secreted by: interstitial cells of Leydig in testes
target: seminiferous tubules, hair follicles, glands, vocal cords, brain, male reproductive organs
function: stimulate sperm production and development of reproductive organs and male secondary
sexual characteristics that develop upon puberty onset
regulated by: LH and Inhibin
secreted by: sustentacular cells of Sertoli
target: Hypothalamus, anterior pituitary
function: inhibit release of GnRH (and thus LH and FSH) to prevent spermatogenesis
regulated by: amount of sperm stored.
Secreted by: heart
Target: kidney tubules
Function: inhibit renin release to decrease aldosterone release
Release regulated by: BP in heart.
target: AP
Function: stimulate release of ACTH
stored in: posterior pituitary (PP)
target: kidneys
function: stimulate water retention (decrease urine production) to increase blood volume and pressure
release regulated by: CRH, blood pressure
Target: adrenal cortex
Function: stimulate secretion of corticosteroids to combat stress
Secretion regulated by: CRH, negative feedback
Secreted by: Adrenal Cortex
Target: Kidney Tubules
Function: Stimualate Na+ retention to increase blood osmolarity water usually follows
Controlled: CRH, ACTH, Renin
target: AP
function: stimulate release of LH and FSH
Target: gonads
Function: stimulate secretion of testosterone, induce ovulation, stimulate secretion of estrogen and progesterone
Secretion regulated by: GnRH, negative feedback
Target: gonads
Function: stimulate egg production, sperm production
Secretion regulated by: GnRH, negative feedback
target: AP
function: Stimulate release of prolactin
target: AP
Function: inhibit release of prolactin
Secreted by: AP
Target: Mammary glands
Function: Stimulate milk production (lactation)
Regulation: PRH, low progesterone and estrogen, suckling stimulate, PIH- inhibits
secreted by: ovary, placenta
target: uterus, female reproductive tract, bones, breasts
function: stimulate oogenesis, follicle growth, repair of endometrium, growth of reproductive tract at
puberty, bone growth at puberty, increased calcium uptake from diet, breast development during
pregnancy, at puberty stimulates: increased fat deposits, hair growth, breast growth, increased
cartilage deposition
secretion regulated by: LH, FSH and Placental development will increase estrogen release
secreted by: ovary, placenta
target: uterine lining (endometrium/decidua)
function: Prepare uterus of implantation. Decrease uterine contractions. Prepare breast for lactation,
prevent oogenesis by inhibiting GNRH (and thus LH and FSH)
secretion regulated by: Placental development and corpus luteum development
secreted by: conceptus, placenta
target: corpus luteum
function: maintain corpus luteum until placenta is well formed
secretion regulated by: Placental development
secreted by: placenta
target: mammary glands, body cells, fetus
function: stimulate mammary gland development, change maternal metabolism to promote glucose
sparing, stimulate fetal growth
secretion regulated by: Placental development
secreted by: placenta
target: maternal cells
function: increase metabolism
secretion regulated by: Placental development
secreted by: placenta
target: pubic symphysis, pelvic ligaments (all fibrocartilage and ligaments are usually affected)
function: soften cartilage and ligaments to allow widening of the pelvic girdle for the birth process secretion regulated by: Placental development
secreted by: ovary, placenta
target: hypothalamus, anterior pituitary
function: inhibit GnRH (and thus LH and FSH) to prevent new follicle development and new oogenesis
secretion regulated by: estrogen levels, Placental development
