duodenal blood supply
Upper half by superior pancreatico- duodenal branch of gastroduodenal artery.
Lower half by inferior pancreaticoduodenal branch of superior mesenteric artery.
venous drainage of duodenal
upper half -> superior pancreaticoduodenal into portal vein
lower half –> inferior pancreaticoduodenal into superior mesenteric vein
lymph drainage of duodenal
upward -> celiac nodes
downward –> superior mesenteric nodes
duodenojejunal flexure is connected tothe diaphgram by
the ligament of Treitz
jejunum mesentery is attached to the posterior abdominal wall
above and to the left of the abdominal aorta.
The ileal mesentery is attached to
below and to the right of aorta.
retrocecal recess contains
vermiform appendix, femoral nerve, and lateral cutaneous nerve of thigh.
blood supply of cecum
The anterior and posterior caecal branches of ileocolic artery (a branch of superior mesenteric artery
In relation to the anterior abdominal wall, the base of appendix is situated
one third of the way up the line joining the right anterior superior iliac spine to the umbilicus
blood supply of appendix
The appendicular branch of posterior caecal artery
Afferent nerve fibers concerned with conduction of visceral pain from appendix enter spinal cord at level of
T10 segment
the colon relation to protonium
retroperitoneal
small intestine relation with protonium
totally covered , freely movable
ascending colon is placed in
right hypochondriac + right lumber regions
ascending colon posterior relations
Quadratus lumborum, origin of transverses abdominis, iliacus, and lower end of R. kidney.
