Posterior abdomen wall Flashcards
what is the function of the kidney
filter blood, produce urine and secrete renin
what layers are the kidneys between
between parietal peritoneum and musculature of posterior abdominal wall and diaphragm
which direction is the inferior pole of the kidney oriented
more lateral and hilum anteromedially
What is posterior to the kidneys
diaphragm, psoas major, quadratus lumborum, transversum abdominis, subcostal n, iliohypogastric, ilioinguinal n
what structures are anterior to the right kidney
liver, duodenum, ascending colon
what structures are anterior to the left kidney
stomach, spleen, pancreas, jejunum, descending colon
describe the renal fascia
each kidney is surrounded with fat and fascia
anterior and posterior layers that blend medially with adventitia or renal vessels
describe the renal fat
pararenal fat is found external to renal fascia
perirenal fat is found between kidney and the renal fascia
Describe structures in the renal sinus
open sapce in kidney with renal calyces, renal pelvis, vessels, nerves and lymph
Describe the cortex of the kidney and what is in it
glomeruli, proximal and distal convoluted tubules with medullary rays as well
Describe the medulla of the kidney
collecting tubules with renal pyramids
cortical columns
what is the apex of the renal pyramid called
renal papillae
how many minor calyces are in a major
2-3
What is the function of the suprarenal glands
endocrine
what hormones does the suprarenal gland secrete
cortisol, aldosterone, androgens, epi and norepi
What separates kidney and suprarenal gland
thin septum
what are the shapes of the suprarenal glands
right is pyramidal shaped
left is crescent shaped
What is the function of the cortex of suprarenal glands
produce the steroids like glucocorticoids and mineralocorticoids
What is the function of the medulla of the suprarenal glands
postganglionic sympatheticneurons, epinephrine,noreepi
Describe the aa that supply suprarenal glands
superior suprarenal a, middle and inferior
where do the suprarenal aa get their supply from
superior is from inferior phrenic a
midd is from aorta, LV1
inferior is from rectal a
Describe venous drainage of suprarenal glands
right suprarenal vein drains to IVC
left suprarenal vein joins left renal vein then enters IVC
Where do the lymph nodes around suprarenal glands drain
lumbar lymph nodes
What is the function of diaphragm
respiration
decreases intrathoracic pressure and increases intraabdominal pressure
Describe the superior and inferoir surfaces of diaphragm
superior is convex
inferior is concave
the right and left domes of the diaphragm reach what rib level in expiration
5th rib
Describe the components of the central tendon
3 leaves- right left and central
attached to pericardium via pericardiocophrenic ligament
what are the muscular portions of diaphragm
sternal– smallest, attached to xiphoid
costal– largest inserts into internal ribs 7-12
lumbar portion– attaches to LV1-LV3 on R crus
attaches to LV1-LV2 on L crus
What are the 3 arcuate ligaments of diaphragm
median arcuate
medial arcuate
lateral arcuate
what forms the esophageal hiatus
the Right crus folding in on itself
where is the median arcuate ligament
tendinous arch between left and right crura
