Place each of the following labels in the proper position on the curve when each of the indicated items would occur
A:
1. When sodium ions arrrive at the axon hillock, they depolarize the membrane at that point
2. Potential across the membrane is becoming less negative
B:
1. At threshold, voltage-gated Na+ channels open quickly
2. Threshold
3. -55 mV
4. Sodium inflow is greater than at resting membrane potential or any other time
C:
1. Voltage-gated potassium channels open
D:
1. Hyperpolarization
E:
1. Resting membrane potential
2. -70 mV
