Most modelers are used to extruding profile curves along a path curve, but many forget that you can do the same thing with polygonal faces. Try this out, create a curve, select the faces you want to follow that curve then open the Extrude Faces Option Box and make sure "use selected curve for extrusion" is selected. Set any other extrude options then apply.
In the this example a simple torso was created then the base faces of the arm were extruded along a path curve simulating the arm bend and distance. If you have history on, you can even modify the extrusion result by editing the CVs or EPs of the path curve.
