| The division of the nervous system consisting of the brain and spinal cord. | central nervous system |
| An action or change in behavior that occurs in reaction to a stimulus. | response |
| The division of the nervous system consisting of all the of the nerves located outside the central nervous system. | peripheral nervous system |
| A change or signal in an organism’s surroundings that causes the organism to react. | stimulus |
| A cell that carries information through the nervous system. | neuron |
| The clear tissue that covers the front of the eye | cornea |
| The opening through which light enters the eye. | pupil |
| A sheet of light sensitive cells that lines the back of the eye. | retina |
| The junction where one neuron can transfer an impulse to another structure. | synapse |

| The thick column of nerve tissue that links the brain to most of the nerves in the peripheral nervous system. | spinal cord |
| The part of the brain that interprets input from the senses, controls movement, and carries out complex mental processes. | cerebrum |
| The part of the brain that coordinates muscle action and helps maintain balance. | cerebellum |
| The part of the nervous system that controls most functions in the body. | brain |
| The group of nerves in the peripheral nervous system that controls voluntary actions. | somatic nervous system |
