Prenatal development occurs in three stages: germinal, embryonic, and fetal. During the germinal stage, the fertilized egg implants in the uterus and begins cell division. In the embryonic stage, organs begin to form through organogenesis. The fetal period begins at 8 weeks when organogenesis is complete and the fetus continues growing and developing until birth. Risks during prenatal development include teratogens like alcohol, drugs, and infections from the mother. Critical periods of development include implantation and organogenesis when the fetus is most vulnerable. The birth process involves three stages of labor and delivery options like Lamaze or home birth. Assessments of the neonate include Apgar scores and routine tests are done to prevent issues.
Prenatal development occurs in three stages - the germinal stage, embryonic stage, and fetal stage. In the germinal stage from weeks 1-2, the zygote divides into cells and implants in the uterus. The embryonic stage from weeks 3-8 sees development of major organs and gender determination. The fetal stage from week 9 until birth refines organs for extrauterine life. Common issues that can impact development include genetic disorders, chromosomal abnormalities, maternal diseases, drugs/toxins, and malnutrition. Screening and some prenatal treatments exist to assess and address certain risks and conditions.
The document outlines the stages of prenatal development from conception through birth. It describes the germinal stage where the blastocyst implants and the embryonic stage where major organs begin developing. During the fetal stage, bones form and the fetus can move. The document also discusses influences on prenatal development like maternal health, nutrition, stress, and teratogens that can negatively impact the fetus.
The document summarizes prenatal development from fertilization through fetal development and birth. It describes the processes of fertilization, the embryonic period of organ development in the first 8 weeks, and fetal development in the second and third trimesters where distinctive human features form. It also discusses potential complications like congenital abnormalities, maternal factors, prematurity, and risk factors for problematic pregnancies such as existing health conditions, age, and lifestyle habits.

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.
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.
This document discusses the stages of pregnancy from conception through birth. It begins with conception and the initial germinal and embryonic stages lasting 2-8 weeks. During this time cell differentiation occurs and life support systems develop. The third and final stage is the fetal period from 9 weeks to birth, where the fetus grows substantially in size and its organ systems begin functioning. The document outlines the physical changes that occur each month and the major developmental milestones. Factors that can influence prenatal development are also examined, including maternal health, environmental toxins, infections and genetic abnormalities. Prenatal screening options like ultrasound and amniocentesis are also summarized.
The document discusses the prenatal development period from conception to birth. It is divided into three trimesters and important organs are formed. Hazards during this period like malnutrition, smoking, drinking and stress can negatively impact the fetus's development and lead to physical and psychological problems that persist after birth. Irregularities during prenatal development are often the root cause of psychological issues individuals face as adults. The prenatal period is very important as a child's future behavior is determined during this time.

Factors influencing fetal growth and developmentDEBASIS PATRO
This document defines growth and development and discusses fetal growth assessment. It defines small for gestational age (SGA) and intrauterine growth restriction (IUGR) and describes the two types of IUGR. Factors that affect fetal growth are genetic factors, sex, hormones, fetal growth factors, and placental and maternal factors. Methods for assessing fetal growth and maturity include physical examination, ultrasounds to measure fetal size and anatomy, amniotic fluid analysis to examine lung maturity, and biochemical markers in amniotic fluid and maternal serum.
Prenatal development refers to the process by which a single fertilized egg cell develops into an embryo and eventually a fetus over a period of 10 weeks. It begins with fertilization in the fallopian tubes by a sperm penetrating the egg. The zygote then divides many times over as it travels down the tube and implants in the uterus. During the first 8 weeks, most major organs and bones form as the embryo develops and the placenta, amniotic fluid and umbilical cord form to nourish the growing fetus.
This document summarizes key aspects of prenatal development from conception through birth in 3 stages: germinal, embryonic, and fetal. It discusses genetics, factors that influence development, potential complications, and the birth process. Common tests like the Apgar test are also outlined.
Prenatal development is influenced by genes and chromosomes from both parents that are passed down during conception. The zygote contains the genetic material from both the egg and sperm that will determine the traits of the developing fetus. Multiple factors can threaten healthy prenatal growth, including teratogens, the mother's health and lifestyle during pregnancy, and environmental influences. Genetics and environment both play a role in shaping development, personality, and risk of psychological disorders.
