeks and has three stages or trimesters. In the first trimester, major organs begin to form and the placenta and umbilical cord develop to nourish the growing baby. In the second trimester, bones replace cartilage and all parts of the body mature. The third trimester is the final stage of development where the baby gains weight and the lungs mature in preparation for birth. Throughout pregnancy, the baby grows rapidly from a cluster of cells to a fully developed infant by the end of the 9 months.

Fetal development powerpoint
During weeks 14-18 of fetal development:
- The baby's body begins to catch up in size to its head, becoming more proportionate.
- Systems like hearing, breathing, and urination are maturing.
- Lanugo hair covers the baby's body. Bones are hardening and muscles developing.
- The baby practices movements and can hear outside sounds. Growth accelerates, with the baby nearly doubling in size over the next few weeks. All major developments are complete and the fetus continues growing and maturing in the womb.
Human reproduction by Maria
This document discusses the human reproductive system. It describes the primary and secondary sexual characteristics that differentiate males and females. It then explains the female reproductive system including the ovaries, uterus, Fallopian tubes, and vagina. The male reproductive system includes the testicles, vas deferens, urethra, seminal vesicles, and prostate. Fertilization occurs when an ovum and sperm join to form a zygote. Pregnancy lasts about 9 months as the embryo develops into a fetus and eventually a baby ready for birth. Labor involves three phases of dilation, expulsion, and delivery of the afterbirth.
Fetal and Placental Development (Dr.Rafi Rozan)
The document summarizes fetal development from conception through the third trimester of pregnancy. It describes the key stages and timeframes of development, including the formation of major organs in the first few months. The roles and development of the amniotic fluid, umbilical cord, and placenta are also outlined. The circulatory systems of the uterus, placenta, and fetus are explained.
Stages of gestation
The document summarizes the stages of pregnancy from conception through birth in three trimesters. It describes the key developments that occur with the fetus each week and the maternal physiological changes that take place to support the growing fetus. The major stages are conception and fertilization, formation of the three germ layers in the first few weeks, major organ development in the first trimester, bone growth and skin development in the second trimester, lung and brain maturation in the third trimester, and final preparation for birth at full-term between 37-40 weeks.
In the Womb
The document outlines the key stages of pregnancy from conception through birth in three sentences or less:
During conception, the sperm and egg unite to form a zygote which then undergoes mitosis and the first trimester involves most organ development while the mother may experience morning sickness; the second trimester brings a reduction in symptoms and viability of the fetus outside the womb increases in the third trimester along with discomfort for the mother until birth consisting of three stages of cervical dilation and delivery of the baby.
Foetal development and growth in humans
Gestation typically lasts around 40 weeks or 280 days. It involves three main periods: the ovum stage from conception to implantation around 4-5 days; the embryonic stage from implantation to 8 weeks; and the fetal stage from 8 weeks until birth. During the first month, the placenta begins functioning and the embryo's heart starts beating while it is around the size of a raisin. By the second month, most major organs have formed but are not yet fully functional, and by the third month the brain is fully formed and the fetus can feel pain while continuing to develop hair, muscles, and the ability to taste. Birth normally occurs around 38-42 weeks when the baby weighs around 7 pounds and is 20 inches long
Normal foetal development and assessment of growth final
This document summarizes normal fetal development from the first to third trimesters of pregnancy. It describes the key physical changes that occur in each week, such as implantation in week 4, formation of the neural tube in week 6, development of the brain and face in weeks 7-8, and appearance of fingernails and genitals in weeks 11-12. The second trimester sees rapid growth, eye opening, and fetal movement. In the third trimester, the fetus gains weight and body systems further mature in preparation for birth. Fetal growth is assessed using ultrasound measurements like crown-rump length to determine gestational age.
33rd-40th week of pregnancy
The baby continues developing in the 33rd-40th weeks of pregnancy. By week 40, the baby weighs around 7.5 pounds and is about 20 inches long. The baby is putting on fat stores and the lungs are finishing maturation in preparation for birth. The skull bones are still flexible to ease birth, and will fuse together after birth. Contractions and delivery can begin at any time during this period.
Fetal development
1. The document discusses fetal development from fertilization through birth, dividing it into the preovular period, embryo period, and fetal period.
