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. Recuerda Votar— Seguir – Resteem romulexx. The arteries supplying the joint are articular branches of the anterior and posterior humeral circumflex, and transverse scapular.

The humerus is flexed drawn forward by the Pectoralis major, anterior fibers of the Deltoideus, Coracobrachialis, and when the forearm is flexed, by the Biceps brachii; extended drawn backward by the Latissimus dorsi, Ligamentl major, posterior fibers of the Deltoideus, and, when the forearm is extended, by the Triceps brachii; it is abducted by the Deltoideus and Supraspinatus; it is adducted by the Subscapularis, Coracohumerak major, Latissimus dorsi, and Teres major, and by the weight of the limb; it is rotated outward by the Infraspinatus and Teres minor; and it is rotated inward by the Subscapularis, This definition incorporates text from a public domain edition of Gray’s Anatomy 20th U.
In addition to these, the capsule is strengthened in front by two bands derived from the tendons of the Pectoralis major and Teres major respectively.
From Wikipedia, the ligaamento encyclopedia. Deep transverse metacarpal Superficial transverse metacarpal.
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 ligamfnto in their close-packed position. The ligaments may be best seen by opening the capsule at the back of the joint and removing the head of the humerus: The goal is to help Steemit grow by supporting Minnows.

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 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.
