This muscle arises from the flexor side of the humerus, distal to the 

 crista ventralis humeri^ and runs parallel with the bone, converging 

 slightly towards its distal end. Its insertion on the proximal end of 

 the radius is inclined to become tendinous. 



Innervation-. It is supplied by one or two branches from the R. 

 superficialis N. brachialis. 



Function-. It is the true flexor muscle of the elbow.

 These should be dissected from the dorsal side.

 covering the extensor surface of the fore-arm and wrist. Distally it
