Flashcards in Adrenal Physiology Deck (18)
List the parts of the adrenal gland
What are the 3 zones located in the adrenal cortex?
Which cells are located in the adrenal medulla?
What controls hormonal release in the zona glomerulosa?
RAAS (angiotensin II)
Which hormone is secreted from the zona glomerulosa?
What controls hormonal release in the zona fasciculata?
What hormones are secreted from the zona fasciculata?
What controls hormonal release in the zona reticularis?
What hormones are secreted from the zona reticularis?
Androgens (sex hormones)
What controls hormonal release in the adrenal medulla?
Sympathetic nervous system
What hormones are secreted from the adrenal medulla?
Catecholamines (adrenaline, noradrenaline)
Outline the hypothalamus-pituitary-adrenal cortex axis
HYPOTHALAMUS secretes CRH which stimulates anterior PITUITARY to secrete ACTH which stimulates the ADRENAL GLAND to secrete cortisol
Which parts of the H-P-adrenal cortex axis does cortisol inhibit in negative feedback?
Which system regulates aldosterone release?
What is the effect of cortisol upon the CNS?
Loss of libido
What is the effect of cortisol upon bone?
What is the effect of cortisol upon metabolism?
Increases breakdown of carb, lipid and protein
