Arm flexion
Arm flexion represents rotation in the anatomic plane such that the distal humerus moves ventrally. Is represents raising the arm and isolated flexion can achieve approximately 150-170° of movement. The opposite movement is arm extension and contributes to the combined movement of shoulder circumduction.
It is produced by:
- deltoid (anterior fibers)
- pectoralis major (clavicular part)
- biceps brachii (long and short heads)
- coracobrachialis
