The best way to build the muscles in the arm (like biceps and triceps) is to use the concept that most people don't know about...which is the fact that these muscles grow also when working other ones.

There is not a single muscle that rotates the upper arm. The name of the muscle that contributes in rotation of the upper arm is deltoid muscle.
Skeletal muscle is associated with the upper arm.
The brachialis is a muscle in the upper arm that flexes the elbow joint.
While one muscle contracts, the other muscle in the pair returns to its original length. The main muscle that bends your upper arm is called the Biceps brachii. The action is called flexion at the elbow. This muscle is on the "front" of the arm. The muscle that acts against this one is called the Triceps brachii. Its' action is extension at the elbow. This muscle is on the "back" of the arm. See the link below:

A muscle doesn't rotate the shoulder. The ligaments that connect your shoulder blade to your arm, to your rib cage all work in a ball and socket type of way allowing you to rotate your arm 360o.
