<prompt> A person is able to sense pain and temperature normally. Which of the following type of nerve fiber is involved in carrying pain and temperature?A alphaA betaA gammaA delta  <response>: A delta nerve fiber is involved in transmitting pain and temperature in the body. Its conduction velocity is 12-30 ms. A alpha fiber is involved in carrying proprioception and somato motor sensation. Its conduction velocity is 70-120 ms. A beta fiber is involved in carrying touch and pressure sensation. Its conduction velocity is 30- 70ms. A gamma acts as motor to the muscle spindle. Its conduction velocity is 15 - 30ms.
