cecum is :
that part of the large intestine that lies below the level of the junction of the ileum with the large instestine
cecum situated in the :
right iliac fossa
cecum long is :
6-7.5 cm long and is completely covered with peritoneum
antrior to the cecum
coils of the small intestine
anterior abdominal wall
part of the greater omentum
posterior to the cecum
two muscle iliacus muscle , psoas muscle
two nerve femoral nerve , lateral cutaneous nerve
medial to the cecum
the appendix rises from the cecum on the medial side
blood supply of of the cecum are :
posterior and anterior cecal arteries from the ileocolic artery a branch of the superior mesenteric artery
veins drainage of the cecum :
correspond to the arteries and drain into superior mesenteric vein
lymph drainage of the cecum :
the superior mesenteric nodes
nerve supply of the cecum :
the superior mesenteric plexus
the appendix varies in length from
6 to 9 CM
the appendix lies in
the right iliac fossa
MCBurneys point joining
the right anterior superior iliac spine to the umbilicus
the most common sites of the appendix
pelvic and retrocecal
arteries of the appendix
the appendicular artery is a branch of the posterior cecal artery
veins drainage of the appendix
the appendicular vein drains into the posterior cecal vein
lymph drainage of the appendix
into one or two nodes lying in the mesoappendix
eventually into the superior mesenteric nodes
ascending colon long is
13 cm
ascending colon lies in
the right lower quadrant
ascending colon extends
upward from from the cecum to the inferior surface of the right lobe of the liver
anteriorly to the ascending colon
coils of small intestine
the greater omentum
the anterior abdominal wall
posteriorly to ascending colon
iliacus iliac crest the quadratus lamborum the origin of the transversus abdominis lower lobe of the right kidney the iliohypogastric iliolnguinal cross behind it
blood supply to ascending colon :
the ileocolic and right colic branches of the superior mesentric artery
vein drainage of the ascending colon
correspond to the arteries and drain into the superior mesentric vein
