What type of nerves are responsible for detecting heat?

Sensory nerves play a crucial role in the nervous system by transmitting information from sensory receptors to the central nervous system. These nerves are specifically designed to detect various stimuli, including heat, touch, pain, and pressure. When heat is present, thermoreceptors, which are specific types of sensory receptors, detect this change in temperature and send signals through sensory nerves to the brain, allowing it to interpret and respond to the sensation of heat.

In contrast, motor nerves are responsible for conveying signals from the central nervous system to muscles, triggering movement. Autonomic nerves, while essential for regulating involuntary body functions such as heart rate and digestion, do not handle sensory input. Mixed nerves contain both sensory and motor fibers, but they also encompass a broader range of functions beyond just heat detection. Therefore, sensory nerves stand out as the specific type that is dedicated to detecting heat and other sensory information.
