What process converts a noxious stimulus, like intense heat, into an electrical signal at the peripheral nerve endings?

Answer

Transduction

Transduction is the specific stage where specialized sensors, nociceptors, convert damaging stimuli such as heat, cold, pressure, or chemical irritants into an electrical signal that can travel to the central nervous system.
