Abstract: 

The present study was conducted in the Department of Physiology, Netaji Subhash Chandra Bose Medical College and Hospital, Jabalpur (M.P.) . Median motor and sensory nerves were examined in 60 medical students aged between 17-25 years, having no signs or symptoms of neurological impairment. Using surface and ring electrodes. Different temperature i.e. hot and cold were maintained with the help of water bath and skin temperature measured by using Digital Mercury Thermometer. The result of our study showed that as the temperature is decreased gradually from normal body temperature 370 C to 290C, latency of median motor and sensory nerve increased by 0.18 to 0.24 millisecond/0C.The amplitude of median motor and sensory nerve were found increased on decreasing temperature from normal body temperature 370 C to 290C, but this increase was found statistically insignificant
