What do the inferior phrenic arteries supply?
Diaphragm and suprarenal gland

Is the aorta to the left or right of the vena cava? Does it run anterior or posterior at their bifurcation? Does the artery run medial or lateral?
Runs to left. Bifurcates anteriorly. Artery runs laterally.

How do the right and left suprarenal glands look in comparison to one another?
Right is pyramidal, left is semilunar

What does the suprarenal gland cortex appear to be yellow?Because it has a high lipid content.What are the developmental origins or the cortex of the suprarenal glands?Originates around week 5 from mesodermal tissue near gonads.What % of the suprarenal gland is the cortex?80-90%What are the 3 zones that produce mineralocorticoids and glucocorticoids in the suprarenal gland cortex?Glomerulosa, fasciculata, reticularisWhat is the % composition of the medulla of the suprarenal gland?20%What is the color of the medulla of the suprarenal gland?Reddish brownWhat are the developmental origins of the medulla of the suprarenal gland? Where does it arise from?Ectoderm. Arises from the neural crest.What is the blood supply of the suprarenal glands? Where does each artery arise from?Superior suprarenal artery: inferior phrenics Middle suprarenal artery: aorta Inferior suprarenal artery: renal arteryDescribe the venous drainage of the suprarenal gland. Are the left and right different? How is this different from other structures?Does not have identical venous partners.What is the relationship of the left renal vein and the SMA?Left renal vein travels underneath the SMA to meet up with the IVC.What is the growth of the medulla and cortex like during embryology and birth?The medulla is invaginated in the cortex during development. The cortex has layers that grow around the medulla. After birth, the medulla grows.What kind of pain presents with an abdominal aortic aneurysm?Pulsating mass in the aorta. Back pain! The aorta is retroperitoneal! Also may present with shock (pale, tachycardia, hypotension)The following is a CT scan of an abdominal aortic aneuryism. Note how large it is.What is deep vein thrombosis?When a clot breaks off in the venous system, goes to the heart, and then goes to the lungs via the pulmonary arteries.What is a pheochromocytoma?(catecholamine is epi and norepinephrine) Where arrows are pointing is the adrenal gland.
