- a a chemical released at the distal end of an axon that stimulates an adjacent cell; found in the synaptic vesicles of the axon terminal; initiates electrical current from one neuron to the next by diffusing across the synaptic cleft
- b How does the membrane maintain the difference in electrical charge established by diffusion of ions?
- c nerves carrying both sensory and motor fibers
- d receptive region of a neuron
- e The interior surface fo the membrane becomes less negative and the exterior surface becomes less positive
5 Multiple choice questions

- What is the relationship between myelination and size and conduction velocity?
- the brain and spinal cord collectively
- The amt of stimulus needed to create an action potential. NA+ rushes into the cell increasing the number of positive ions inside the cell and changing the membrane polarity
