Editing Triceps (section)

===Etymology===
It is sometimes called a three-headed muscle (Latin literally three-headed, ''tri'' - three, and ''ceps'', from ''caput'' - head), because there are three bundles of muscles, each of different origins, joining at the elbow. Though a similarly named muscle, the [[triceps surae]], is found on the [[lower leg]], the triceps brachii is commonly called the triceps.

Historically, the plural form of ''triceps'' was ''tricipites'', a form not in general use today; instead, ''triceps'' is both [[Grammatical number|singular]] and [[plural]] (i.e., when referring to both arms).
