**Understanding Action Potential in Neurons**

After an action potential is generated in a neuron, it travels to the end of the axon. Explain how the absolute refractory period prevents the action potential from traveling back to the cell body, and why it does not prevent the action potential from moving down to the end of the axon.

For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

Expert Solution

Step 1

The period from the simulation of an axon triggering generation of action potential till the period when the resting membrane potential is restored after by Sodium Potassium ATPase pump is called refractory period. During this period the second action potential cannot be initiated even with a strong stimulus.
