Answer to Ms. Irrelevant to the Rescue
Correct answer is A, the ileocolic. The single appendicular artery is a branch of the ileocolic artery. If the appendicular artery is inadvertently cut during an appendectomy, a likely possibility given the expertise of the surgical team, it is possible to stop the blood supply to the appendix by pinching the ileocolic artery momentarily to then use a Bovie machine to control the bleeding. Pinching off a jejunal artery (line 4), would have no effect on stopping the bleeding of an injured appendectomy artery.
= Ileocolic a.
= Right colic a.
= Middle branch
= Jejunal branch
= Continuation of superior mesenteric a.
