Document Summary

Conception = sperm and egg unite to bring genetic material together and form one organism (zygote). The zygote stage = first 10 to 14 days. After the nuclei of the egg and sperm fuse, the cell divides in 2, 4, 8, 16, (cid:1005)(cid:1004)(cid:1004) . Cells begin to differentiate into specialized locations and structures. At 9 weeks, hands and face have developed; the embryo is now called a fetus. At 6 months, the fetus might be able to survive outside the womb. Teratogens = (cid:894)(cid:862)(cid:373)o(cid:374)ster (cid:373)akers(cid:863)(cid:895) are su(cid:271)sta(cid:374)(cid:272)es su(cid:272)h as (cid:448)iruses a(cid:374)d (cid:272)he(cid:373)i(cid:272)als that (cid:272)an damage the developing embryo or fetus. Fetal alcohol syndrome (fas) = refers to cognitive, behavioral, and body/brain structure abnormalities caused by exposure to alcohol in the fetal stage. Fetuses in the womb can respond to sounds that they hear. Fetuses can learn to recognize and adapt to sounds that they previously heard only in the womb.
