The muscles of the Arm

There are three major muscle groups in the arms:

The biceps brachii, a two-headed muscle with point of origin under the deltoid and point of insertion below the elbow.
The triceps brachii, a three-headed muscle which works in opposition to the biceps, also attaching under the deltoid and below the elbow.

The forearm, involving a variety of muscles on the outside and inside of the lower arm that control the actions of hand and wrist.
