1. the axon

2. the axon During a nerve impulse…….

3. the axon During a nerve impulse……. Na + moves in

4. the axon During a nerve impulse……. Na + moves in K+ moves out

5. the axon At rest……. more negative

6. the axon At rest……. more negative less negative

7. the axon During a nerve impulse……. positive negative … for a brief period of time only!

8. the axon During the resting state……. Lots of Na + out here

9. the axon During the resting state……. Lots of Na + out here but not much K +

10. the axon During the resting state……. Lots of Na + out here but not much K + Lots of K+ in here but not much Na+

11. the axon During the resting state……. Lots of Na + out here but not much K + Lots of K+ in here but not much Na+ Lots of Cl - out here

12. the axon During the resting state……. Lots of Na + out here but not much K + Lots of K+ in here but not much Na+ Lots of Cl - out here Not much Cl - in here

13. the axon During the resting state……. Lots of Na + out here but not much K + Lots of K+ in here but not much Na+ Lots of Cl - out here Not much Cl - in here Lots of negative organic ions here

14. the axon During the resting state……. Lots of Na + out here but not much K + Lots of K+ in here but not much Na+ Lots of Cl - out here Not much Cl - in here Lots of negative organic ions here NO negative organic ions here!
