The glenoid labrum can become torn from overuse or direct injury to the shoulder joint. Considering the function of the glenoid labrum, describe some of the consequences of a large tear in the glenoid labrum.

-Tears in the glenoid labrum could lead to decreased range of motion at the elbow because the biceps brachii tendon attaches to the glenoid labrum. -Tears in the glenoid labrum can lead to shoulder dislocation because the glenoid cavity is very shallow without the glenoid labrum to stabilize the humerus. -"Popping" or "catching" of the shoulder can result because a torn glenoid labrum is unable to hold the humerus tightly against the glenoid cavity. -All of the answers are correct.
