Cecal appendage is a term used to describe a finger-like structure attached to the cecum, which is a pouch-like structure located at the beginning of the large intestine. It is also known as the vermiform appendix, and in some cases, it may be referred to as the ileocecal valve. The term "vestigial" is also sometimes used to describe this structure, as it is believed to have evolved to serve a purpose that is no longer necessary in humans. Other synonyms for cecal appendage include the appendicular process, cecal diverticulum, and cecoappendiceal orifice. Despite its minimal function, the cecal appendage can cause significant health problems if it becomes inflamed or infected, such as in the case of appendicitis.
