Explain why injuries involving the shoulder joint are common
What will be an ideal response?
The mobility of the shoulder joint comes at the expense of stability and increased risk of injury. The shoulder joint is a ball-and-socket joint in which the ball-shaped head of the humerus articulates with the shallow glenoid cavity of the scapula. This joint receives support and stability from a number of surrounding structures (like the rotator cuff), but the shoulder can still become dislocated or separated.