2. Key events include fertilization, implantation, embryogenesis, and fetal growth through weeks of gestation.
3. Fetal circulation is described, which changes after birth when the umbilical cord is cut.
The human body and reproduction
This document describes the human reproductive system and process of reproduction from puberty through birth. It explains that during adolescence, boys and girls undergo puberty where their reproductive organs mature. It then outlines the male and female reproductive systems and their function. It details the process of fertilization where sperm and egg unite, and describes pregnancy in three trimesters. Finally, it summarizes the three stages of birth: dilation, expulsion, and delivery of the placenta.
Gestation period-class 12 biology project
- Weeks 4-6 describe the development of key early structures in the embryo including the neural tube, heart, placenta, eyes, ears, arms and legs.
- Weeks 7-9 see further development of the face, fingers, toes, genitals and other features while the embryo grows in size.
- By week 10, all vital organs have formed and the embryo is distinctly human in appearance, now termed a fetus.
The Human Body and Reprodution
The document outlines five stages of human life: infancy, childhood, adolescence, adulthood, and old age. It then provides details on the male and female reproductive systems, the processes of fertilization and pregnancy, and birth. Key points include that the testicles and ovaries produce sperm and eggs, fertilization occurs when a sperm reaches an egg in the fallopian tubes, pregnancy lasts around nine months as the embryo grows into a fetus in the uterus, and birth involves three stages of labor ending with the delivery of the baby and placenta.
Chapter 10 presentation
This document summarizes key aspects of human reproduction and gestation. It discusses the stages of gestation including early, full, and late term periods. It describes health risks associated with prematurity and going past the due date. The document outlines the three trimesters of pregnancy and details the structure and functions of the uterus. It provides information on uterine size changes during and after pregnancy. It defines menopause and notes the average age of occurrence. Finally, it lists common hormonal changes and symptoms that can happen during menopause.
pregnancy and homoeopathic management
This document provides information about pregnancy and fetal development from fertilization through the 9 months of pregnancy. It discusses the key stages of development including fertilization, cleavage, morulation, blastulation, implantation, embryogenesis, fetal growth and differentiation of organs. Each month of pregnancy is summarized, noting the physical changes and growth of the fetus. Common uterine malformations are also described briefly, along with their causes and prevalence.
Fertilization, pregnancy and birth
Fertilization occurs when a sperm meets an ovule in the fallopian tubes. During pregnancy, which lasts 9 months, the embryo is nourished through the umbilical cord and develops in the amniotic sac inside the mother's uterus. Pregnancy involves 3 stages of fetal development, and babies born before 37 weeks are considered premature. Birth happens when the amniotic sac breaks, the cervix dilates, contractions help deliver the baby, and finally the placenta is expelled.
25th-32nd week of pregnancy
The document describes the development of an unborn baby from 13.5 inches long and weighing 1.5 pounds to 17 inches long and weighing 4 pounds over the course of a pregnancy. Key developments include bones solidifying, hands becoming fully developed, sexual organs maturing, lungs developing, brain growth and ability to hear, move, taste, and learn in the third trimester. The baby gains weight and size weekly in preparation for birth.
Pregnancy and Birth
The document discusses the process of human reproduction and pregnancy. It explains that fertilization occurs when a sperm cell fertilizes an egg cell in the fallopian tubes. The zygote then travels to the uterus and develops into an embryo. By 9 weeks, the embryo has developed into a fetus, which floats in amniotic fluid and receives nutrients from the placenta until birth. Pregnancy lasts around 280 days, after which contractions begin and the baby is pushed through the birth canal head first, still connected to the mother by the umbilical cord.
Pregnancy
Pregnancy lasts approximately 280 days or 9 months and occurs in 3 stages or trimesters. It begins with fertilization of an egg by sperm in the fallopian tubes. The fertilized egg then implants in the uterus and develops into an embryo and later a fetus, receiving oxygen and nutrients from the placenta via the umbilical cord. Each trimester involves specific developmental stages for the fetus and physiological changes in the mother's body to support fetal growth. The due date is estimated based on the first day of the woman's last menstrual period.
Embrology Developmental stages of embryo
This document presents an overview of human embryology and fetal development from conception to birth in 3-sentence stages. It describes the key events from fertilization through cell division and implantation in the first few weeks. The major organ systems then develop throughout the subsequent weeks, with the fetus growing in length and weight. By week 35, the fetus is near its birth length and continues gaining fat in preparation for birth from week 36 to 40, when the fully developed fetus is ready to be delivered.
