Sensory neurons send signals in the form of action potentials to the central nervous system (CNS), which includes the brain and spinal cord. The CNS processes these signals and determines the appropriate response. If the response involves movement, the CNS sends signals to the motor neurons, which are responsible for controlling the movement of muscles. The motor neurons in turn send signals in the form of action potentials to the muscles, causing them to contract and produce movement. Therefore, sensory neurons reach motor neurons indirectly through the CNS.
