pituitary/adrenal gland Flashcards
homeostasis
role of hormones in systemic homeostatic mechanisms
chemical classification of hormones
amine
peptide
steroid
solubility/polarity classifications of hormones
lipophilic
hydrophilic
classifications of homrones
insulin:
estrogen/androgens/cortisol:
epinephrine/norepinephrine (catechol):
thyroxine(T4) and triiodoithyrine(T3):
insulin:
hydrophilic and peptide
estrogen/androgens/cortisol:
lipophilic and steriod
epinephrine/norepinephrine:
hydrophilic and amine
thyroxine(T4) and triiodoithyrine(T3):
lipophilic and amine
catecholamines
epinephrine
norepinephrine
steroid and thyroid hormones have ____ receptors
intracellular receptors
*lipophilic
peptide and catecholamines have ____ receptors
extracellular receptors
*hydrophilic
lipophilic hormones have ____ receptors
hydrophilic hormones have ___ receptors
lipophilic hormones have intracellular receptos
hydrophilic hormones have extracellular receptors
cAMP is a ____ messenger
secondary
HPA axis
stress response
hypothalamus (CRH), pituitary (ACTH), adrenal (cortisol)
ADH is produced in the
hypothalamus
ADH is secreted by the
posterior pituitary gland
ADH causes water to
reabsorb into the blood (decrease urine volume)
four methods of hormonal communication
neurocrine
endocrine
paracrine
autocrine
neurocrine:
endocrine:
paracrine:
autocrine:
neurocrine: secretion of hormones into bloodstream by neurons
endocrine: secretion of hormones into bloodstream by endocrine glands
paracrine: hormone molecule secreted by one cell affects adjacent cells
autocrine: hormone molecule secreted by a cell affects the secretory cell
