Infraspinatus insertion and origin.
Teres major muscle. 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 infraspinatus muscle has its origin in the infraspinous fossa of the scapula and inserts into the middle facet of the greater tuberosity of the humerus (see Fig. 42-1).