Ch18 Hum Dev
The document summarizes the key stages of human development from fertilization through birth. It describes the formation of the zygote when an egg and sperm unite, and the early cleavage and differentiation stages. It outlines fetal development by week, including the establishment of organ systems and sexual differentiation. Later stages include growth of limbs, senses and body systems. Birth occurs in three stages, starting with cervical dilation and ending with the delivery of the placenta. Risks of premature birth and preventable birth defects are also discussed.
Rb3 - Fertilization and Dev't
1. Fertilization occurs through the acrosomal reaction and fusion of the egg and sperm membranes, allowing entry of a single sperm.
2. This triggers the fast block to polyspermy within 1/10th of a second and the cortical reaction, which changes the egg cytoplasm and hardens membranes to prevent multiple fertilization.
3. Pregnancy is divided into three trimesters. The first trimester involves rapid development and differentiation of the embryo. The placenta forms and the embryo implants in the uterine wall.

3. Pregnancy is divided into three trimesters. The first trimester involves rapid development and differentiation of the embryo. The placenta forms and the embryo implants in the uterine wall.
12.fertilization pregnancy and_lactation
Fertilization occurs in the fallopian tubes. The fertilized egg implants in the uterus and develops a placenta to receive nutrients from the mother's blood. The placenta secretes hormones like HCG, estrogen, and progesterone to sustain the pregnancy. As pregnancy progresses, the placenta takes over hormonal support from the corpus luteum. Near term, estrogen levels rise and progesterone falls, preparing the body for labor and delivery of the baby.
Fertilization and Development
Internal fertilization involves the male releasing sperm into the female reproductive tract, increasing chances of fertilization. After fertilization, the zygote undergoes cleavage and develops into a morula, blastula and gastrula. The gastrula forms the three germ layers - ectoderm, endoderm and mesoderm - which give rise to the organs of animals. In humans, the blastocyst implants in the uterus and develops a placenta and umbilical cord to exchange gases and nutrients with the mother.
Presentación how babies are born by maría
Fertilization occurs when a sperm and ovule unite. Pregnancy then lasts nine months as the fertilized ovule divides and becomes an embryo, then fetus, developing limbs and organs over three trimester stages. During the first trimester the embryo forms, in the second trimester facial features develop and organs grow further, and in the third trimester the baby prepares for birth.
Lesson 4.3 Fertilization & Pregnancy
Fertilization occurs when a sperm fuses with an ovum in the Fallopian tube. Pregnancy is the development of the zygote as it travels down the Fallopian tube and implants in the uterus. The placenta then forms to nourish the growing embryo, now called a fetus. Over 40 weeks of gestation, the fetus develops fully within the amniotic sac until birth.
Methods of contraception
Family planning: is defined as "educational, comprehensive medical or social activities and services which enable individuals, including minors, to determine freely the number and spacing of their children and to select the means by which this may be achieved.
Birth control: Birth control is the use of any practices, methods, or devices to prevent pregnancy from occurring in a sexually active woman. Also referred to as family planning, pregnancy prevention, fertility control, or contraception; birth control methods are designed either to prevent fertilization of an egg or implantation of a fertilized egg in the uterus. Birth control methods may be reversible or irreversible.
Contraception: (birth control) prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation. There are different kinds of birth control that act at different points in the process.
Benefits of Family planning
Women/family
• Better health
• Less physical/emotional strain
• Improved quality of life
• Increased educational opportunities
• Increased economic opportunities
• More energy for household activities
• More energy for personal development and community activities
For Children:
• Better health
• More food and other resources available
• Greater opportunity for emotional support from parents
• Better opportunity for education
Factors that affect on the decision of using contraception:
• husband involvement
• Effectiveness--statistics show two numbers:
- Failure rate: no. of women per 100 who become pregnant after 1 yr. when using a birth control consistently & correctly
- Typical use failure rate: takes into account improper or inconsistent use
• Cost
• Ease of use
• Side effects
Family planning methods
• Hormone-based contraceptives
6 types
1) Oral contraceptives (pills)
2) Vaginal ring
3) Transdermal patch
4) Injected hormones
5) Hormonal implants
6) Hormonal IUDs
Oral contraceptives pills
Types of Contraceptives Pills
Combined oral contraceptives (COCs)
Most widely used
Contain both estrogen & progestagen
Triphasic pill
Levels of hormones (estrogen & progestin) fluctuate during cycle
Progestin-only pills (POPs)
Contain only a progestagen, mostly Levonorgestrel (no estrogen).
