Once you know this you can quickly determine what the results of HYPER or HYPO function will be. ie. . . ACTH stimulates the adrenal cortex to release cortisol.
What does cortisol do? Think increased GLUCOSE, decreased IMMUNITY, decreased INFLAMMATION. So, with HYPER function of the Adrenals, we will have even more glucose, less immunity, and less inflammation. . . what would someone like this look like? This is Cushing’s.
The opposite will lead to Addison’s. So think of how each gland interrelates, then simply think of what each hormone does. From there it becomes much easier to figure out what the resulting assessment findings will uncover.
production and release of TSH when stimulated by the hypothalamus.
What does thyrocalcitonin do?
lowers blood calcium by inhibiting bone resorption
What does the parathyroid do?
produce PTH (parathyroid hormone) which raises blood Ca levels
Where are the adrenal glands located?
on top of the kidneys
What are the two endocrine tissues within the adrenal glands?
adrenal medulla and adrenal cortex
Name the two major hormones secreted by the adrenal medulla and their functions:
The adrenal medulla secretes two catecholamines: epinephrine, and norepinephrine. Epinephrine prepares the body for the fight or flight response by converting glycogen to glucose and increasing HR. Norepinephrine produces extensive vasoconstriction.
What stimulates the adrenal cortex?
ACTH adrenocorticotropic hormone from the anterior pituitary gland
What does ACTH stimulate the adrenal cortex to produce?
