Explanation:
Detailed explanation-1: -Changes in environmental temperature are detected by thermoreceptors localized in cutaneous endings of primary somatosensory nerve fibers (see Chapter 2). The transient receptor potential (TRP) family of cation channels has been identified as the molecular entities of cold and warmth receptors (see Chapters 3 and 4).
Detailed explanation-2: -A classical model of the sensory system states that thermoreceptors (e.g., thermoTRPs) in skin nerve endings are sensors that transform temperature into the firing rate codes that are sent to the brain, where the codes are decoded as “cold” by a labeled line theory.
