Hypothalamus Flashcards
0
Q
GHIH
A
Growth hormone-inhibiting hormone(inhibiting)
- from hypothalamus
- to anterior pituitary
- inhibits secretion of GH
1
Q
GHRH
A
Growth hormone-releasing hormone(excitatory)
- from the Hypothalamus
- to the anterior pituitary
- Action = stimulates secretion of GH
2
Q
CRH
A
corticotropin-releasing hormone(excitatory)
- from the hypothalamus
- to the anterior pituitary
- stimulates release of adrenocorticotropic hormone(ACTH)
3
Q
TRH
A
thyrotropin-releasing hormone(excitatory)
- from the hypothalamus
- to anterior pituitary
- stimulates release of thyroid-stimulating hormone(TSH)
4
Q
GnRH
A
Gonadotropin-releasing hormone(excitatory)
- from the hypothalamus
- to anterior pituitary
- stimulates release of gonadotropins(FSH and LH)
5
Q
PRH
A
Prolactin-releasing hormone(excitatory)
- from the hypothalamus
- to the anterior pituitary
- stimulates secretion of prolactin
6
Q
PIH
A
prolactin-inhibiting hormones(inhibitory)
- from the hypothalamus
- to the anterior pituitary
- inhibits secretion of prolactin
7
Q
GH
A
growth hormone
- from the anterior pituitary
- promotes growth by stimulating protein anabolism and fat mobilization
8
Q
PRL
A
prolactin
- from the anterior pituitary
- mammary glands
- promotes milk secretion
9
Q
TSH
A
thyroid stimulating hormone
- from the anterior pituitary
- to thyroid gland
- stimulates development and secretion of the thyroid gland
10
Q
ACTH
A
adrenocorticotropic hormone
- from the anterior pituitary
- to adrenal cortex
- promotes development and secretion in the adrenal cortex
11
Q
LH
A
Leuteinizing hormone
- from the anterior pituitary
- to the gonads
- female = triggers ovulation; promotes development of corpus luteum
- male = stimulates production of testosterone
12
Q
ADH
A
antidiuretic hormone
- from posterior pituitary
- to kidney
- promotes water retention by kidney tubules; raises blood pressure by stimulating muscles in walls of small arteries
13
Q
OT
A
oxytocin
- from the posterior pituitary
- to the uterus and mammary glands
- stimulates uterine contractions; stimulates ejection of milk into ducts of mammary glands
14
Q
Melatonin
A
produced by pineal gland
- production and secretion mediated largely by postganglionic retinal nerve fibers that pass through the retinohypothalamic tract to the suprchiasmatic nucleus, then to the superior cervical ganglion, and to the pineal gland
- activated by darkness and suppressed by light
