Document Summary
Ovaries: produce gametes: secondary oocytes that develop into mature ova (eggs) after fertilization. Ligmaments holding ovaries in place: broad ligament-part of parietal peritoneum. Uterine (fallopian) tubes or oviducts: -provide a route for sperm to reach an ovum. Transport secondary oocytes and fertilized ova from ovaries to uterus. Infundibulum ends in finger-like fimbriae: produces currents to sweep secondary oocyte. 3 layers: mucosa- is the ciliary conveyor belt, peg cells provide nutrition to ovum. Uterus: has fundus, body, isthmus and cervix (which opens into vagina)-know. Normal position is anteflexion-anterior and superior over bladder. Histology-3 layers-know: perimetrium (outer layer): part of visceral peritoneum, myometrium: 3 layers of smooth muscle, contractions in response to oxytocin from posterior pituitary. Has inner longitudinal muscle, middle circular and outer longitudinal muscle-different from digestive tract which only has 2 layers: endometrium: inner layer. It is highly vascularized, and has a stratum functionalis-lines cavity, sloughs off during menstruation.
