Head |
Semi-rounded proximal end; articulates with the scapula |
|
|
Surgical neck |
Slightly constricted area just below tubrecles where the head meets the body |
|
|
Anatomical Neck |
Circumferential groove separating the head from the tubercle |
|
|
Greater Tubercle |
Large projection lateral to head and lesser tubercles; provides attachment for the supraspinatus, infraspinatus, and teres minor muscles
|
|
|
Lesser Tubercle |
Smaller projection on the anterior surface, medial to the greater tubercle; provides attachment for the subscapularis muscle |
|
|
Deltoid Tuberosity |
On the lateral side near the midpoint, not usually a well-defined landmark |
|
|
Deltoid |
A superficial muscle that covers the shoulder joint on three sides, giving the shoulder its rounded shape |
|
|
Deltoid (Anterior) |
Attaches to the outer third of the clavicle and runs down and out to the deltoid tuberosity, which is located on the lateral aspect of the humerus near the midpoint |
|
|
Deltoid (Middle) |
Attaches on the lateral side of the acromion process and runs directly down to the deltoid tuberosity |
|
|
Deltoid (Posterior) |
Attaches to the spine of the scapula and runs obliquely down to its attachment with the anterior and middle fibers on the deltoid tuberosity |
|
|
Pec Major (Clavicular) |
Attaches to the medial third of the clavicle |
|
|
Pec Major (Sternal) |
Attaches to the sternum and costal cartilages of the first six ribs |
|
|
Latissumus Doris Muscle |
A broad, sheetlike muscle located on the back |
|
|
Teres Major |
Has its proximal attachment on the axillary border of the scapula, just below the teres minor muscle |
|
|
Supraspinatus |
Lies above the spine of the scapula |
|
|
Infraspinatus |
Lies below the spine of the scapula |
|
|
Teres Minor |
Closely related to the infraspinatus muscle in both anatomical location and function |
|
|
Subscapularis |
Located on the deep underside of the scapula, lying next to the rib cage |
|
|
Coracobrachialis |
Derives its name from its attachments on the coracoid process of the scapula and on the humerus or arm |
