Hormonal Control Flashcards
-what is the main controller
-what GnRH’s are released from the pituitary
-what hormones are released by the ovary
-hypothalamus and pituitary
-LH and FSH
-estrogen and progesterone
What does estrogen do (aside from helping to stimulate the endometrium)
-plays a role in what
-what are those changes (4)
-secondary sex characteristics
-reproductive organs grow
-growth spurt
-hair growth
-pelvis widens
GnRH
-produced where
-target cells
-effect on target cells
-hypothalamus
-pituitary
-stimulates release of FSH and LH
FSH
-produced where
-target cells
-effect on target cells
-pitutitary
-follicles in ovaries
-stimulates maturation of 100 follicles during the menstrual cycle and release of estrogen from them
LH
-produced where
-target cells
-effect on target cells
-pitutiarty
-mature follicle/corpus luteum
-stimulates ovulation resulting in the formation of corpus luteum, stimulates secretion of estrogen and progesterone from the luteum
Estrogen
-produced where
-target cells
-effect on target cells
-maturing follicle and corpus luteum
-endometrium and pitutitary
-stimulates thickening of endometrium, negative feedback on FSH
Progesterone
-produced where
-target cells
-effect on target cells
-corpus luteum
-endometrium, myometrium and pitutitary
-maintains endometrium, prevents contractions and works with estrogen to release negative feedback on FSH and LH (mostly LH)
