Etymology: "Ceca" is the plural of "cecum," and the plural form is the one most readers meet first, since the anatomical term appears mostly in discussions of animal digestion. The singular "cecum" comes from Latin "caecum," meaning "blind," in the sense of a pouch closed at one end, like a dead-end passage. The same Latin adjective gave English "caecal," the adjectival form used for structures associated with this pouch. The Latin "caecus" was the source of the word for blindness in many European languages, and the anatomical sense reflects the pouch's closed, blind end. Because the sac opens only at one side, it is a dead end for the contents of the gut, and that image of an enclosed, unexitable space is what the Latin word carries into the body's structures.

Synonyms: blind gut, caecum, cecums
