diaphragmatic aperutres
several small openings in the diaphragm that allow for passage of the superior epigastric vessels, lymphatic vessels, sympathetic trunk, and greater and lesser omentums
esophageal aperture
aperture found within the right crus, roughly in midline posterior to the central tendon at the T10 vertebral level; esophagus, anterior and posterior vagal trunks, esophageal vessels, and some lymphatic vessels pass through this aperture
caval aperture
aperture found within the central tendon at T8/T9 IV discs; the IVC and a few lymphatic vessels pass through this aperture
aortic aperture
aperture found b/t R. & L. crura at T12 vertebral level, and is not actually an opening w/n the diaphragm but rather an opening posterior to the diaphragm
aortic aperture
the aorta, thoracic duct, and sometime azygous v. pass through this aperture; opening posterior to the diaphragm; respiratory changes in the shape of the diaphragm don't affect blood flow through aorta
kidneys
paired retroparitoneal bean shaped structures that lie on the posterior abdominal wall on either side of the vertebral column at T12 to L3 levels; covered by pararenal fat pads that help support and anchor kidneys in paravertebral gutters
renal hilum
found on the medial concave surface of each kidney; the renal vein, renal artery, and renal pelvis pass through this structre from anterior to posterior
internal anatomy of kidney
includes the renal cortex and medulla, renal pyramids, renal papillae, minor and major calices, and renal sinus
ureters
retroperitoneal, paired muscular ducts that run inferiomedially and cross the external iliac artery ("water over the bridge); before running along the lateral wall of the pelvis to transport urine from kidneys to the urinary bladder
blood supply to ureters
blood supply via branches from the renal arteris, gonadal arteries, and abdominal aorta
abdominal aorta
artery that descends from the thorax through the aortic aperture of the diaphragm at the T12 level into the abdomen; ends by dividing into R. & L. common iliac arteries at the L4 vertebral level
gonadal arteries
long, slender vessels that arise anteriorly from the aorta infreior to the renal arteries and descend into the pelvis to supply the ovaries or travel through the inguinal canal to reach the testes
IVC
begins as the union of the R. & L. common iliac veins at the level of the L5 vertebral level and ascends on the right side of the body before entering the thorax via the caval aperture of the diaphragm
IVC
the renal veins and thr right gonadal vein drain into this vein
left gonadal vein
drains into the left renal vein
right gonadal vein
vein that drains into the IVC along with the renal veins
Subcostal n.
VPR of T12; travels below the inferior border of the 12th rib and lies on surface of quadratus lumborum; the nerve passes b/t transversus abdominus and internal oblique to supply these muscles and skin of anterolateral abdominal wall
lumbar plexus
network of VPR of L1-L4; found w/n psoas major; receives postganglionic nerves from sympathetic trunk; gives rise to several major nerves
lateral femoral curaneous n.
VPR's of L2-L3; runs on surface of iliacus, passes posterior to inguinal ligament to supply skin of lateral thigh
obturator n.
VPR's of L2-L4; found on medial side of psoas major; descends into pelvis and through obturator foramen (w/ obturator a.) to supply adductor muscles of thigh
Femoral n.
VPR's of L2-L4; runs along lateral border of psoas major and innvervates the iliacus m.
lumbosacral trunk
VPR's of L4-L5; travels into pelves to contribute to sacral plexus (S1-S4)
