Anatomical terminology

The appendix (pl.: appendices or appendixes; also vermiform appendix; cecal (or caecal, cæcal) appendix; vermix; or vermiform process) is a finger-like, blind-ended tube connected to the cecum, from which it develops in the embryo.

The cecum is a pouch-like structure of the large intestine, located at the junction of the small and the large intestines. The term "vermiform" comes from Latin and means "worm-shaped". In the early 2000s the appendix was reassessed and is no longer considered a vestigial organ.[1][2] The appendix may serve as a reservoir for beneficial gut bacteria.
