Question
The normal site for action potential generation for most neurons is the Blank______.
Multiple choice question:
- trigger zone
- node of Ranvier
- axon terminal
Solution
The correct answer is the trigger zone.
Explanation:
-
Trigger Zone: This is typically located at the axon hillock of neurons, where the action potential is generated. It is the area where the sum of inputs from dendrites and the cell body reaches the threshold to initiate an action potential.
-
Node of Ranvier: These are gaps in the myelin sheath along the axon, and while they play an important role in the propagation of action potentials via saltatory conduction, they are not the primary locations for generation.
-
Axon Terminal: This part of the neuron is responsible for transmitting signals to other neurons or muscles, but it does not generate action potentials.
In summary, the trigger zone is the site where action potentials are typically generated in most neurons.
