Document Summary

Developmental processes: cell division, cell migration, cell differentiation, cell death, hormones: androgens = male. Movement by weeks 5-6: more active fetus = more active infant. Habituation: decrease in response to continued stimuli, cha(cid:374)ge i(cid:374) sti(cid:373)uli, fetus (cid:862)respo(cid:374)ds(cid:863) Increased heart rate; different rate of sucking behaviour. By 7 months, cns develops for learning. Re: sou(cid:374)d of a (cid:373)other"s (cid:448)oi(cid:272)e; fla(cid:448)or prefere(cid:374)(cid:272)es, et(cid:272). Any environmental agents that can interfere with the process of normal development: medical drugs (ex. Thalidomide anti nausea drug in the 50-60s: maternal illness. Importance of post-natal care: why is the fetus more affected than the mother, dose effects, organogenesis (production/genesis of organs, immature liver. Pregnancy after 35: down syndrome is more common. Chemicals inhaled (nicotine and carbon monoxide) reduce oxygen. Inhaling smoke means that there is no oxygen getting to fetus. Nicotine narrows blood vessels, blood cells pick up co instead of oxygen. Difficulty conceiving: 200 mg of caffeine is the cutoff.
