Abductor Pollicis Longus Muscle

The abductor pollicis longus muscle is a long, thin muscle of the forearm that serves to pull the thumb away from the palm. Abduction refers to movement of a limb away from the central line of the body or of a digit away from the axis of a limb. Muscles, then, that carry out this type of movement are called abductor muscles.
