3 lis 2023 · Palmaris longus muscle originates from the medial epicondyle of humerus, via the common flexor origin. A tendinous hub that it shares with the five long forearm flexors; flexor carpi radialis, flexor carpi ulnaris, pronator teres, flexor digitorum superficialis and profundus.
11 lip 2024 · The palmaris longus originates from the medial epicondyle of the humerus, a bony prominence on the inner aspect of the elbow. From this origin point, the muscle courses through the forearm, lying superficially between the flexor carpi radialis and the flexor carpi ulnaris muscles.
Palmaris longus is a slender, elongated, spindle shaped muscle, lying on the medial side of the flexor carpi radialis. It is widest in the middle, and narrowest at the proximal and distal attachments.
5 maj 2023 · Origin: Medial epicondyle of the humerus (the common flexor tendon) Insertion: Distal side of the flexor retinaculum, and the palmar aponeurosis
28 sie 2023 · The palmaris longus commonly sends a slip of distal tendon that inserts into the abductor pollicis brevis muscle of the thenar muscle group and may contribute to thumb abduction. Congenital absence of the palmaris longus does not affect grip or pinch strength contributed to by wrist flexion.
