3 lis 2023 · Flexor carpi radialis originates from the medial epicondyle of humerus, via the common flexor tendon, and surrounding fascia (antebrachial fascia and intermuscular septa). This common flexor tendon is a common origin for the six long flexor muscles in the forearm; flexor carpi radialis, palmaris longus, flexor carpi ulnaris, pronator teres ...

2 lis 2023 · The flexor digitorum superficialis is the largest muscle of the superficial anterior forearm muscles. It consists of two heads that are named according to their origins. The humeroulnar head originates from the medial epicondyle of humerus and the coronoid process of ulna, while the radial head originates from the shaft of radius. The muscle ...
8 paź 2024 · The muscle splits into four tendons at the wrist, which travel through the carpal tunnel, and attach to the base of the middle phalanx of the four digits. Actions: Flexes the metacarpophalangeal joints and proximal interphalangeal joints at the 4 fingers, and flexes at the wrist.
28 lis 2023 · Extending from the wrist to the elbow joint is the region of the upper extremity called the forearm (antebrachium). The forearm helps the shoulder and the arm in force application and the precise placement of the hand in space, with the help of the elbow and radioulnar joints.
The Anterior (Flexor) Compartment of the Forearm. The anterior compartment contains all the flexors of the forearm, hand, and fingers. These are further divided into three groups: superficial, intermediate, and deep flexors. Superficial Flexors. Pronator teres; Flexor carpi radialis; Palmaris longus; Flexor carpi ulnaris
Flexor pollicis longus (FPL) tendon. The FPL tendon bends the thumb. It is unique to humans. It starts as a muscle in the forearm and then travels as a tendon in the wrist through the carpal tunnel. It is then covered by a tunnel, or sheath, and inserts into the most distal (farthest from your body) bone in the thumb.
Flexor Digitorum Superficialis: Lying below the superficial region, the flexor digitorum superficialis is a key muscle controlling wrist and finger flex. Attachments: Originates from the humerus and the radius, splitting into four tendons at the wrist which travel through the carpal tunnel and attach to the fingers.
