BICEPS

A 'biceps' is a muscle from either of two muscle pairs (right and left) in the body. ''Biceps'' is the Latin adjective meaning ''two-headed''. These muscles are so-called because each has two insertions at its upper end.

★ In general usage, the biceps is the biceps brachii, the prominent muscle on the inside of each upper arm, popularly associated with bodily strength because it can be flexed very visibly.

★ Less commonly, the ''biceps'' is the biceps femoris, one of the hamstring muscles of the underside of each thigh.
