PALMARIS LONGUS

The palmaris longus is a short, narrow muscle that originates from the medial epicondyle of the humerus and converges into a long, slender, slightly flattened tendon that inserts in the flexor retinaculum of the wrist. It is innervated by the median nerve and supplied by the ulnar artery. This muscle bends the hand at the wrist.
