The vermiform appendix is a diverticular structure that emerges from the caccum's posteromedial wall about 2 centimetres below its ileocaecal junction.
The length of the appendix varies between 2 and 20 centimetres (average 9 cm). The standard width is about 5 millimetres.
The angulated circular lumen in the appendix is small in comparison to the thickness of its wall. Starting from the inside and working out, the four layers that make up the appendix wall are the mucosa, submucosa, muscular layer, and serosa.Appendix has 3 parts i.e. base, body and tip.
The appendix can be located in the right iliac fossa of majority of people. The beginning of the appendix is always in the same location, but the rest of the organ can be in any one of the following places. These roles are frequently denoted by the hour hand that moves around the face of a clock.Intraluminal capacity of appendix is 0.1mL
Its function is not fully understood, but several theories have been proposed:
Overall, the appendix is considered to be a non-essential organ and the body can function normally without it. One theory suggests that the appendix 'reboots' the digestive system after an illness that causes diarrhea by acting as a repository for healthy bacteria. This theory is supported by the observation that the appendix is present in most people who have diarrhea. It is possible to remove the appendix through surgical procedures with no discernible adverse effects on the patient's health.
