Which action is NOT a function of the latissimus dorsi muscle?

The latissimus dorsi muscle is primarily responsible for the actions of extending, adducting, and internally rotating the shoulder joint. Its anatomical position and alignment allow it to play significant roles in pulling movements and actions that require the arm to be moved closer to the body or pulled downwards along the side.

When considering the action of abduction, which is the movement of the arm away from the body in the coronal plane, this does not align with the primary functions of the latissimus dorsi. Instead, muscles such as the deltoid and supraspinatus are primarily responsible for abducting the shoulder. Therefore, identifying abduction as not being a function of the latissimus dorsi is accurate, as this muscle is not involved in this particular action.
