Document Summary
Uterine (fallopian) tubes: transports fertilized ova, extends from ovary to uterus. Vagina and external genitalia: known as vulva. Mesovarium: connects the ovary to the broad ligament. Supporting ligaments: broad ligament uterus to pelvis wall, round ligament uterus to labia majora, uterosacral ligament uterus to sacrum. Suspensory ligament: extends from the mesovarium to the body wall. Ovarian ligament: attaches the ovary to the uterus. Mesovarium: where blood vessels and nerves enter. Cortex: outer part, site for follicle development. Ovulation: release of secondary oocyte from ovary. Fertilization: sperm binds to a secondary oocyte. Oogonia: undergoes mitosis, forms a primary oocyte. Primary oocyte: starts 1st meiotic division. Starts off with many oocytes: number of oocytes decreases. Primary oocyte: finishes 1st meiotic division, forms a secondary oocyte, also forms a polar body (degenerates) Secondary oocyte: starts 2nd meiotic division. Secondary oocyte: finishes 2nd meiotic division, forms a zygote, also forms a second polar body (degenerates) Zygote reaches the uterus: 7 days after ovulation.
