Answer 1

Answer:

The glenohumeral joint is more mobile, making it less stable. (Ans. C)

Explanation:

Shoulder joint is composed of three bones shoulder blade (scapula), collarbone (clavicle), and upper arm bone (humerus) Shoulder joint or glenohumeral joint is classified as a socket joint and synovial ball structurally and functionally divides as a multiaxial joint and diarthrosis.
