The biceps muscle is located in the arm. The biceps muscle is composed of two parts, the short biceps and the long biceps, which are both connected to the scapula. The biceps is connected to the articular capsule of the humerus. The short and long biceps share a tendon that is connected to the radius bone. The biceps muscle aids in bending the arms, but also in performing rotational movements. The musculocutaneous nerve innervates it.
