The teres major muscle (from Latin teres, meaning "rounded") is positioned above the latissimus dorsi muscle and assists in the extension and medial rotation of the humerus. This muscle is commonly confused as a rotator cuff muscle, but it is not, because it does not attach to the capsule of the shoulder joint , unlike the teres minor muscle ...
The latissimus dorsi can be remembered best for insertion as "A Miss Between Two Majors". As the latissimus dorsi inserts into the floor of the intertubercular groove of the humerus it is surrounded by two major muscles. The teres major inserts medially on the medial lip of the intertubercular groove and the pectoralis major inserts laterally ...

[1] [3] [4] The trapezius, infraspinatus, and brachialis muscles are most active at the beginning of the pull-up; the latissimus dorsi, teres major, and biceps brachii reach peak activity during the middle of the movement, and the triceps brachii and subscapularis experienced maximum activity at the top of the movement. [5]
pectoralis major, coracobrachialis, biceps brachii, anterior fibers of deltoid. Arm extension [15] The humerus is rotated out of the plane of the torso so that it points backwards (posteriorly) latissimus dorsi and teres major, long head of triceps, posterior fibers of the deltoid Medial rotation of the arm [16]
The lower posterior boundary is called the posterior axillary fold and this is a compound structure consisting of the latissimus dorsi and teres major muscles. [8] It can descend after weight loss. [9] The anterior boundary is called the anterior axillary fold and this is rounded in shape and formed by the lower border of the pectoralis major.
