What type of nerve fibers in the skin are responsible for responding to touch?

1. Motor nerves

2. Autonomic nerves

3. Sensory nerves

4. Mixed nerves

The correct answer is: Sensory nerves

Sensory nerves are indeed the correct answer as they are specifically responsible for detecting and transmitting sensory information, including touch, from the skin to the central nervous system. These specialized fibers respond to various stimuli, such as pressure and vibration, allowing us to perceive tactile sensations. Motor nerves, on the other hand, are responsible for carrying signals from the central nervous system to muscles, enabling movement, while autonomic nerves control involuntary bodily functions, such as heart rate and digestion. Mixed nerves contain both sensory and motor fibers, but they do not solely focus on the sensation of touch. Therefore, sensory nerves are uniquely equipped to relay the tactile information from the skin, making them the appropriate choice for this question.
