Teres major muscle (Musculus teres major) The teres major is a thick muscle of the shoulder joint. It spans from the inferior aspect of the scapula to the proximal part of the humeral shaft. Unlike the teres minor, the teres major muscle does not attach to the capsule of the glenohumeral joint. Thus it is not regarded as part of the rotator. The teres major is a thick but flattened, rectangular muscle that extends from the inferior posterior scapula to the medial lip of the intertubercular groove of the humerus.[1][2] It functions synergistically with the latissimus dorsi to extend, adduct, and internally rotate the humerus.[3] Although the latissimus dorsi and teres major muscles often function in conjunction with one another.
