Quizplus · Accepted Answer

Pain information travels to the brain along A-delta fibers, which transmit sharp and fast pain, and C fibers, which transmit dull and slow pain. Alpha-alpha and alpha-beta fibers are involved in proprioception and touch information, while C fibers are not the only type of fiber involved in pain transmission.