Especially suitable for breastfeeding women.

fertilization
The document discusses the process of fertilization in several species. It describes 5 steps for recognition and fusion of egg and sperm cells, including chemoattraction, release of acrosomal enzymes, binding to extracellular envelopes, passage through envelopes, and fusion of nuclei. It also discusses the acrosome reaction, prevention of polyspermy through changes in electric potential and cortical granule reaction, and activation of the egg through calcium signaling and increased metabolism. Finally, it summarizes the process of sperm capacitation required for fertilization competence.
Menestrual cycle, fertilization & implantation
This document summarizes the female menstrual cycle and processes of fertilization and implantation. It describes the hormonal interactions between the hypothalamus, pituitary gland, ovaries and uterus that regulate the monthly menstrual cycle. It explains follicular development, ovulation, formation of the corpus luteum, and the endometrial changes regulated by estrogen and progesterone in preparation for potential implantation. The processes of fertilization, cleavage, morula and blastocyst formation are outlined. Implantation of the blastocyst in the uterine wall typically occurs 6-7 days post fertilization.
fertilization and pregnancy 1
1) Fertilization occurs when a sperm penetrates an egg in the fallopian tube, forming a zygote. The zygote then undergoes cell division as it travels to the uterus.
2) Implantation begins around 7 days after fertilization, when the blastocyst attaches to the uterine wall and burrows into the endometrium using enzymes.
3) Successful implantation establishes communication between the developing embryo and the mother's blood supply in the endometrium. This allows for nutrient exchange and marks the beginning of pregnancy.
Human fertilization
The document discusses the process of fertilization and early human development. It describes the stages of coitus and sperm transfer, the contact of sperm and oocyte in the uterine tube, nuclear fusion during fertilization, and cleavage in the uterine tube. It further explains that implantation occurs around 6-7 days after fertilization, where the trophoblast forms the placenta and the inner cell mass forms the embryo.
Human fertilization
This document discusses oocyte maturation and the processes involved in fertilization. It begins with an overview of nuclear and cytoplasmic maturation during oocyte development. It then describes the structures and organelles involved in cytoplasmic maturation, including redistribution of mitochondria, endoplasmic reticulum, cortical granules, and lipid droplets. The document next explains the capacitation of sperm in the female reproductive tract. It discusses the molecular changes involved in capacitation and the associated increases in motility. The document concludes by outlining the steps of fertilization, including sperm penetration of the zona pellucida and associated acrosome reaction, binding and fusion of sperm with the oocyte membrane.
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.
Family Planning
The document discusses various methods of family planning, including natural and artificial methods. Natural family planning relies on abstinence from sex during the most fertile times in a woman's cycle, which can be determined through basal body temperature tracking, cervical mucus monitoring, or calendar-based cycle tracking. Artificial methods prevent pregnancy through contraceptives like birth control pills, IUDs, condoms, diaphragms, spermicides, sterilization procedures (vasectomy for men or tubal ligation for women), or hormonal injections. Withdrawal is also mentioned as a method where the man removes his penis from the vagina before ejaculation.
Embryonic Development
The document discusses embryonic development in humans. It begins with fertilization and cleavage, followed by gastrulation where the three germ layers are formed. During this time the primitive streak and Henson's node develop. Organogenesis then occurs, forming individual organs from the germ layers. Mammalian development includes the allantois and notochord. In humans, the placenta forms and gestation occurs over three trimesters, with major organ structures present by the first trimester.
Stages of fetal growth and development
The growth and development of the fetus is typically divided into three stages: the preembryonic stage from fertilization to 2-3 weeks, the embryonic stage from 4-8 weeks, and the fetal stage from 9 weeks until birth. During each stage, the fetus develops organ systems and physical features according to a general timeline, growing from a fertilized egg to a fully-formed baby by the end of the 38 week gestational period.

Prenatal Development by Trimester
First trimester: Fertilization occurs when an egg and sperm unite to form a zygote with 46 chromosomes. The zygote implants in the uterus and begins rapidly dividing, forming an embryo and placenta. The embryo's brain, heart and organs begin developing from three germ layers. By the end of the first trimester, the neural tube has closed and basic facial features are appearing.
