Web21 de jul. de 2012 · Slow pain, which starts immediately after the fast pain, is transmitted by very thin nerve fibers, called C-nerve fibers (their diameter is between 0.2 to 1 thousandth of a millimeter). Because of their small size, the pain impulse can only be transmitted slowly to the brain, at a speed of less than 2 meters per second.
