Motor neurons transmit signals from the central nervous system to effector cells, such as muscles or glands, allowing for motor responses. Sensory neurons, on the other hand, convey signals from sensory receptors to the central nervous system, enabling sensory perception.

Option A is incorrect because it reverses the direction of signal transmission of sensory neurons.

Option C is incorrect because the peripheral nervous system consists of both nerves and ganglia.

Option D is incorrect because the CNS consists of the brain and spinal cord, which are anatomically and functionally distinct structures.
