What type of nerves are responsible for sending sensory information to the brain?

Afferent nerves, also known as sensory nerves, play a crucial role in the nervous system by transmitting sensory information from various parts of the body to the brain. These nerves are specifically designed to carry signals related to sensations such as touch, pain, temperature, and pressure. When you touch something hot, for example, afferent nerves quickly send that sensory information to the brain, allowing for a rapid response.

Motor nerves, in contrast, are responsible for sending signals from the brain to muscles, facilitating movement rather than conveying sensory input. Mixed nerves contain both afferent and motor fibers, meaning they can transmit both sensory information to the brain and motor commands from the brain to the muscles. Autonomic nerves control involuntary functions within the body, like heart rate and digestion, but do not primarily handle sensory information in the same way that afferent nerves do. Thus, afferent nerves are specifically tasked with sensory communication, making them the correct choice in this scenario.