The document discusses the physical changes that occur during puberty for both boys and girls. It explains that puberty is triggered by hormonal changes which cause growth and development of secondary sex characteristics. For girls, this includes breast development, hip growth, and the start of the menstrual cycle. For boys, changes include broadening of the shoulders, deepening of the voice, growth of body and facial hair, and the start of sperm production. The document provides detailed information about the female and male reproductive systems and their functions during puberty and adolescence.
This document summarizes key aspects of human sexuality, pregnancy, and childbirth. It describes the male and female reproductive anatomy and hormones. It discusses sexual response, orientation, and health issues. It also covers fertility, pregnancy stages and care, complications, and childbirth options like natural birth and cesarean sections. The postpartum period and parenting are also briefly addressed.
Puberty is the period when children experience physical changes that turn their bodies into those capable of reproduction. Girls typically start puberty earlier than boys. During puberty, both males and females experience growth of sexual organs and body hair. Hormonal changes cause breast growth, menstruation and voice changes in females, and penis and testicle growth and wet dreams in males. Puberty is triggered by genes and hormones in the hypothalamus, pituitary gland and gonads. Taking daily showers, using deodorant and properly caring for hair, skin and teeth are important for hygiene during puberty.
This document discusses puberty and the physical changes that occur for both boys and girls. It explains that puberty is triggered by hormones around ages 10-14 when the body changes from a child to an adult. For boys, changes include growth of genitals and body hair, deepening of the voice, and production of sperm. For girls, changes involve breast development, menstrual periods that occur every 23-35 days, growth of body hair, and widening of the hips. The document provides diagrams and explanations of male and female reproductive organs and their functions during puberty and adolescence.
This document summarizes prenatal human development from fertilization through fetal development and birth. It describes the processes of fertilization, the 8-week embryonic period of rapid cell division and organ development, fetal development in the second and third trimesters including physical changes and movements, potential congenital abnormalities and their causes, maternal factors that can influence development, preterm birth, and risk factors for pregnancy complications.
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.
Puberty is the period when a child's body matures into an adult through hormone-driven changes. The pituitary gland and gonads produce hormones that stimulate growth and development during puberty. For girls, estrogen production begins around age 10-12 which causes breast development and menstrual periods. For boys, testosterone production around age 12-14 triggers growth of facial hair and deepening of the voice. Both sexes experience physical, sexual, and emotional changes as their bodies become capable of reproduction.
The document summarizes prenatal development from fertilization through the three main stages: germinal, embryonic, and fetal. It describes the key events that occur during each period such as organ formation and physical changes. It also discusses potential hazards to development like teratogens, drugs, diseases, nutrition, stress, and maternal age. The summary emphasizes educating mothers about prenatal hazards to promote a healthy pregnancy and baby.
This document provides an overview of human development from conception through adulthood. It discusses prenatal development, birth, childhood, adolescence, and aging. Key topics covered include fetal development, prenatal care, genetics, puberty, relationships, marriage, parenting, and the developmental tasks of each life stage.
Puberty is the stage of physical maturation triggered by increased secretion of hormones like Luteinizing Hormone and GnRH, resulting in sexual and somatic development. It involves breast development in females starting around age 10-14 and testicular growth in males around age 12-16. Puberty encompasses five stages of physical changes through Tanner stages including growth spurts that make individuals reproductively mature.
Prenatal development begins at conception and continues through birth. It involves three main phases - the germinal period from conception to implantation, the embryonic period from weeks 3-8, and the fetal period from week 9 until birth. During this time, a single-celled zygote develops into a fully-formed fetus through cell differentiation and growth of major organ systems. Environmental factors like maternal infections, drugs, alcohol, and toxins can negatively impact development and cause birth defects if exposure occurs during critical sensitive periods of development.
The document outlines the stages of prenatal development from conception through birth. It discusses the following stages: conception, the germinal stage (first two weeks), the embryonic stage (third through eighth weeks), and the fetal stage (ninth month to birth). Key events in each stage include fertilization, implantation, development of vital organs, bone formation, and growth to an average weight of 7.5 pounds. The document also addresses potential influences on prenatal development like maternal health, nutrition, environmental factors, and drug/alcohol exposure that can negatively impact the fetus.

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.
