MUSCLES THAT MOVE THE HUMERUS (ARM)

The six movements of the shoulder are:

flexion, extension, abduction, adduction, medial rotation, and lateral rotation

The pectoralis major is predominantly involved in flexion. Its antagonist would be involved in extension. Hence, the latissimus dorsi would be its antagonist ...
