Study Notes
Appendix Overview
- The appendix is a narrow, wormlike tube, measuring between 2-20 cm in length, with an average of approximately 9 cm.
- It is the narrowest part of the gastrointestinal tract (GIT).
Anatomical Features
- Three taeniae coli found on the ascending colon and cecum converge at the base of the appendix, blending into its longitudinal muscle structure.
- The appendix is completely enveloped by peritoneum, indicating its abdominal cavity location.
Mesoappendix
- Mesoappendix is a triangular fold of peritoneum associated with the appendix.
- The base of the mesoappendix attaches to the posterior (left) layer of the mesentery.
- The border of the mesoappendix encases the appendix, while the free border contains vital appendicular vessels, which supply blood to the appendix.
