The teres major muscle functions in both adduction and medial rotation of the humerus. The antagonists of this muscle are those which abduct the humerus and rotate it externally. The infraspinatus, posterior deltoid, and teres minor all function as antagonists of the teres major.

The muscle of the pectoralis is antagonist to the latissimus dorsi during the shoulder adduction. The anterior fibers are involved in shoulder abduction when the shoulder is externally rotated.
The teres major muscle is considered to be antagonistic to the teres minor muscle. The teres major muscle is a larger muscle located in the upper arm that works to extend, medially rotate, and adduct the arm, while the teres minor muscle is a smaller muscle that works to laterally rotate the arm.
There are more than one: The deltoid, supraspinatus, infraspinatus, teres major and minor and the subscapularis.
The antagonist of teres minor is: To medial rotation: latissimus dorsi, long head of triceps, pectoralis major, subscapularis. In Extension of humerus: latissimus dorsi, posterior deltoid and long head of triceps
synergists: trapezius, teres major and minor, flexors, biceps brachiiantagonists: deltoid, extensors, triceps brachii
It is the middle deltoidIt is the Deltoid Muscle .
Teres Major originates on the dorsal aspect of the inferior angle of the scapula and inserts on the medial lip of the intertubercular groove of the humerus. Teres Major can internally rotate and adduct the arm.
Little lat is the nickname for the teres major. It got the nickname due to how close it is to the latissimus dorsi.
The muscles that are involved in the circumduction of the shoulder joint are the pectoralis major, deltoid, supraspinatus, long head of triceps, biceps brachii, subscapularis, infraspinatus, coracobrachialis, teres major and minor and the latissimus dorsi.
