| 1. | The greater tubercle projects as the most lateral structure of the humeral head.
|
| 2. | Tendinous fibers extend to the greater tubercle with insertions into the bicipital groove.
|
| 3. | The supraspinatus tendon is inserted into the superior facet of the greater tubercle of the humerus.
|
| 4. | The humerus of the upper arm has two tubercles, the greater tubercle and the lesser tubercle.
|
| 5. | Such a tear usually occurs at its point of insertion onto the humeral head at the greater tubercle.
|
| 6. | The supraspinatus muscle fans out in a horizontal band to insert on the superior and middle facets of the greater tubercle.
|
| 7. | The infraspinatus and teres minor insert on the greater tubercle, and work to laterally, or externally, rotate the humerus.
|
| 8. | This capsule is strengthened by the coracohumeral ligament which attaches the coracoid process of the scapula to the greater tubercle of the humerus.
|
| 9. | All three of the muscles that attach to the greater tubercle are part of the rotator cuff, a muscle group that stabilizes the shoulder joint.
|
| 10. | The fourth muscle of the rotator cuff ( the subscapularis ) does not attach to the greater tubercle, but instead attaches to the lesser tubercle.
