Which function of the nervous system that detects stimuli and sends a message in the form of impulses to the brain and spinal cord?

The function of the nervous system that detects stimuli and transmits messages in the form of impulses to the brain and spinal cord is known as sensory input. Sensory receptors gather information from the environment, such as light, sound, and touch, and convert these stimuli into electrical signals. These signals travel along sensory neurons to the central nervous system, where they are processed and interpreted. This process allows the body to respond appropriately to different stimuli.
