Card preview (24)
The chemical regulators that are produced by ductless glands
Hormones
The study of endocrine glands and their secretions
Endocrinology
The medium which transports hormones to their target organs
Blood
The specific membrane proteins that bind hormones
Receptor
The gland that regulates adenohypophyseal secretions
Hypothalamus
The target tissues of the hormone somatotropin
All organs
The largest endocrine gland in the body
Skin
The other name for the posterior lobe of pituitary gland
Neurohypophysis
The term used for the constantly maintained internal equilibrium of the body
Homeostasis
The only hormone produced by the adenohypophysis that exhibits a positive feedback mechanism
Prolactin
Group I hormones
Lipophilic rapid initiation of chemical reaction requires intracellular receptors generally orally given if treated as drug examples are androgens and thyroxine receptor-hormone complex formation is enough to produce cellular changes
Group II hormones
requires secondary messengers transported in blood not bound to proteins examples are catecholamines and insulin
stimulates the production of beta-endorphins
CRH
stimulates production of thyroid-stimulating hormne
TRH
stimulates the production of pituitary FSH & LH
GnRH
believed as a dopamine-like inhibitor of prolactin
PIF
increases the blood levels of prolactin
PRH
otherwise known as somatocrinin
GHRH
hypothalamic secretion also referred to as somatostatin
GHIH
decreases the level of the blood MSH
MIF
directly regulates the production of aquaporins in collecting ducts
ADH
peptide hormone for milk ejection and uterine contraction
Oxytoxin
tryptophan-derived and induces sleep
Melatonin
source of urinary 5’-hydroxyindole acetic acid
Serotonin
