Origins, Insertion, Innervation and Functions of the flexor pollicis longus muscle and more in

Flexor pollicis longus, as its name suggests, is a long muscle of the forearm. It belongs to the deep flexors of the forearm, along with flexor digitorum profundus and pronator quadratus. Since it lies in the forearm but inserts in the hand, flexor pollicis longus is also classified as an extrinsic muscle of the hand.

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.

Flexor Pollicis Longus Learn Muscles

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.

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 ( / 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]

The flexor pollicis longus muscle is one of the muscles of the deep part of the anterior compartment of the forearm. It is a unipennate type of skeletal muscle. At the wrist, its tendon travels deep to the flexor retinaculum of hand, where it passes through the tendinous sheath of flexor pollicis longus.

The flexor pollicis longus (FPL) is a long muscle located at the deep layer with flexor digitorum profundus and pronator quadratus in the anterior compartment of the forearm. The tendon goes through the carpal tunnel and inserts on the distal phalanx of the thumb. It is the primary flexor to bend the tip of the thumb (flexion of distal

A square shaped muscle found deep to the tendons of the flexor digitorum profundus and flexor pollicis longus. Attachments: Originates from the anterior surface of the ulna and attaches to the anterior surface of the radius. Actions: Pronates the forearm. Innervation: Median nerve (anterior interosseous branch).

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.

muscle that extends the thumb

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.
