| Sensory Input | electrical impulse sent from the sensory organs |
| Integration | Processes and interprets information recieved through the sensory organs |
| Motor Output | Transmit messages to effectors |
| Parts of the brain | Frontal , Parietal, Occipital, Temporal |
| CNS VS PNS | Cns recieves, processes, and responds to the impulses Pns is the nerves outside |