Second trimester: The baby's skeleton develops bones while its lungs, nervous system and other organs continue maturing. External sex becomes apparent and body hair grows.
Third trimester: The baby's bones are fully formed though still soft. Its central nervous system controls body temperature and limbs grow chub

fetal development and fetal circulation
This document discusses fetal development from implantation through the three trimesters and summarizes key changes that occur each week. It also describes the major fetal organs and their development. Regarding fetal circulation, it notes that the placenta provides oxygen to the fetus while the lungs receive little blood and do not exchange gas. The umbilical vein and arteries as well as ductus venosus, foramen ovale, and ductus arteriosus allow blood to bypass the lungs and circulate from the placenta to the fetal heart and body before birth.
Fetus GROWTH AND ITS INFLUENCE ON DRUGS
The document discusses fetal growth and development and how drugs can influence it. It describes the typical stages of fetal growth from the pre-embryonic stage through the fetal stage. Key aspects of growth are covered for each trimester of pregnancy. Factors that can affect fetal growth like genetics, maternal health, nutrition, and drug use are examined. The risks of drugs passing from the mother to the fetus are summarized, including potential direct harm to the fetus or indirect issues from reduced blood flow or oxygen. Strict evaluation of drug safety during pregnancy is needed given limited research.
Fetal/Embryonic development in 3 trimester
This document summarizes the stages of human embryo and fetal development from conception through birth. It is divided into three sections: embryo development, fetal development by trimester, and specific weeks of development. The key stages of embryo development include fertilization, cleavage, gastrulation and cellular differentiation. Fetal development is broken down by the three trimesters, with the first establishing organs and the second focusing on growth and the third preparing for birth. Each week of development outlines the changes, growth and milestones occurring with the fetus.
Fetal development
1. Fetal development occurs in three main stages - the pre-embryonic period from weeks 1-2 where rapid cell multiplication occurs, the embryonic period from weeks 3-8 where major organ systems develop, and the fetal period from weeks 9 until birth where the fetus continues to grow and develop.
2. During the pre-embryonic period the zygote travels through the fallopian tube and undergoes cell division, and in the embryonic period the major organs begin to form.
3. In the fetal period from months 3-9 the fetus continues to develop and grow, with all essential external and internal structures present by the end of the embryonic period, and the fetus gaining weight and length throughout
FOETAL DEVELOPMENT - OUTLINE
This document outlines the key stages of fetal development from conception to birth. It describes the processes of conception, fertilization and implantation that occur in the first 4 weeks. The major developmental changes that happen in each trimester are then outlined, including the formation of major organs in the first trimester, rapid growth and development in the second trimester, and further physical maturation in the third trimester as the fetus prepares for birth. Factors that can influence normal fetal growth rates are also briefly discussed.
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.
Prenatal development.ppt
During prenatal development, a single fertilized egg undergoes cell division and differentiation over approximately 38 weeks to become a full-term baby. It progresses through three primary stages - the germinal stage from conception to implantation, the embryonic stage from weeks 1-8 where major organs and structures form, and the fetal stage from weeks 9-38 where growth and maturation occur. By week 8, all essential external and internal structures have developed to mark the transition from embryo to fetus.

Development of the Baby
During the first trimester of development, the baby's major organs and body structures begin to form through the process of gastrulation. By the end of the trimester, the fetus is about 3cm long and can move its limbs and turn its head. In the second trimester, the baby grows to about 25cm long and half a kilogram by the end. Its face is fully formed and the mother can feel it kicking. In the final trimester, the baby is nearly ready to be born, weighing around a pound and measuring 10 inches long. Mothers experience strong emotions as delivery approaches around weeks 40-42.
humanembryonicdevelopment-141015070629-conversion-gate02 (1).pdf
The stages of pregnancy and development include fertilization, embryonic development, fetal growth and development, and childbirth. Key events include zygote formation within a few days of conception, implantation in the uterus around 1 week, and formation of the three primary germ layers and development of organ systems by 8 weeks. The fetus continues to grow and differentiate over the next 5 months, nearly doubling in size each month. Birth occurs around 9 months after internal and external changes prepare the fetus for life outside the womb.
Lesson6.3
The document summarizes key stages of fetal development from weeks 1 through 12 of gestation. During this time, major organs and structures form, including the heart, brain, eyes, limbs, and fingerprints. By week 12, all basic structures are developed, though continuing growth and development will occur. It also defines key terms like gestation period, umbilical cord, amniotic sac, and types of abortion.