Puberty ( Assessment and Factor affecting puberty)DrHardik Shah
This document provides information on assessing puberty and factors that can affect the timing of puberty. It discusses evaluating puberty through measuring height, weight, sexual maturity ratings, and age of pubertal growth spurt. Genetics influence puberty timing by about 46% while environmental factors like nutrition, urbanization, chemicals like BPA, and stress can also affect the onset and progression of puberty. Chronic illness and mental health issues may delay puberty.
1) Delayed puberty is defined as the failure to start puberty by age 14 in boys and the lack of breast development by age 13 in girls.
2) Constitutional delayed puberty is the most common cause of delayed puberty in boys and girls, accounting for about 60-70% of cases. It has a genetic component and a natural history of a delayed but normal pubertal progression.
3) Other potential causes of delayed puberty include isolated gonadotropin deficiency, primary gonadal failure, functional hypogonadism due to chronic illness or excessive exercise, and rare conditions like Kallmann syndrome. A thorough history, physical exam, and testing are needed to identify the underlying cause

Human development is the study of growth and change throughout life. It includes physical, perceptual, cognitive, personality and social development. There are 8 stages from prenatal to late adulthood. Prenatal development begins with fertilization and progresses through the germinal, embryonic and fetal stages. During these stages, major organs and body systems develop and the risks of chromosomal abnormalities are highest. Genetics and environmental factors both influence prenatal development.
The age of adolescence marks a transformative phase in an individual's life, characterized by a myriad of physical, psychological, and social changes. In the context of Class 8 science, understanding these changes is vital for a holistic grasp of human development. In this article, we delve into the intricate aspects of reaching adolescence, providing examples and comprehensive study notes to facilitate a deeper comprehension.

It also provides details on each complication, such as the signs and symptoms as well as potential impacts if not properly treated. The range of complications covered illustrate how pregnancy can involve risks to both the health of the mother and developing fetus.
Physical Development of the High School Learners (Module 24)Venus Carbonel
This document discusses physical development during adolescence. It defines adolescence and outlines its three stages: early (ages 10-12), middle (ages 14-16), and late (ages 17-20). Puberty triggers physical changes like growth spurts through hormone activity. Boys and girls experience sexual maturity signs like breast growth, menstruation and wet dreams. Factors like improved nutrition have led to earlier onset of puberty. Adolescents also experience changes in sleep patterns and identity exploration. The document discusses ideal body images and nutrition needs during this critical transition to adulthood.
Sex is biologically determined by X and Y chromosomes, which trigger development of either male or female internal reproductive systems before birth. Hormones like testosterone and estrogen then influence further physical sex differentiation and sexual maturation. Studies have found correlations between higher levels of testosterone and more masculine behaviors in both males and females, such as increased aggression and preference for stereotypically male toys. Sex chromosome abnormalities can also influence physical and behavioral traits, like Klinefelter syndrome causing feminine characteristics in XY males or Turner syndrome resulting in short stature and infertility in XO females.
The reproductive system includes organs that work together for reproduction. The male and female reproductive systems have significant differences that allow for genetic material from two individuals to combine. Diseases of the reproductive system are common. The human reproductive process involves internal fertilization through sexual intercourse, where sperm fertilizes an egg inside the female's body, leading to pregnancy and birth.
The document provides an overview of physical and psychological changes that occur during adolescence, including:
- Rapid growth and development of primary and secondary sex characteristics due to increases in sex hormones.
- Differences in the timing of puberty between boys and girls, with girls starting earlier on average.
- Changes in body composition with increases in body fat and muscle.
- Brain development continuing into early twenties with improvements in cognitive abilities.
- Health risks such as obesity, eating disorders, drug and alcohol use that can arise during this transitional life stage.

The document discusses human development from conception through birth. It covers the stages of prenatal development including germinal (conception to implantation), embryonic (implantation to 8 weeks), and fetal (9 weeks to birth). Key topics include genes and DNA, meiosis and mitosis, influences of heredity and environment, risks of infertility, drugs/stress, and the stages of childbirth.
The document summarizes the stages of prenatal development from conception through the fetal stage. It describes the key events that occur each week, such as cell division, implantation, development of organ systems like the cardiovascular and digestive systems. The fetal stage involves further development and maturation of all organs until birth. Several factors that can influence prenatal development are also outlined, including the mother's health, diet, age, drug or alcohol use, mental health, exposure to diseases or environmental toxins.
