The coracoacromial ligament is a flat triangular band that plays a supportive role for the shoulder joint.

The radius of curvature of the head of the humerus is greater superiorly than inferiorly, which further stretches these ligaments so that they keep the articular surfaces of the joint in their close-packed position. During abduction of the arm the middle and inferior ligaments liyamento taut while the superior ligament relaxes.

During rotation of the arm lateral rotation stretches all three ligaments while medial rotation relaxes them. By rotating the humerus laterally, this contact is delayed because the greater tubercle is pulled back so that the bicipital groove faces the coracoacromial ligament.

The Deltoideus covers the articulation in front, behind, and laterally. The tendon of the long head of the Biceps brachii passes through the capsule and is enclosed in a tubular sheath of synovial membrane, which is reflected upon it from the summit of the glenoid cavity and is continued around the tendon into the intertubercular groove as far as the surgical neck of the humerus.

The articular cartilage on the head of the humerus is thicker at the center than at the circumference, the reverse being the case with the articular cartilage of the glenoid cavity.

The ligaments do not maintain the joint surfaces in apposition, because when they alone remain the humerus can be separated to a considerable extent from the glenoid cavity; their use, therefore, is to limit the amount of movement.


The third is between the tubercles of the humerus, for the passage of the long tendon of the Biceps brachii. From Wikipedia, the free encyclopedia. No vale pero esto esta demasiado bueno!! It is strengthened, above, by the Supraspinatus; below, by the long head of the Triceps brachii; behind, by the tendons of the Infraspinatus and Teres minor; and ligametno front, by coracohumerwl tendon of the Subscapularis.

Palmer W, Caslowitz P. The bones entering into its formation are the hemispherical head of the humerus and the shallow glenoid cavity of the scapula, an arrangement which permits of very considerable movement, while the joint itself is protected against displacement by the tendons which surround it.

The muscles in relation with the joint are, above, the Supraspinatus; below, the long head of the Triceps brachii; in front, the Subscapularis; behind, the Infraspinatus and Teres minor; within, the tendon of the long head of the Biceps brachii. Anatomical terminology [ edit on Wikidata ligamenot.
