Study Notes
Prenatal Development
- Prenatal development stages: germinal, embryonic, and fetal periods with distinct characteristics and milestones.
- Germinal period (weeks 1-2): zygote formation, cell division (mitosis), and implantation in the uterine wall. Survival rate is less than 50%.
- Embryonic period (weeks 3-8): embryo development, organ formation, critical period of vulnerability to teratogens (e.g., major structural abnormalities). Survival rate is about 80%.
- Fetal period (weeks 9-40): fetus development, organ refinement, rapid brain growth. Viability is reached around 22-26 weeks.
Genetic Inheritance
- Genes: recipes for proteins, influencing cell structure and function. Humans have approximately 20,500 genes.
- Chromosomes: Normal human cells have 46 chromosomes (23 pairs).
- Autosomes: 22 pairs of similar chromosomes.
- Sex chromosomes: 1 pair determining the genetic sex (XY = male, XX = female)
- Alleles: variations of a gene. Dominant and recessive alleles determine expression of traits.
- Genotype: total genes inherited.
- Phenotype: observable characteristics.
- Genetic disorders: Cystic fibrosis and sickle cell anemia are recessive disorders impacting development; Huntington's is autosomal dominant. Frequency varies by ethnicity.
- Mutations: permanent gene changes; some are beneficial, other harmful.
Behavioral Genetics
- Behavioral genetics: interplay between genetics and environment affecting behavior.
- Nature-nurture debate: both nature and nurture influence human development in a bidirectional way.
- Genotype-environment correlations: passive (family environment influences), evocative (social reactions to temperament), and active (niche picking).
- Genotype-environment interactions: genetic predisposition influencing susceptibility to environmental factors.
- Epigenetics: heritable changes in gene expression due to environmental factors (diet, stress, teratogens).
Teratology
- Teratogens: factors causing birth defects (e.g., maternal diseases, drugs, alcohol, environmental chemicals, stress).
- Teratogen exposure during critical periods can lead to more significant damage.
- Environmental contamination/pollution/chemicals may impact fetal development.
- Timing, amount, and the individual's genetic history influences severity.
Pregnancy Complications
- Common side effects: nausea, heartburn, hemorrhoids, backache, leg cramps, etc.
- Serious pregnancy complications (require special care): ectopic pregnancy (implantation outside uterus), toxemia/preeclampsia/eclampsia, gestational diabetes, hyperemesis gravidarum, deep vein thrombosis, infections, peripartum cardiomyopathy.
Childbirth
- Stages of labor: early, active, and transition phase, leading to the birth of the baby (second stage) and delivery of the placenta (third stage).
- Interventions (Cesarean, forceps, vacuum extraction), rationale, and risks.
- Birthing options: hospital, freestanding birth centers, home births with individual and cultural considerations.
Maternal and Infant Mortality
- Maternal and infant mortality rates: substantial variations globally and within the United States, influenced by historical and sociocultural factors.
- Factors influencing rates: healthcare access, socioeconomic status, race.
Postpartum Care
- APGAR test: assesses newborn health (heart rate, respiration, muscle tone, reflex response, color) 1 and 5 minutes after birth. An APGAR score of 5 or less is cause for concern.
- Postpartum emotional states: postpartum depression vs. "baby blues."
- Neonatal Behavioral Assessment Scale (NBAS): evaluates motor development, muscle tone, and stress responses.
Alternative Paths to Parenthood
- Alternative paths to parenthood: adoption, IVF, foster care, etc., broadening family definitions.
