2. place where information is transmitted form neuron to another
3. level of depolarization a neuron has to reach in order for action potential to occur
7. condition that can affect the brain and spinal cord
8. reflex where a electron is transferred from a sensory neuron to a motor neuron
10. impulse conduction is slower and axon membrane is exposed
11. small temporary change in the electrical potential of a cell
14. principle that states that the response strength of a cell depends on strength of the stimulus
18. action potentials that send information from one neuron to another
19. when cell membranes are excited _____ gates close and Na+ gates open
20. they travel very fast along neurons

1. During this period sodium-potassium pump is actively pumping out 3 Na+ per every 2 K+
4. causes the inside of the cell to be more negative compared to the outside
5. imbalance of electrical charges between neurons
6. causes the inside of the cell to be more positive compared to the outside
9. autoimmune disease where the a immune system attacks _____
12. as this degrades signal conduction decreases
13. nerve cell that conducts electrical pulses away from the cell
15. when action potential is at its highest ____ gates close and K+ gates open
16. this causes waves of depolarisation, repolarisation and refractory periods
17. fundamental part of the nervous system
