Answer 1

The complete slipping of the ball of the humerus out of the scapula's socket is known as a shoulder dislocation.

Step-by-step explanation:

When the ball of the humerus slips completely out of the scapula's socket, what will occur is a B. Shoulder dislocation. This injury happens most commonly when the arm is fully abducted and a force is applied to it, such as when diving to catch a ball and landing on the hand or elbow. The support for the shoulder joint largely comes from the muscles whose tendons form the rotator cuff; however, when these support structures are overwhelmed by force, the humerus can become dislocated from the glenoid cavity of the scapula.
