Sensory nerves that detect temperature are commonly known as which type of nerve?

• A. Motor nerves
• B. Sympathetic nerves
• C. Sensory nerves
• D. Autonomic nerves

Answer: (C)

Sensory nerves are specifically designed to carry information from sensory receptors to the central nervous system. In the context of temperature detection in the skin, these sensory nerves are responsible for transmitting signals regarding thermal changes, such as heat and cold. This ability enables the body to respond appropriately to environmental changes and maintain homeostasis.

Sensory nerves play a crucial role in the somatosensory system, which encompasses the senses responsible for detecting physical stimuli. This includes not only temperature but also touch, pain, and pressure. The presence of specialized thermoreceptors in the skin allows these sensory nerves to effectively relay temperature information, leading to sensations that can trigger reflex actions or conscious perception of temperature changes.

In contrast, motor nerves are involved in transmitting signals from the brain to muscles, facilitating movement. Sympathetic and autonomic nerves pertain to the regulation of involuntary bodily functions, such as heart rate and digestion, rather than the direct sensation of temperature. Thus, the designation of sensory nerves as the correct answer aligns perfectly with their role in temperature perception.
