The appendix, a narrow diverticulum of variable length but usually about 8 cm long, arises from the posteromedial wall of the caecum below the ileocaecal orifice . It is covered with peritoneum and connected to the termi– nal ileum by a mesentry, the mesoappendix, which contains the appendicular artery. Much lymphoid tissue is found in its wall. It is very mobile and therefore its relations are variable; most commonly it lies in a retrocaecal position, but not infrequently it is in the pelvis .Appendicitis – inflammation of the appendix – is usually a consequence of obstruction of its lumen by faeces.
