Week 3-L3-adrenal gland Flashcards
where are the adrenal gland found
above the kidney
adrenal gland blood supply
many arterial supply but only single venous drainage
right adrenal vein drains into the IVC but left adrenal vein drains into renal vein
draw gross anatomy of the adrenal gland
top->liver and spleen
middle adrenal glands and arterial supply
bottom kidney arterial and venous supply
across IVC and aorta
micro anatomy of adrenal glands
adrenal cortex and adrenal medulla
adrenal cortex made up of
Zona glomerulosa, fasciculate and reticularis
adrenal cortex secretion
corticosteriods e.g.cortisol
adrenal medulla
catecholamines e.g. adrenaline
corticosteroids
mineralocorticoids-aldosterone, glucocorticoids-cortisol, sex steroids-androgen and oestrogen
catecholamines
adrenaline and noradrenaline and dopamine
aldosterone secretion
zona glomerulosa
cortisol androgen and oestrogen secretion
zona fasciculata and reticularis
adrenal cortex micro anatomy
capsule, zona glomerulosa, fasciculata. reticularis and medulla where hormones are transported to the central vein to the blood stream
what is a steroid
derived from cholesterol
adrenal gland secretions precursor
cholesterol
is adrenaline a steroid
no because it is not a cholesterol derived product
number of carbon atoms in a cholesterol molecule
27
enzyme definition
protein that catalyses a specific reaction
