What is the ileocolic artery?
The ileocolic artery is the most inferior branch of the superior mesenteric artery (SMA), supplying blood to the distal ileum, ileocecal valve, cecum, vermiform appendix, and the proximal ascending colon.
Are ileocolic and ileocecal the same?
In Animalia that have ceca, the ileocecal region is a subset of the ileocolic region, and the entire range can also be described as ileocecocolic, whereas in some Animalia, the ileocolic region contains no cecum, as the ileum joins the colon directly.
Is the ileocolic artery retroperitoneal?
The ileocolic artery is a large terminal branch of the superior mesenteric artery. It courses inferiorly towards the right iliac fossa, where it splits into a superior and inferior division. Along its course, the artery is entirely retroperitoneal.
How do I know if I have an ileocolic pedicle?
The ileocolic pedicle can be identified by gently placing the ileocecal junction on stretch by pulling it away from the retroperitoneum toward the right lower quadrant using an atraumatic bowel grasper (Figure 2).
What does the left colic artery supply?
The first branch of the inferior mesenteric artery is the left colic artery. The left colic artery supplies blood flow to the distal third of the transverse colon and the entirety of the descending colon.
How do you pronounce ileocolic?
ileo·col·ic.
Is the jejunum real?
The jejunum is the second part of the small intestine in humans and most higher vertebrates, including mammals, reptiles, and birds. Its lining is specialised for the absorption by enterocytes of small nutrient molecules which have been previously digested by enzymes in the duodenum.
What is the female gonadal artery?

Where is inferior Pancreaticoduodenal artery?
The inferior pancreaticoduodenal artery is the first branch of the superior mesenteric artery (SMA). It usually arises at the inferior border of the pancreas or with the first jejunal artery as part of the pancreaticoduodenojejunal trunk.
Where is the left colic artery?
The left colic artery is a branch of the inferior mesenteric artery, arising shortly after its origin from the aorta. It courses upwards posterior to the left colic mesentery and crosses over the anterior surface of the left psoas major muscle, left ureter and gonadal vessels.
What is ileocolic intussusception (ICI)?
Ileocolic intussusception (ICI) occurs when the terminal ileum and its mesentery, the intussusceptum, invaginates through the ileocecal valve into the cecum, the intussuscipiens. From: Clinical Imaging, 2020
What causes Ileocecal intussusception in right ILAC fossa?
Ileocolic or ileocecal intussusception with fluid filled terminal ileum and cecum turned to be the underlying cause of the absent intestinal gases at the right ilac fossa seen on x-ray.
How is the small bowel segment (terminal ileum) of the colon depicted?
The cecum and proximal ascending colon show intramural small bowel segment (terminal ileum) most evidently depicted by its mesentery (mesenteric fat and enhancing vessels), giving the typical lamellar and target sign appearance on axial images. The cecum and terminal ileal loops are dilated and filled with fluid.
What is the anatomy of the ileocecal valve?
Gross anatomy. The ileocecal valve consists of two muscular layers of ileum, an upper and lower lip, that are covered by mucuosa and protrude into the lumen of the caecaum supported by mucosal folds called frenula.
