What is 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? and explain in detail?
A delta nerve fiber is involved in transmitting pain and temperature in the body. It's conduction velocity is 12-30 m/s. A alpha fiber is involved in carrying proprioception and somato motor sensation. It's conduction velocity is 70-120 m/s. A beta fiber is involved in carrying touch and pressure sensation. It's conduction velocity is 30- 70m/s. A gamma acts as motor to the muscle spindle. It's conduction velocity is 15 - 30m/s. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 4.
