Adrenal Glands Flashcards
What space is are the adreal glands and kidneys located in?
perirenal space
The right adrenal gland is shaped like a ______ or ________.
triangle or pyramid
Where is the right adrenal gland located on the upper pole of the right kidney?
located superior, anterior, and on the medial aspect of the upper pole of the right kidney
Portions of the right adrenal gland extend _____ to the iVC
posterior
The crus of of the diaphragm lies _____ and _____ to the right adrenal gland.
medial and posterior
The left adrenal gland is shaped like a _______.
crescent
Where is the left adrenal gland located on the uper pole of the let kidney

The Ao and crus of the diaphragm are located _____ to the left adrenal gland and the tail of the pancreas is located ______ to the left adrenal gland

Adrenal anatomy
Adrenal Cortex
- produces steroid hormones (aldosterone, cortisol, androgens) these ACH are regulated by the adrenocorticotropic hormones of the anterior pituitary gland- these glands function together to regulate production……a dec in adrenal cortical function inc ACTH which stimulates the cortex, or an inc in ACH leads to drop in ACTH secretions, whihc leads to drop in activity of adrenal cortex
- peripherary of the gland
Adrenal Medulla
- produces catecholamines (epinephrine/arenaline, norepinephrine)
- inside/center of gland
_____ of the adrenal gland and anterior pituitary gland may overproduce or underproduce ACTH and ACH
tumors
Sonographic appearance of an adrenal gland
adrenal cortex is hypoechoic and typically less echogenic than the suroudinging retroperitoneal fat
adrenal medulla is seen as an echogenic linera structure within
A singe vein drains each adrenal gland, what are they and what do they drain into?
right - right suprarenal vein drains into IVC
left - left suprarenal vein drains into the left renal vein
What 3 arteries supply each adrenal gland
suprarenal branch of inferior phrenic art
suprarenal branch of aorta
suprarenal branch of renal artery
T/F - TSonographic appearance of adrenal masses does not allow differenetiation between adenoma, carcinoma, pheochromocytoma and metastases.
T
Most adrenal adenomas are ______ but can be ______.
nonhyperfunctioning
hyperfunctioning
What syndromes are the result adrenal hyperfunctioning?
Cushing’s Syndrome (hypercortisolism)
Conn Syndrome (primary aldosteronism)
Hirsutism (abundance of hair growth)
cushing’s is assoc with
steroids
inc ACTH from a pituitary adenoma
primary adrenal adenoma
ectopic ACTH (oat cell ca, small cell lung ca)
