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.
