Flexors

The flexor carpi radialis (flek'sor kar-pi'ra"de-a'lis) is a fleshy muscle that runs medially on the anterior side of the forearm. It extends from the distal end of the humerus into the hand, where it is attached to metacarpal bones. The flexor carpi radialis flexes and abducts the hand at the wrist (fig. 9.30).

The flexor carpi ulnaris (flek'sor kar-pi' ul-na'ris) is located along the medial border of the forearm. It con nects the distal end of the humerus and the proximal end of the ulna to carpal and metacarpal bones. It flexes and adducts the hand at the wrist (fig. 9.30).

The palmaris longus (pal-ma'ris long'gus) is a slender muscle located on the medial side of the forearm between the flexor carpi radialis and the flexor carpi ulnaris. It connects the distal end of the humerus to fascia of the palm and flexes the hand at the wrist (fig. 9.30).
