The glenohumeral joint that articulates the humerus to the pectoral girdle is a highly mobile joint. This mobility comes at a cost because .

the joint is relatively unstable and can easily dislocate

Explanation:

The glenohumeral joint is a ball and socket type of joint and it is found between the scapula and the humerus. The ball and socket joint helps in its ability to perform rotational movement.

The glenohumeral joint that articulates the humerus to the pectoral girdle is a highly mobile joint. This mobility comes at a cost because the joint is relatively unstable and can easily dislocate.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
