Moves down the oviduct uterus via beating cilia and contractions. If no fertilization 2 oocyte degenerates in oviduct. Thick, smooth muscle wall that can expand during pregnancy. Consists of connective tissue, glands, blood vessels. Cyclically thickens in preparation for a possible pregnancy. If fertilization embryo implants + develops here. If no fertilization thickened tissue is sloughed of menstruation. External genitalia that covers the external opening. Primordial germ cells (2n) formed in developing embryo. Oogonium (2n) formed during embryonic development born with. Female born with 1 oocytes in ovary. Begin meiosis meiosis is arrested at prophase i. Female is born with 1-2 million 1 oocytes. At sexual maturity only ~200k remain. 1 oocyte remains dormant until puberty (sexual maturity) Complete meiosis i and oocyte is arrested at metaphase ii.
