Sensory neurons play a crucial role in the nervous system by transmitting signals from the peripheral nervous system to the central nervous system (CNS). They are responsible for collecting information from sensory receptors located throughout the body, which detect various stimuli such as touch, pain, temperature, and environmental changes. Once these stimuli are detected, sensory neurons carry the information in the form of electrical impulses to the CNS, where the signals can be processed and interpreted.

This function is vital for allowing the body to react to changes in the environment and for facilitating sensations that are important for survival and interaction with the world. By accurately sending sensory information to the brain and spinal cord, these neurons enable the body to perceive sensations and respond appropriately.
