Question

the whole deltoid muscle ______ the humerus. flexes pronates rotates inverts abducts

Explanation:

The deltoid muscle is located on the shoulder. Its main function is to move the arm away from the body, which is called abduction. Flexion (bending) is more associated with muscles like biceps for the arm in a different context. Pronation (rotating the forearm so the palm faces down) is done by other forearm - related muscles. Rotation (internal/external rotation of the arm) has more specific rotator cuff muscles (though the deltoid can assist in some rotation, its primary function is abduction). Inversion is a movement related to the foot (turning the sole inward).

Answer:

abducts
