Vermiform appendix

In human anatomy, the vermiform appendix (or appendix) is a blind ended tube connected to the cecum. It develops embryologically from the cecum. In adults, the appendix averages 10 cm in length but can range from 2-20 cm. The diameter of the appendix is usually less than 7-8 mm. While the base of the appendix is at a fairly constant location, the location of the tip of the appendix can vary from being retrocaecal to being in the pelvis to being extraperitoneal. In most people, the appendix is located at the lower right quadrant of the abdomen. In people with situs inversus, the appendix may be located in the lower left side.
