Which type of nerves in the skin react to temperature changes?

Sensory nerves are responsible for detecting and transmitting information about external stimuli, including temperature changes, to the brain. These nerves have specialized receptors that respond to various environmental factors such as heat and cold. When the skin is exposed to temperature changes, the sensory receptors in these nerves are activated and send signals to the central nervous system, where the brain processes this information and produces appropriate responses, such as adjusting the body’s temperature or prompting protective behaviors.

Motor nerves, on the other hand, are involved in transmitting signals from the brain to muscles, initiating movement rather than sensory perception. Interneurons primarily function within the brain and spinal cord to relay signals between sensory and motor nerves, playing a role in reflex actions but not directly in temperature sensation. Sympathetic nerves are part of the autonomic nervous system and are involved in involuntary responses, particularly in stress responses, but they do not directly detect temperature. Therefore, sensory nerves are specifically designed to react to temperature changes, making them the correct answer.
