(From appendo, to hang from; vermis; a worm; and forma, shape). On one side of the bottom of the cce-cum lies an appendix resembling a small intestine, nearly of the same length with the ccecum, but more slender. It is so called from its resemblance to an earthworm, and its common diameter is about a quarter of an inch. By one extremity it opens into the bottom of the ccecum, the other extremity is closed. Its structure is like that of the intestines in general; and the internal coat is folliculous and reticular, like that of the duodenum. Its use is not known; it is also called addi-tamentum coli, and by some ecphyas.
