Across
- 2. need a charge or certain voltage to open
- 5. place where threshold is reached
- 6. Temporary change in charge
- 10. need a physical distortion to open or close
- 11. axons used for continuous propagation
- 13. channels that allow ions to leak
- 15. number of potassium ions that come in through the Na+/K+ pump
- 16. Follow the all or none principle
Down
- 1. axons used for saltatory propagation
- 3. does not lead to an action potential
- 4. Cytosol is full of this positively charged ion
- 7. need a chemical to open
- 8. become more positive from rest
- 9. one of the places where graded potentials occur most often
- 12. enzyme used by the Na+/K+ pump
- 14. Form in which P- would be removed from the cell
