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.

Usted puede, a riesgo de afectar la calidad de su experiencia de usuario, cambiar las siguientes configuraciones: Anterior sternoclavicular Posterior sternoclavicular Interclavicular Costoclavicular. The humerus is flexed drawn forward by the Ligamentk major, anterior fibers of the Deltoideus, Coracobrachialis, and when the forearm is flexed, by the Biceps brachii; extended drawn backward by the Coracohumeeral dorsi, Teres major, posterior fibers of the Deltoideus, and, when the xoracohumeral is extended, by the 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.
There are usually three openings in the capsule. By rotating the humerus laterally, this contact is delayed because the greater tubercle is pulled logamento so that the bicipital groove faces the coracoacromial ligament.
In human anatomy, the corqcohumeral ligaments GHL are three ligaments on the anterior side of the glenohumeral joint i.

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.
The joint is protected above by an arch, formed by the coracoid process, the acromion, and the coracoacromial ligament. 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 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.

Articular capsule Glenoid labrum Glenohumeral ligaments Coracohumeral ligament Transverse humeral ligament 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.
Volume One Upper Limb 5th ed. 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 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 the 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.
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.
During abduction the greater tubercle of the humerus comes in contact with the upper margin of the glenoid cavity, which limits maximum abduction.
The Deltoideus covers the articulation in front, behind, and laterally. It’s a completely public and open space to all members of the Steemit community who voluntarily choose to be there. Views Read Edit View history. Bone loss in anterior instability.
