Adrenal Disorders Flashcards
What is the difference between a functional tumor & an adenoma
Functional tumors are hormone secreting & adenomas are benign
What are the 3 main substances secreted by the adrenal cortex
- aldosterone (mineralcorticoid - granulosa)
- cortisol (glucocorticoids - fasciculata)
- androgens (reticularis)
What is the main substance secreted by the adrenal medulla
catecholamines (epi & norepi)
What is adrenal insufficiency
rare disorder that occurs when there is insufficient function of the adrenal cortex leading to underproduction of corticosteroids
What are the classifications of adrenal insufficiency
- primary (Addison’s): dysfunction of the adrenal gland
- secondary: deficiency of ACTH due to dysfunction of the pituitary gland
- tertiary: deficiency of ACTH due to dysfunction of the hypothalamus
What happens when there is an increase in ACTH
glucocorticoids & androgens increaseW
Why doesn’t aldosterone increase when there is an increase in ACTH
regulation from the renin-angiotensin-aldosterone system
