Sensory nerves are the type of nerves responsible for transmitting sensory information from various parts of the body to the brain. These nerves carry signals related to touch, pain, temperature, and other sensory modalities, allowing the brain to perceive and process information about the internal and external environment.

Each sensory nerve is designed to respond to specific types of stimuli. For example, they can be activated by tactile stimuli, thermal changes, or painful experiences. Once activated, sensory nerves relay this information through electrical impulses along their pathways to the central nervous system, where it can be interpreted and responded to.

While motor nerves control muscle movements and somatic nerves can encompass various nerves related to movement and sensation, it is the sensory nerves that specifically focus on conveying sensory experiences to the brain. Cranial nerves also have a role in sensory information processing, but they are part of a broader group that can also include motor functions. The distinction of sensory nerves lies in their exclusive function of transmitting sensory data.
