Question

what combination of movements can occur at the glenohumeral joint besides rotation? gliding and rolling abduction and adduction protraction and retraction flexion and extension

Explanation:

The glenohumeral (shoulder) joint is a ball-and-socket joint. Rotation is one of its movements, and it also performs flexion (forward movement) and extension (backward movement), along with abduction/adduction. However, the question asks for a combination besides rotation, and flexion and extension are primary, distinct movement pairs for this joint. Gliding/rolling are accessory movements, while protraction/retraction occur at the sternoclavicular/acromioclavicular joints, not the glenohumeral joint.

Answer:

Flexion and extension
