A woodworker operating a bandsaw accidently injures his wrist, severing his radial artery and producing severe hemorrhage. As he loses blood, his body tries to compensate for the developing hypotension by increasing sympathetic outflow. The postganglionic signals carrying the impulses to constrict his arterioles are transmitted along which of the following fiber types?
(A) A-δ fibers
(B) B fibers
(C) C fibers
(D) Ia fibers
(E) Ib fibers
