Document Summary
Medulla makes up the inner cortex of the ovary; this is where you have blood supply to the ovary. The outer cortex contains the eggs developing, and you can see scars where the ovulated oocytes erupted out of the ovary. Function: generates mature germ cells in response to hormonal control signals. The endocrine gland sends signals to the uterus, hypothalamus and pituitary. Immature egg is the primary oocyte and it"s contained in a follicle. Oocyte = immature cell that may develop into an ovum by fertilization. The oocyte develops into the secondary follicle, the graafian follicle and eventually an egg comes out of the follicle. Hpo axis (hypothalamus-pituitary-ovarian): gnrh = lh, fsh = estrogen, progesterone, testosterone. Follicular phase - begins just after one gets their period. Lh and fsh are low at the start of the cycle. Low fsh stimulates hypothalamus to release more gnrh which signals anterior pituitary. Anterior pituitary releases more lh and fsh.
