Question

Action potentials are normally generated at the axon hillock and propagated down the axon away from the cell body.

If you experimentally depolarized an axon at rest to the threshold level at a point halfway down the axon, what would happen?

A) An action potential would be generated that would travel to the synapse with the next neuron.
B) An action potential would be generated that would travel back towards the cell body.
C) No action potential could be generated at this location.
D) Both A and B.

Answer 1

The correct answers is C

Step-by-step explanation:

The neurons have different parts, one of them is called the body or soma, which is where the action potentials are emitted, because that is where the cell has ion channels to change the internal polarity of the cell by means of an ion exchange with the medium. Axon change is in charge of transmitting the nervous stimulus, NOT CREATING IT, that is why, no matter how much we stimulate it in the axonal zone, the ion channels do not depolarize inside the cell because these channels do not exist in the axon. In addition, other important functions of the axon are to drive axon metabolites and the nutrients that the neuron needs through retrograde and anterograde mechanisms.
