Across
- 4. disorder characterized by the widespread degeneration of myelin
- 6. increase in membrane potential
Down
- 1. temporarily unresponsive or inactivated
- 2. stimulus intensity that is just adequate to trigger an action potential
- 3. a decrease in membrane potential
- 5. small changes in membrane potential
- 7. gap between successive segments of the myelin sheath where the axon membrane is exposed
