The Biceps Muscles
In this lesson you will learn about the muscles on the front side of your upper arm. The biggest and strongest muscle in this area is the biceps brachii with its two heads - A short head and a long head. That's where the name "Bi - Ceps" comes from (Bi = 2) Brachii means arm. The functions of the biceps are flexing (bending) the arm and rotating the forearm. There are two more muscles in this area: Brachialis and Brachioradialis, which are located between biceps, triceps and the forearm muscles. When we refer to the biceps, we often mean all the arm muscles on the front side of the upper arm, including the upper arm portion of the forearm muscles.
