Final answer:
The glenohumeral joint is a ball-and-socket joint that allows for a wide range of motion due to its loose articular capsule and muscular support, particularly from the rotator cuff. This results in a lower level of bony or ligamentous stability compared to other joints. The correct option is C.
Step-by-step explanation:
The glenohumeral joint, also known as the shoulder joint, is a ball-and-socket joint that enables a wide range of motion. This joint is unique in that the articulation between the head of the humerus and the relatively small glenoid cavity of the scapula allows for multidirectional movements such as flexion/extension, abduction/adduction, circumduction, and medial/lateral rotation.
However, this extensive mobility comes at the cost of stability. The joint has a loose articular capsule and is largely supported by surrounding muscles, specifically the rotator cuff, rather than bony structures or tight ligaments.
Therefore, between the options provided, the best answer is: c) A low level of stability but a wide range of motion.
