Cards in this set: Term GnRH Definition Before puberty, the rate of secretion of ___ from the hypothalamus are very low. Term FSH and LH Definition Before puberty, the rate of secretion of ___ and ___ from the anterior pituitary are very low. Term Progesterone Definition Decline in this hormone causes the endometrium to be sloughed and results in menses. Term Estrogen Definition Increased secretion of this hormone from developing follicles causes the endometrium to thicken during the proliferative phase. Term LH Definition A large increase in this hormone results in ovulation. Term FSH Definition At the time of ovulation this hormone acts on immature follicles and stimulates them to start developing; the follicles mature in the next menstrual cycle. Term Progesterone Definition Produced by the corpus luteum; primarily responsible for the secretory phase of the uterus. Term GnRH Definition Stimulates the secretion of FSH and LH from the anterior pituitary. Term FSH Definition Hormone that stimulates the secretion of estrogen from follicles. Term Acrosome Definition Sperm cell vesicle containing enzymes released during fertilization. Term GnRH Definition Hormone released from the hypothalamus; stimulates the anterior pituitary to secrete two hormones. Term LH Definition Released from the anterior pituitary; stimulates interstitial cells to secrete testosterone. Term FSH Definition Released from the anterior pituitary; binds to Sertoli cells and promotes sperm cell development and inhibin secretion. Term Inhibin Definition Secreted by Sertoli cells; inhibits FSH secretion. Term Testosterone Definition Before puberty, small amounts are produced by the testes and adrenal gland; inhibits GnRH, LH, and FSH secretion. Term Testosterone Definition Causes the enlargement and differentiation of the male genitalia; promotes the development of secondary sexual characteristics; necessary for spermatogenesis. Term Testosterone Definition Hormone required for normal sexual behavior.
