By its proximal end, which is situated immediately above the glenoid cavity, but subjacent to the coraco-acromial ligament, it is attached to the lateral border of the root of the coracoid process, while its distal end is attached to the humeral neck close to the greater tubercle. This ligament forms a flattened band, having its posterior and inferior border fused with the articular capsule, but its anterior and superior margin presents a free edge, slightly raised above the level of the capsule. This structure is believed to represent that portion of the pectoralis minor to which reference has already been made in connexion with the coraco-acromial ligament (p. 320). The coraco-glenoid ligament is another accessory structure, which is not always present. It springs from the coracoid process along with the former ligament, and extends to the superior and posterior margin of the head of the scapula. Gleno-humeral Ligaments (Fig. 303).—If the articular capsule is opened from behind, and the head of the humerus removed, it will be seen that the longitudinal fibres of the anterior part of the fibrous stratum are specially developed in the form of thick flattened bands which extend from the anterior border of the glenoid cavity to the anterior aspect of the neck of the humerus. These gleno-humeral ligaments are three in number, and occupy the following positions : the Coraco- ^ Conoid clavicular V Trapezoid ^- ligament J Coraco-acromial ligament Coracoid process Superior gleno- humeral ligament Acromio- clavicular ligament. Bursal perforation in articular capsule Inferior gleno- humeral ligament Glenoid cavity Labrum glenoidale Fig. 303.—Capsular Ligament of Shoulder-Joint cut across and Humerus removed. superior is placed above the aperture in the front of the capsule ; the middle and inferior on the antero-inferior aspect of
