What is abduction of the arm?
In general terms, abduction in the anatomical sense is classified as the motion of a limb or appendage away from the midline of the body. In the case of arm abduction, it is the movement of the arms away from the body within the plane of the torso (sagittal plane).
Which muscle is responsible for arm abduction and rotation?
The supraspinatus is responsible for the first 15 degrees of abduction; the deltoid, an intrinsic muscle of the shoulder that is not a rotator cuff muscle, is responsible for abduction from 15 to 90 degrees. The infraspinatus and teres minor both aid in lateral, or external, rotation of the arm at the shoulder.
