What is the appendicular artery?
The appendicular artery is a branch of the ileal or posterior cecal branch of the ileocolic artery, which is from the superior mesenteric artery. It courses posteriorly to the terminal ileum in the free wall of the mesoappendix to supply the appendix.
What Innervates the appendix?
Sympathetic and parasympathetic branches of the autonomic nervous system innervate the appendix. This is achieved by the ileocolic branch of the superior mesenteric plexus. It accompanies the ileocolic artery to reach the appendix.
What does ileocolic artery supply?
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.
Is there an artery near the appendix?
Anatomical terminology The appendicular artery, also known as appendiceal artery, commonly arises from the terminal branch of the ileocolic artery, or less commonly from the posterior cecal artery or an ileal artery. It descends behind the termination of the ileum and enters the mesoappendix of the vermiform appendix.

What is the anatomy of the appendix?
appendix, formally vermiform appendix, in anatomy, a vestigial hollow tube that is closed at one end and is attached at the other end to the cecum, a pouchlike beginning of the large intestine into which the small intestine empties its contents. It is not clear whether the appendix serves any useful purpose in humans.
Is ileocolic same as ileocecal?
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. Ileocecal valve. Ileocolic artery.
What is ileocolic Junction?
Background: The ileocecal junction (ICJ) appears to be a specialized segment of the gut which regulates the passage of the chyme from the ileum to the cecum. The balloon and manometric catheters were introduced into the cecum and ileum by colotomy and ileotomy, respectively.
What organs are near the appendix?
Organs found in the right lower quadrant include the appendix, the upper portion of the colon, and the right ovary and the Fallopian tube in women. The right lower quadrant may be assessed when diagnosing appendicitis, in which case, this quadrant would be tender and painful.
