Attachments and Actions of the Flexor Pollicis Longus. The flexor pollicis longus is a muscle of the anterior forearm and hand. Its principal attachments are from the anterior surface of the radius to the anterior surface of the distal phalanx of the thumb. It usually also has a small attachment to the medial epicondyle of the humerus (Figure 4) (Note: the common flexor belly/tendon of muscles.

Structure and Function The FPL muscle is the primary flexor of the thumb, providing flexion at its metacarpophalangeal (MCP) joint and interphalangeal (IP) joint. Additionally, FPL has minor contributions in radial wrist deviation and wrist flexion. [1]

Flexor Pollicis Longus Learn Muscles

The flexor pollicis longus is one of three muscles in the deep compartment of the anterior muscles of the forearm. The two other muscles are the flexor digitorum profundus and the pronator quadratus. The name in Latin translates as the long flexor of the thumb.

The FPL mainly flexes interphalangeal joint of the distal phalanx of the thumb. It also serves as accessory flexors of the metacarpophalangeal of the proximal phalanx and carpometacarpal joints of the first metacarpal. It may also assist in wrist joint flexion.

Flexor pollicis longus is used for tasks requiring gripping of the hand such as grasping or lifting an object. Any injury to the muscle will cause a decrease in the flexion ability of the thumb which can be a frustrating and debilitating injury. Flexor pollicis longus is susceptible to muscle tears, muscle strain, tendonitis, and rupture.

The flexor pollicis longus (Latin: musculus flexor pollicis longus) is a long muscle of the upper limb that stretches between the radius and the distal phalanx of the thumb. It is one of the deep muscles of the forearm that is located in the anterior compartment. Together with the flexor digitorum profundus, this deep flexor of the forearm lies in the third muscle layer.

The flexor pollicis longus muscle inserts on the thumb at the distal phalanx. The flexor digitorum profundus muscle originates from the proximal end of the radius and ulnar. The flexor digitorum profundus muscle descends to attach at the base of distal phalanx of the second, third, fourth, and fifth digits.

The flexor pollicis longus ( / ˈflɛksər ˈpɒlɪsɪs ˈlɒŋɡəs /; FPL, Latin flexor, bender; pollicis, of the thumb; longus, long) is a muscle in the forearm and hand that flexes the thumb. It lies in the same plane as the flexor digitorum profundus. This muscle is unique to humans, being either rudimentary or absent in other primates. [1]

Anatomy of the Flexor Pollicis Longus —

The Flexor pollicis longus is situated on the radial side of the forearm, lying in the same plane as the preceding. It arises from the grooved volar surface of the body of the radius, extending from immediately below the tuberosity and oblique line to within a short distance of the Pronator quadratus. It arises also from the adjacent part of.
