Function.

  • Concentric action: pronates forearm at radioulnar joints and weakly flexes forearm at elbow joint.
  • Reverse mover action: pronation of forearm; elbow flexion.
  • Eccentric action: controls/restrains/slows elbow supination and elbow extension.
  • Isometric action: stabilization of the elbow.
  • Innervation: median nerve.
