Examples of glenoid in the following topics:

  • Scapula

    • The scapula also articulates with the humerus of the upper arm to form the shoulder joint, or glenohumeral joint, at the glenoid cavity.
    • The lateral border is the thickest border of the scapula and extends downwards from the glenoid cavity.
    • Immediately below the glenoid cavity is the infraglenoid tuberosity, which is the origin for the long head of the triceps brachii.
    • Immediately above the glenoid cavity is the supraglenoid tubercle and its associated hook-like coracoid process, from which the long and short heads of the biceps brachii originate.

  • Humerus (The Upper Arm)

    • The rounded humeral head projects medially and articulates with the glenoid cavity of the scapula.

  • Rotator Cuff Injury and Dislocated and Separated Shoulder

    • Doctors treat a dislocation by putting the head of the humerus back into the joint socket (glenoid fossa) of the scapula.
