Flexors are the muscles that flex a joint. A wrist and the adjoining fingers have multiple muscles that work together to bring about complex movements. Flexor muscles are found at the front side of the forearm. Flexor muscles help flex the wrist. A few of them are: flexor digiti, flexor retinaculum, etc. These muscles emerge from the humerus of the upper arm. The main function of wrist flexors is to bend the wrist towards the arm, while that of the finger flexors is to make a fist.
