Webb11 sep. 2016 · You judge a wide range of temperatures (cool, damp, chilly, cold, warm, humid, hot, and so on) by sensing the unique ratio of activation of the different receptors activated at any particular temperature. Extreme heat, cold or skin pressure, however, activates receptors that are interpreted as pain. WebbThermoreceptors. Thermoreceptors can be separated into receptors for warmth and cold detection. According to results of differential nerve blocks and response latencies, the warmth sensation has been attributed to C fibers, whereas cold detection is a function of Aδ fibers.15,105 Microneurographic recordings from Aδ fibers are sparse, and so ...
