Mnemonic for anterior pituitary hormones:
FLAT PG
Hypothalamic hormones include:
GGGTCP
Gonadotropin releasing hormone (GnRH) works on the ___ by increasing __ and ___ secretion.
gonad, LH, FSH
Corticotropin releasing hormone (CRH) will increase ___ secretion in the cortex.
ACTH
Thyrotropin releasing hormone (TRH) increases ___ secretion in the thyroid.
TSH
Growth hormone releasing hormone (GHRH) increases __ secretion.
GH
Growth hormone inhibiting hormone (somatostatin) or GHIH/SS will decrease ___ secretion.
GH
Growth hormone has both inhibiting and stimulatory ___ hormone.
Hypothalamic
Prolactin inhibiting hormone (PIH) also known as ___ decreases ___ levels by suppressing it.
dopamine, PRL
Hormone function by moving from hypothalamus to anterior pituitary and then reach the ___ gland.
target
Neurosecretory cells in the hypothalamus generate ___ potential that stimulates the release of neurohormones.
action
A hormone needs a feedback ___ specifically ___ ones to maintain a homeostatic system.
loop, negative
Target gland hormones can suppress hormones at the ___ pituitary and hypothalamus to slow down the release of hormones. This is known as the ___ loop system.
anterior, long
The ___ loop feedback system is caused by the anterior pituitary hormone that has a feedback loop onto _____.
This is true of ___ and does not stimulate another hormone release down the path.
short, hypothalamus, prolactin
Other inputs that stimulate hypothalamus is:
ligh dark cycle
nutritional status
exercise
psychological cues
Both oxytocin and ADH are produced in the cell bodies of the ___ and are released from the nerve endings in the ___ pituitary being carried by its axons.
