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 cuff muscles. The teres major is a medial rotator and adductor of the humerus and assists the latissimus dorsi in drawing the previously raised humerus downwards and backwards ( extension, but not hyperextension ). It also helps stabilise the humeral head in the glenoid cavity . Injury Isolated teres major injuries are rare.
Anatomy of the Teres Major —
Introduction Teres major (TM) is a small muscle that runs along the lateral border of the scapula. It is one of the seven scapulohumeral muscles that act around the glenohumeral joint to facilitate shoulder movement [1]. [2] It's sometimes called "lat's little helper" because of its synergistic action with the latissimus dorsi. [3] 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] Teres major muscle is one of the seven scapulohumeral muscles that act around the glenohumeral joint to facilitate shoulder movement. Summary origin: caudal two thirds of lateral border and inferior angle of scapula insertion: medial border of the intertubercular groove, which is the crest of lesser tubercle of humerus The teres major is an intrinsic muscle of the shoulder region. It forms the inferior border of the quadrangular space - the space that the axillary nerve and posterior circumflex humeral artery pass through to reach the posterior scapular region. Attachments: Originates from the posterior surface of the inferior angle of the scapula.

The teres major muscle originates from the posterior aspect of the inferior angle of the scapula and its adjacent area. Insertion The fibers of the teres major muscle travel superolaterally and insert, via a flat tendon, onto the crest of the lesser tubercle of the humerus. Nerve Supply and Blood Supply:. The teres major muscle is innervated by the lower subscapular nerve (C5-C7) from the posterior cord of the brachial plexus. It receives its blood supply primarily from branches of the subscapular artery.. Teres Major Anatomy Palpation. Palpating the teres major is an essential technique for clinicians to assess its condition and identify potential issues. Description: The Teres major is a thick but somewhat flattened muscle, which arises from the oval area on the dorsal surface of the inferior angle of the scapula, and from the fibrous septa interposed between the muscle and the Teres minor and Infraspinatus; the fibers are directed upward and lateralward, and end in a flat tendon, about 5 cm. a to d The anterior view of the humerus after the deltopectoral approach and resection of the pectoralis major tendon.

Dr. Ebraheim's educational animated video describes how to do examination for the teres major muscle.Follow me on twitter:https://twitter.com/#!/DrEbraheim_U. If your teres major is overactive/short, do the following: Reduce your training volume on teres major exercises and lat exercises. If your overhead range of motion is limited, avoid vertical push exercises like the overhead press. Do high-incline push exercises instead (e.g. shoulder press on 60-75° incline).
The function of Teres Major Muscle. The primary function of teres major is to create the movements of the humerus at the glenohumeral joint; it pulls the anterior surface of the humerus medially towards the trunk (internal rotation). Furthermore, it can also extend the arm from the flexed position. Teres Major is one of the four rotator cuff muscle located at the upper back region of the shoulder; it connects the shoulder blade to the upper arm. The teres major muscle is an important muscle as it is responsible for a number of shoulder movements in multiple directions.

From the insertion of the triceps brachii (Fig. 7 c) the teres major muscle and the latissimus dorsi are behind the triceps (Fig. 7 d) and at the end of the sequence the teres major muscle is deformed by the pressure the humeral head is putting on it (Fig. 7 e and f).

It is one of the four muscles of the rotator cuff, along with the supraspinatus, infraspinatus and subscapularis .
