In human anatomy, the vermiform appendix (or just appendix) is a blind ended tube connected to the cecum. It develops embryologically from the cecum. In adults, the appendix averages 10cm in length but can range from 2-20cm. 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.
An operation to remove the appendix is an appendectomy.
The most common diseases of the appendix (in humans) are:
