Document Summary
Outer layer: muscularis- smooth muscle cells, contraction, mucosa- secretory cells in lumen. Submucousa- supply of blood vessels and nerves: peritoneum- abdominal cavity connective tissue lining, covers reproductive tract, broad ligament- extension of the peritoneum lining. 3 layers: theca externa, theca interna, granulosa cell layer. Follicle involved in ovulation, causing corpus hemorrhagicum (hemorrhage) to form corpus luteum: corpus luteum degraded by prostaglandin f2 if no pregnancy, hormone produced by endometrium of uterus, oviduct, infundibulum- ovarian end, funnel shaped to catch ovulated oocytes. Contains finger-like fimbrae to catch ovulated egg: ampulla- large, thick portion. Majority of oviduct length, site of fertilization: isthmus- connected to uterus at uterotubal junction, uterus, functions. Sperm transport: control of cyclicity and luteolysis, environment for pre-attachment embryo, maternal contribution to placenta, expulsion of fetus and placenta, different types of uteri, duplex: two cervixes (rabbit, marsupial, bicornuate: uterine horns (mare, cow, dog, cat) Simplex: no uterine horns, large uterine body (primates: tissue layers.
