adrenals Flashcards
adrenal structure: recall the anatomy of the adrenal gland; list the zones of the adrenal cortex; recall the products of the adrenal cortex and medulla
where are the adrenal glands located
above kidneys
where does left adrenal vein drain
renal vein to inferior vena cavae
where does right adrenal vein drain
inferior vena cavae
how many arteries and veins do adrenal glands have
many arteries, one vein
2 sections of adrenal gland
medulla, cortex
sections of adrenal cortex (outer to inner)
zona glomerulosa, zona fasiculata, zona reticularis
hormones produced in adrenal medulla
catecholamines: adrenaline, noradrenaline (neurotransmitter), some dopamine
hormones produced in adrenal cortex
corticosteroids
cells in adrenal medulla
chromaffin cells
types of cortichoids
mineralcorticosteroids (aldosterone), glucocorticoids (cortisol), some sex steroids (androgens and oestrogens)
which zone produces aldosterone
zona glomerulosa
which zones produce cortisol
zona fasiculata, zona reticularis
which is the largest zone
zona fasciculata (cortisol production)
what is produced in the medulla
adrenaline
as the spleen is very close to the left adrenal glands, what is it at risk with
left adrenalectomy (surgical intervention to remove left adrenal gland)