EMBRYOLOGY FINAL.pdf
The document provides an overview of human embryology and fetal development from conception through 38 weeks. It defines key terms and explains the important processes that occur each week. In the first 8 weeks (embryonic period), organs begin to form through organogenesis. From weeks 9-38 (fetal period), the fetus continues to grow and develop until birth. Key events include implantation, formation of germ layers and organs, bone ossification, and physical changes that result in a recognizable human form.
Foetal development and growth in humans
Gestation typically lasts around 40 weeks or 280 days. It involves three main periods: the ovum stage from conception to implantation around 4-5 days; the embryonic stage from implantation to 8 weeks; and the fetal stage from 8 weeks until birth. During the first month, the placenta begins functioning and the embryo's heart starts beating while it is around the size of a raisin. By the second month, most major organs have formed but are not yet fully functional, and by the third month the brain is fully formed and the fetus can feel pain while continuing to develop hair, muscles, and the ability to taste. Birth normally occurs around 38-42 weeks when the baby weighs around 7 pounds and is 20 inches long
Beyond fertilization
This document summarizes the key stages of human development from fertilization through pregnancy. It describes the processes of cleavage, morphogenesis, differentiation and growth that occur during embryogenesis. The stages of development from morula to blastocyst to embryonic disk are outlined. During the trimesters of pregnancy, the placenta forms and the embryo embeds in the uterus while organs and limbs develop. Fetal circulation and extraembryonic membranes such as the chorion, amnion and yolk sac are discussed. The document concludes with a description of parturition and birth.
ppt on FETAL DEVELOPMENT class 12 in depth.pptx
This document discusses fetal development from conception through the three trimesters of pregnancy. It begins with definitions of fetus and outlines the germinal and embryonic stages when the fetus forms. It then describes the development that occurs in each of the three trimesters, including physical changes and growth. The document also discusses nutrition needs for the mother and fetus as well as potential pregnancy complications.
Gestation process
The document discusses the development of an embryo from conception through the first trimester of pregnancy. It notes that an embryo becomes known as a fetus after the first three months. A placenta forms, allowing the fetus to receive nutrients and oxygen from the mother while removing waste. Key developmental milestones are outlined, such as the appearance of the neural tube, somites, and early structures of the heart and other organs. Childbirth consists of three phases: dilation of the cervix, delivery of the baby, and delivery of the placenta. A C-section may be performed if normal vaginal birth poses risks.

- 1. Alexandria Marcellus & Yesica Galvan P.5 Human Development – Fertilization to birth
- 2. First Trimester :] ( 1-3 months ) • Gastrulation Happens after about 3 weeks from fertilization. It forms 3 cell layers: - Ectoderm: outer layer ; forms the embryos skin and central nervous system. - Endoderm: Inner layer; forms the digestive lungs and tracts. - Mesoderm: Middle layer; forms most of the other organs
- 3. Second Trimester ( 3-6 months ) • The fetus gets to about 25 cm. • And by the end of the trimester it will reach about 0.5 kg • This is the time where you get to visualize the offspring’s face with complete eyelashes and eyebrows . • Also the heartbeat becomes easier to detect • This is when the mother starts to feel activity in the belly because the baby is taking up space and forming in what is called the ‘’fetal position’’
- 4. Third Trimester ( 7- 9 months ) • The fetus will begin to experience rapid growth. • The babys body is getting ready and preparing itself to breathe air and preform other actions outside of the moms fetus. • As this happens, it fills more and more of the fetus, less action is taking place.
- 5. Its time to have the baby! ( Child birth) • One average a baby is 40-50 cm long and weighs about 7-12 pounds. • A signal to know the baby is ready to come out the mother will start to experience contractions which only get stronger and throughout the process. ( labor ) • Oxytocin: Cells that form in muscles of the uterus that serve as receptors.
- 6. What does the baby look like after birth? • The color of the infant most of the time is a blueish color and is covered with blood and mucus. Not a very pleasing sight. • Not to mention the facial features are distorted from being forced out of the vagina. • But luckily these distortions disappear within hours after birth but of course the baby was beautiful to its parents before it was even born :]
- 7. Thank you for watching! :] & to prevent this process. USE PROTECTION.
