2. Looseness of its articular capsule
3. The shallowness of the glenoid cavity
4. The relatively large head of the humerus
Work Step by Step

However the shoulder joint has more freedom of movement that even the hip joint. The shoulder joint allows, flexion, extension, hyper-extension, medial rotation, lateral rotation, and circumduction.
