| is the name of the nervous system division that includes the brain and spinal cord. | CNS |
| A group of peripheral axons bundled together in an epineurium is called a? | Nerve |
| The two types of cells found in the nervous system are | Neuron and Glia |
| The knee jerk is a type of neural pathway called a? | Reflex Arc |
| is a self propagating wave of electrical disturbance that travels along the surface of a neuron's plasma membrane. | Nerve Impulse |
| The exterior of the resting neuron has a slight charge, whereas the interior has a slight ___________ charge. | Positive, Negative |
| The is a place where impulses are passed from one neuron to another. | Synapse |
| Acetylcholine and dopamine are examples of _________, which are chemicals used by neurons to communicate. | Neurotransmitters |
| the three membranes that make up the meninges are. | Dura mater, Arachnoid Mater, and Pia Mater |
| Cells that make myelin for axons outside the CNS | Schwann Cells |
