|A||The blood supply is through the appendicular artery|

a. The appendix, ileum, and ascending colon are all derived from the midgut.
b. The appendix first appears at the 8th week of gestation as an outpouching of the cecum and gradually rotates to a more medial location as the gut rotates and the cecum becomes fixed in the right lower quadrant.
c. The appendiceal artery, a branch of the ileocolic artery, supplies the appendix.
e. The length of the appendix varies from 2 to 20 cm, and the average length is 9 cm in adults.
f. The base of the appendix is located at the convergence of the taeniae along the inferior aspect of the cecum, and this anatomic relationship facilitates identification of the appendix at operation.
g. The tip of the appendix may lie in a variety of locations. The most common location is retrocecal but within the peritoneal cavity. It is pelvic in 30% and retroperitoneal in 7% of the population.
