Multiple Choice

For the following questions, refer to the graph of an action potential.

• A) no action potential will be initiated.
• B) an action potential will be initiated and proceed only in the normal direction toward the axon terminal.
• C) an action potential will be initiated and proceed only back toward the axon hillock.
• D) two action potentials will be initiated, one going toward the axon terminal and one going back toward the hillock.
• E) an action potential will be initiated, but it will die out before it reaches the axon terminal.
