ABDUCTOR LONGUS POLLICIS Meaning and
Definition
-
The abductor longus pollicis is a specific muscle located in the base of the thumb. It is widely known as one of the major muscles responsible for thumb movement in the human hand.
This muscle belongs to the abductor pollicis group and is situated on the lateral side of the forearm. It originates from the posterior surface of the radius and ulna bones, as well as from the interosseous membrane between these bones. From there, it extends to the base of the first metacarpal bone of the thumb.
The primary function of the abductor longus pollicis muscle is to abduct the thumb, meaning it moves the thumb away from the hand into a more "hitchhiking" position. This muscle plays a crucial role in various activities involving thumb movement, such as gripping, grasping, and pinching. It works in coordination with other muscles to ensure proper thumb abduction functionality.
Injuries or conditions affecting the abductor longus pollicis muscle can result in limitations or difficulty with thumb abduction. These conditions may include strains, tears, or nerve impingements. Proper diagnosis and treatment are necessary to restore normal thumb movement and function. Rehabilitation exercises and physical therapy can be helpful in the recovery process.
