Is a vestigeal organ, a tubular structure  of about 5 cm with a lumen
        It is attached to the caecum
        In the right iliac fossa
        McBurney's point corresponds to the base of appendix - a point which is the
        junction of lateral 1/3 and medial 2/3 of a line which is drawn from the umbilicus to the
        anterior superior iliac spine.

Features of the appendix
        Found at the point where the three taeniae coli converge on the postero medial wall of the caecum
        It opens into the caecum at one end and the other end is blind
        The taeniae coli merge into a complete longitudinal muscle layer over the appendix
        Mesoappendix : a peritoneal fold enclosing the appendicular vessels.
        It is a prologation of the mesentery of the terminal ileum.
        It contains the appendicular artery - a branch of the posterior caecal artery
        The position of the appedix in relation to the caecum and terminal ileum is variable

        Varies considerably in length and circumference
        The lumen is narrow may admit a match stick
        Peritoneal layer - adventitia
        Muscular coat
        Longitudinal and circular (outer and inner layers) muscle layer
        Has a well developed submucous coat containing lymphoid follicles
        The lumen has longitudinal folds of mucous membrane

Blood supply
        Appendicular artery a branch of ileo- colic artery
        Appendicular vein drains into ileo-colic vein   portal vein

Applied Anatomy
        Inflammation of the appendix        Appendicits
          During inflammation : tenderness       in the McBurney's point.

Various positions of the appendix
2.Post ileal
4. Subcaecal
5. Pelvic
