The coracoacromial ligament is a flat triangular band that plays a supportive role for the shoulder joint. The coracoacromial arch is formed (anteriorly to posteriorly) by the coracoid process, coracoacromial ligament, and acromion. It is thought that decreased space within the.

Coracoacromial Superior transverse scapular Inferior transverse of scapula Synovial: There are usually three openings in the capsule. From Wikipedia, the free encyclopedia.
The Deltoideus covers the articulation in front, behind, and laterally. The coraochumeral may be best seen by opening the capsule at the back of the joint and removing the head of the humerus: Views Read Edit View history. Your post was upvoted by utopian. 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.
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, Teres major, posterior fibers of the Deltoideus, and, when the forearm is extended, by liigamento Triceps brachii; it is abducted by the Deltoideus and Supraspinatus; it is adducted by the Subscapularis, Pectoralis 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.
The articular capsule completely encircles the joint, being attached, above, to the circumference of the glenoid cavity beyond the glenoidal labrum; below, to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent. During abduction the greater tubercle of the humerus comes in contact with the upper margin of the glenoid cavity, which limits maximum abduction.

It is thicker above and below than elsewhere, and is so remarkably loose and lax, that it has no action in keeping the bones in contact, but allows them to be separated from each other more than 2. In human anatomy, the glenohumeral ligaments GHL are three ligaments on the anterior side of the glenohumeral joint i. The tendon thus traverses the articulation, but it is not contained within the synovial cavity.

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. Capsule Coracohumeral Glenohumeral superior, middle, and inferior Transverse humeral Glenoid labrum. Anular Oblique cord Quadrate. The Physiology of the Joints: 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 become taut while the superior ligament relaxes. Reinforcing the anterior glenohumeral joint capsule, the superior, middle, and inferior glenohumeral ligaments play different roles in the stability of the head of the humerus depending on arm position and degree of rotation. No vale pero esto esta demasiado bueno!! Acromioclavicular Coracoclavicular trapezoid conoid.
One anteriorly, below the coracoid process, establishes a communication between the joint and a bursa beneath the tendon of the Subscapularis. The ,igamento 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 second, which is coracohumera, constant, is at the posterior part, where an opening sometimes exists between the joint and a bursal sac under the tendon of the Infraspinatus. 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.
