Document Summary

Know the entire process of sex determination: genes, prenatal hormonal surges, puberty hormonal surges, etc. as covered in class. Distinguish between prenatal (p. 93) vs. perinatal (p. 114). What occurs during the embryo/embryonic period, fetus/fetal period (table 4. 3), p. 94, define placenta, umbilical cord, hcg, organogenesis, ectoderm, mesoderm, endoderm. What is a critical period (p. 101), a teratogen (p. 101- See also table 4. 5 (p. 107), and table 4. 6 (p. 108). Infectious diseases: rubella, syphilis (know specific effects at specific times), hiv. Prenatal hormonal surges- testosterone, dihydrotestosterone, progesterone, estrogen, 5-alpha reductase. Puberty hormonal surges promote secondary sex characteristics and sexual feelings. Morula- early stage in development where cells are in spherical ball. Blastula/blastocyst- early stage in development where cells are in spherical ball with some diferentiation and an empty area. Blastocyst is fully embedded 11-12 days after fertilization. Embryo period: organogenesis, amnion, chorion, placenta, umbilical cord, sexual diferentiation at 7-8 weeks.
