Document Summary
Hormones also affect the behavior by interacting with the nervous system. Menstrual cycle = female reproductive cycle on most primate, charac by growth of the lining of the uterus, dev of corpus luteum and menstruation. Menstrual and estrous cycle are controlled by the pituitary gland and ovaries. These two interact : secretion of gonadotropins by pituitary gland. This stimulates the growth of ovarian follicles, as these mature they secrete oeastradiol, and increasing level of estradiol leads to a release of surge of lh. Lh surge causes ovulation : the ovarian follicle ruptures , relases the ovum. Under continued influence of lh, the ruptured follicle becomes a corpus luteum (yellow body), which produces estradiol and progesterone (promotes pregnancy, maitains the linign of the uterus, inhibits the production of another follicle. When enters the fallopian tube and meets a sperm , will become fertilized and attach to the uterine wall. Hormonal control of sexual behavior of lab animals.
