| related to saltatory conduction | nodes of Ranvier |
| thick, tough, superficial meninge | dura mater |
| branch of nervous system that controls involuntary muscle and glands | autonomic |
| what direction do impulses travel at a synapse | from axon to dendrite of next neuron |
| when does inward movement of sodium ions into a neuron occur | depolarization |
| structure that connects right and left cerebral hemispheres | corpus callosum |

| classification of spinal nerves | mixed |
| inability of a neuron to accept a stimulus while the neuron is still depolarized | refractory period |
| spinal nerves that emerge from inferior end of spinal cord | cauda equina |
| function of gray matter of spinal cord | reflex center |