The document discusses the physical and hormonal changes that occur during puberty, including growth spurts, development of primary and secondary sex characteristics, and increased hormone production. It notes that puberty transforms the body from childhood to adulthood over 3-5 years on average, but can occur between ages 8-14. While puberty involves growth, sexuality, and brain development, it can also cause problems for some adolescents like early sexual activity, teenage pregnancy, and sexually transmitted infections.
This chapter discusses puberty and biological foundations of adolescent development. It covers:
- What puberty is and its key physical and hormonal changes.
- Determinants of puberty onset like heredity, weight, hormones, and the endocrine system. Environmental factors like urban living can also influence timing.
- Growth spurts during puberty, where height increases by as much as 30% and weight gains 50%. Sexual maturation also occurs.
- Psychological impacts of puberty like changes in body image and potential social/emotional issues from early or late physical development.
- Biological foundations looking at evolution, genetics, and the interplay between heredity and environment in shaping adolescent
1. The document discusses reproduction in humans, including ante-natal care for the mother during pregnancy and care for the newborn baby. It emphasizes the importance of diet, exercise, and avoiding harmful substances during pregnancy.
2. Breastfeeding is described as important for providing nutrients and antibodies to help the baby grow and avoid infection. Other topics covered include birth control methods and some common sexually transmitted infections.
The document describes the male and female reproductive systems and their functions. It discusses the formation of reproductive organs during embryonic development and the role of hormones like testosterone. Puberty and changes in the reproductive system during this period are also outlined for both males and females. The summary discusses several key points:
1. The male reproductive organs (penis, scrotum, testes) are mostly external while the female organs (vulva, vagina, ovaries, fallopian tubes, uterus) are internal.
2. During embryonic development, reproductive structures initially develop the same but later differentiate based on hormone exposure, leading to normal development or abnormalities.
3. Puberty involves reproductive organ growth and hormonal

During middle childhood from ages 6 to 12, children experience steady physical growth and cognitive development. Physically, children gain height and weight each year, leading boys and girls to different activities. Cognitively, children develop concrete operational thinking and can reason logically about real events. Key developmental milestones include inductive and deductive logic. Children also develop learning disabilities or conditions like ADHD. Socially and personality-wise, children form peer relationships and a sense of industry, along with developing a psychological self-concept and self-esteem through social comparisons.

2. Life Stages
Life Stages:
Infancy-birth to 1 year
Early childhood- 1 to 6 years
Middle childhood- 6 to 12 years
Adolescence- 12 to 20 years
Early adulthood - 20 to 40 years
Middle adulthood- 40 to 65 years
Late adulthood- 65 years and up
3. As individuals pass through these life stages, four main type of
growth and development occur:
1. Physical: refers to body growth and includes
height and weight changes, muscle
and nerve development, and
changes in body organs.
2. Mental: refers to development of the mind
and includes learning how to solve
problems, make judgments, and deal
with situations.
4. 3. Emotional: refers to feelings and includes
dealing with love, hate, joy, fear,
excitement, and other similar
feelings.
4. Social: refers to interactions and relationships
with others
5. Forming a New Life
Fertilization (conception) – union of sperm and ovum to
produce a zygote.
Zygote – celled organism resulting from fertilization.
Dizygotic Twins (Fraternal Twins) – twins conceived by
the two union of two different ova (a single ovum that has
split) – no more alike genetically than any other siblings
and need not even be of the same sex.
Monozygotic Twins (Identical Twins) - twins resulting
from the division of a single zygote after fertilization –
genetically similar.
6. DNA, Genes and Chromosomes
Deoxyribonucleic Acid (DNA) – chemical that carries
inherited instructions for the development of all
cellular forms of life.
Genetic Code – sequence of bases within the DNA
molecule; governs the formation of proteins that
determine the structure and functions of living cells.
Chromosomes – coils of DNA that consist of genes.
7. Genes – small segments of DNA located in definite
positions on particular chromosomes; functional units of
heredity.
Human Genome – complete sequence of genes in the
human body.
Autosomes – in humans, the 22 pairs of chromosomes not
related to sexual expression.
Sex Chromosomes – pair of chromosomes that determines
sex: XX in the normal human female, XY in the normal
human male.
8. Sex Chromosome Abnormalities
Pattern/ Name Typical Characteristics Incidence Treatment
XXY Male: tall stature; tendency toward low IQ,
especially verbal.
1 in 1,000 male births No special treatment
XXX (triple X)
Female: normal appearance, menstrual
irregularities, learning disorders, mental
retardation.
