Flexor
Definition:
(n.) A muscle which bends or flexes any part; as, the flexors of the arm or the hand; -- opposed to extensor.

(4) Tension in flexor tendons during wrist flexion may play a role in otherwise unexplained instances of the carpal tunnel syndrome.
(5) Weakness of the flexor pollicis longus, flexor digitorum profundus and pronator quadratus is usually related to an isolated paralysis of the anterior interosseous nerve in the volar aspect of the forearm.
(6) There were no significant effects of training on the time-related contractile properties (time to peak torque, half-relaxation time), CSA, or %MUA of the elbow flexors or knee extensors.
(7) The aim was to find out to what extent information from homonymous muscles of the forelimbs converge on the same CBM neurons and whether the probability of such a convergence depends on location (axial, proximal, distal) or function (flexor, extensor) of the tested muscles.
