| Motor neurons | carries impulses from brain and spinal cord towards effectors |
| Interneurons | relays impulses from 1 neuron to another |
| Nerves | used for the transmission of impulses from 1 part of the body to another |
| Sensory nerve | composed of dendrites of sensory neurons |
| Motor nerve | composed of axons of motor neurons |