1 in 1,000 female
births
Special education
XXY (kleinfelter) Male; sterility, underdeveloped secondary
sex characteristics small testes, learning
disorders.
1 in 1,000 male births Hormone therapy, special
education
XO (Turner) Female; short stature, webbed neck,
impaired spatial abilities, no menstruation,
infertility, underdeveloped sex organs,
incomplete development of secondary sex
characteristics.
1 in 1,500 to 2,500
female births Hormone therapy, special
education
Fragile X Minor-to-severe mental retardation;
symptoms, which are more severe in
males, include delayed speech and motor
development, speech impairments, and
hyperactivity: the most common inherited
form of mental retardation
1 in 1,200 male births;
1 in 2,000 female
births
Educational and behavioral
therapies when needed
9.
10. PRENATAL DEVELOPMENT
Gestation or Prenatal development – period of
development between conception and birth; the
process that transforms a zygote into a new-born.
Gestational Age – age of an unborn baby, usually dated
from the first day of an expectant mother’s last
menstrual cycle.
11. THE NEED FOR PRECONCEPTION
CARE:
Care should begin before pregnancy to identify preventable
risks.
Types of care:
Physical examination and the taking of medical and family
histories
Vaccinations for rubella and hepatitis B
Risk screening for genetic disorders and infectious diseases
such as STDs
Counseling women to avoid smoking and alcohol, maintain
a healthy body weight and take folic acid supplements
12. Symptoms of Pregnancy
Physical Change Causes and Timing
Tender, swollen breasts or
nipples
Increased production of the female hormones estrogen and
progesterone stimulates breast growth to prepare for producing
milk (most noticeable in a first preganancy).
Fatigue: need to take extra
naps
Woman’s heart is pumping harder and faster to produce extra
blood to carry nutrients to the fetus. Stepped-up production of
hormones takes extra effort. Progesterone depresses central
nervous system and may cause sleepiness. Concerns about
pregnancy may sap energy.
Slight bleeding or cramping Implantation bleeding may occur about 10 to 14 days after
fertilization when fertilized ovum attaches to lining of uterus.
Many women also have cramps (similar to menstrual cramps) as
the uterus begins to enlarge.
Food cravings Hormonal changes may alter food preferences, especially during
first trimester, when hormones have greatest impact.
13. Symptoms of Pregnancy
Physical Change Causes and Timing
Nausea with or without vomiting Rising levels of estrogen produced by
placenta and fetus cause stomach to
empty more slowly. Also, heightened
sense of smell may trigger nausea in
response to certain odors, such as coffee,
meat, dairy products, or spicy foods.
Morning Sickness may begin as early as 2
weeks after conception, but usually
around 4 to 8 weeks, and may occur at any
time of day.
Frequent urination Enlarging uterus during first trimester
exerts pressure on the bladder.
Frequent, mild headaches Increased blood circulation caused by
hormonal changes may bring these on.
14. Symptoms of Pregnancy
Physical Change Causes and Timing
Constipation Increase in progesterone may slow
digestion, so food passes more slowly
through intestinal tract.
Mood swings Flood of hormones early in pregnancy can
produce emotional highs and lows.
Faintless and dizziness Lightheaded feeling may be triggered by
blood vessel dilation and low blood
pressure or by low blood sugar.
Raised basal body temperature Basal body temperature (taken first thing in
the morning) normally rises soon after
ovulation each month and then drops
during menstruation. When menstruation
ceases, temperature remains elevated.
15. Stages of Prenatal Development
Germinal Stage – first two weeks of prenatal
development, characterized by rapid cell division,
blastocyst formation, and implantation in the wall of the
uterus.
16. Embryonic stage
Second stage of gestation (2 to 8 weeks), characterized by
rapid growth and development of major body systems and
organs.
This is a critical period, when the embryo is most
vulnerable to destructive influences in the prenatal
environment.
The most severely defective embryos usually do not
survive beyond the first trimester or 3-month period of
pregnancy.
17. Fetal stage
(8 weeks to birth)
Final stage of gestation from 8 weeks to birth, characterized
by increased differentiation of body parts and greatly
enlarged body size.
During this period, the fetus grows rapidly to about 20 times
its previous length and organs and body systems become
more complex.
Right up to birth, “finishing touches” such as fingernails,
toenails, and eyelids continue to develop.
