Endocrine Glands Flashcards
endocrine glands
secrete hormones into the blood
target cells
cells that detect hormones
Lipid soluble hormones
attach to receptor proteins inside the cell that changes the cell
water-soluble hormones
attach to receptor proteins on surface of the cell, cause reactions in the cell
Hypothalamus
regulates pituitary hormones
secretes releasing inhibiting hormones and GnRH
Anterior pituitary
connected to the hypothalamus by blood vessels hGH TSH ACTH FSH LH Prolactin
posterior pituitary
connected to the hypothalamus by neuro-secretory glands
ADH
oxytocin
thyroid
thyroxine and calcitonin
parathyroid
PTH
adrenal cortex
cortisol
aldosterone
gonadocorticoids
adrenal medulla
epinephrine/norepinephrine
Pancreas
beta cells produce insulin
alpha cells produce glucagon
part of islets of langerhans cells
positive feedback loop
additional hormones released in response to release of hormones
oxytocin
prolactin
Tropic Hormones
released by gland to stimulate another gland to produce a hormone
releasing/inhibiting hormones
TSH, hGH, LH, FSH
