What are the three nerves involved in a reflex?

The three nerves involved in a reflex are the sensory (afferent) nerve, the motor (efferent) nerve, and the interneuron. The sensory nerve transmits the signal from the sensory receptor to the spinal cord, where the interneuron processes the information and relays it to the motor nerve. The motor nerve then sends a signal from the spinal cord to the muscle, causing a response. This pathway allows for a quick, involuntary reaction to stimuli.
