Posterior Abdominal Wall Flashcards
Deep circumflex iliac artery anastomoses with
Iliolumbar artery
Going around the internal crest of the iliac spine crest
Psoas minor and major
And clinical condition
T12-L5 TP——> lesser trochanter
N: L1-L3 anterior rami
Can get infected due to (TB, cancer, infections in fascia that causes puss buildup) = Psoas Abscess
Sx: flank, back pain ,fever, limp, inguinal mass, *lower ABD pain when extending thigh)
Iliacus
Superior Iliac fossa ——> lesser trochanter
N : Femoral N
Quadratics Lumborum
Iliolmbar lig at lip of iliac crest——> lumbar TP and 12 rib
N: T12-L4 anterior rami
Medial Arcuate Lig
Fascia over the psoas major (from L1 body to L1 TP)
Lateral to the median arcuate lig
Lateral Arcuate Lig
Fascia thickening over the Quadratus Lumborum (L1 TP to 12th rib)
Median Arcuate Lig
Tendon facia of crura of diaphragm over the Aorta
Unites the left and right crura
Esophagus in the esophagus hiatus is above it
IVC begins at
L5 to the right of the midline
For venous return from ABD to the portal venous system (hepatic Vein)
Makes the Lumbar Veins
Azygos vein + Lumber veins
Anastomoses to go thorax to make SVC
Where does the LEFT Gonadal Vein drain into
Left renal vein ——> IVC (on right side)
The right gonadal ——> IVC directly
Inferior mesenteric vein
Empty to portal vein to enter hepatic vein
Hepatic Veins empty into what
IVC
Caval Opening
T8
IVC goes through into the ABD cavity
Right Phrenic N goes through to the ABD cavity
*both go through diaphragm
Esophageal Hiatus
T10
Esophagus
Ant + Post Vagal trunks
*both go through diaphragm
Aortic Hiatus
T12 Aorta Thoracic Duct Sometimes Azygos and Hemiazygos * go behind diaphragm
Esophageal hiatus pierces what
The right crura (from L1-L4) some from left of aortic hiatus
