Etymology: "Tricepses" is the plural of "triceps," the name for the large muscle at the back of the upper arm that straightens the elbow. The singular comes from Latin "triceps," meaning "triple-headed," built from "trēs" ("three") and "caput" ("head"). The name describes the muscle's three points of origin, which join into a single tendon at the elbow. Latin "caput" is the same word that gives English "capital," "captain," and "chapter," all ultimately tied to the idea of the head. The Latin adjective was a natural name for a muscle with three heads, and anatomists borrowed it directly for this purpose, so the plural follows the Latin pattern of a word ending in "-ceps," which keeps its "-ceps" form when made plural in English.
