Anatomical Relations
The glenohumeral ligaments include the superior, middle, and inferior ligaments.
The middle glenohumeral ligament arises from its wide attachment along the anterior glenoid margin, just below the attachment of the superior glenohumeral ligament. It extends laterally and inferiorly to the lesser tubercle of the humerus, deep to the tendon of the subscapularis muscle, with which its fibers blend.

Structure
The glenohumeral ligaments are fibrous bands and are only truly evident from within the joint.
Function
The middle glenohumeral ligament reinforces the articular capsule of the glenohumeral joint, particularly the anterior portion of the capsule. Additionally, it provides anterior stability to the head of the humerus during abduction between 45° and 60° in the scapular plane.
