histology - cell secretions Flashcards
Where are somatotropic cells found and what do they secrete?
anterior pituitary
GH
Where are thyrotropic cells found and what do they secrete?
anterior pituitary
TSH (regulates thyroid secretion)
Where are corticotropic cells found and what do they secrete?
anterior pituitary
ACTH (stimulates adrenal cortex to secrete stress-related hormones, mediate metabolism)
MSH (stimulates melanocytes)
Where are gonadotropic cells found and what do they secrete?
anterior pituitary
FSH and LH
Where are mammotropic cells found and what do they secrete?
anterior pituitary
prolactin (stimulates milk production)
What two hormones are synthesized by the pineal gland?
melatonin and serotonin
Where are C cells found and what do they secrete?
just outside follicles of the thyroid
secrete calcitonin
Where are chief/principle cells found and what do they secrete?
in the parathyroid gland
PTH
What is secreted from the zona glomerulosa of the adrenal cortex and what is the general function of the secretion?
mineralcorticoids (influence Na and K levels)
aldosterone
What is secreted from the zona fasciculata of the adrenal cortex and what is the general function of the secretion?
glucocorticoids (respond to ACTH to influence glucose metabolism
cortisol
What is secreted from the zona reticularis of the adrenal cortex and what is the general function of the secretion?
androgens (influence secondary sex characteristics
Where are chromaffin cells found and what do they secrete?
adrenal medulla
secrete epinephrine or NE in response to SNS
Where are alpha cells found and what do they secrete?
endocrine pancreas
glucagon
Where are beta cells found and what do they secrete?
endocrine pancreas
insulin
Where are delta cells found and what do they secrete?
endocrine pancreas
somatostatin (slows release of insulin and glucagon, controlling rate of nutrient entry to cells)
