Cards

Term
ACTH
Definition
adrenocorticotrophic Hormone
Term
where is ACTH made
Definition
adrenal hypophysis
Term
what does acth do?
Definition
stimulates the release of corticoids
Term
ADH
Definition
antidiurtic hormone/vassopressin
Term
what does vassopressin do to urine
Definition
sends it out
Term
what is adh made of?
Definition
peptides
Term
when is adh made and what does it do?
Definition
made when body is dehydrated, help body to absorb as much h20 as possible and concentrates urine.
Term
where is adh made?
Definition
neurohypophysis
Term
what type of hormone is aldosterone?
Definition
mineralocorticoid
Term
where is aldosterone made?
Definition
adrenal cortex
Term
what does aldosterone do?
Definition
stimulates Na+ reabsorption and K+ secretion in kidney...increases blood pressure
Term
what are the trophic hormones? list them, bitch.
Definition
hormones produced by hypothalamus that act on the endocrine cells in the anterior pituitary.

these are: prolactin, growth hormone, melanocyte-stimulating hormone, acth, tyhroid stimulating hormone, follicle stimulating hormone, luteinizing hormone
Term
what hormones are produced in the adrenal cortex?
Definition
aldosterone, androgens, glucocoritcoids
Term
what hormones are made in the adrenal medulla?
Definition
epinephrine, norepinephrine
Term
what's the main androgen? where are they produces?
Definition
testosterone. adrenal cortex.
Term
where is glucagon produced?
Definition
pancreas
Term
GnRH

what's it do
Definition
Gonadotrophin Releasing Hormone

tropic hormone responsible for signaling anterior pituitary endocrine cells to release luetinizing hormone and follicle stimulating hormone
Term
TRH
Definition
hypothalamus hormone that stimulates the endocrine cells in the anterior pituitary to release prolactin and TSH
Term
describe the relationship twix TSH, TRH, T3 and T4 and hypothalamus and hypophysis.
Definition
Ok. So. They hypothalamus produces TSH which is the TRH-Stimulating Hormone. The TSH goes to anterior pituitary and releases TyrosineReleasingHormone (TRH). This goes to the thyroid and releases tyrosine. Tyrosine and Iodine combine to make T3 and T4. T4 is more abundant but less "active" than T3.
Term
cRH

what's it do?
Definition
corticotrophin releasing hormone.

stimulates release of ACTH
Term
PTH

what does it do?
Definition
parathyroid hormone

causes release of Ca2+ into the blood
Term
where is glucagon produced?
Definition
pancreas
