Document Summary

Female reproductive system: c/c female reproductive anatomy. Female endocrinology: seq, iov female endocrinology, c/c ovarian, uterine cycles. House and nourish developing embryo, give birth. Located in abdominal cavity (as opposed to external testes) Sex hormones (cid:314) estradiol, progesterone (2) oviducts (fallopian tubes) Extend from uterus to each ovary, partially surround. Collects 2 oocyte from ovary (cid:314) carried to uterus. Oviducts cause egg movement via beating cilia and contractions. Site of embryonic development (expands during pregnancy) Myometrium (cid:314) thick outer wall of smooth muscle. Endometrium (cid:314) inner layer that lines lumen. Lines lumen (cid:314) connective tissue, glands, and blood vessels. Thickens each month in preparation for pregnancy. Fertilization (cid:314) leads to embryonic implant in uterus. No fertilization (cid:314) sloughed off (cid:314) menstruation (4) cervix. >90% of cases due to hpv (5) vagina. Mitosis of primordial germ cells (cid:314) leads to oogonia (2n) Oogonia form during development, no new oogonia after birth. Mitosis of oogonia (cid:314) leads to 1 oocyte (2n)
