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

The correct answer is (D) Both A and B

Explanation:

When an axon is depolarized at halfway to the threshold level,the action potential will be generated that would travel 'downstream' i.e towards the synapse and 'upstream' i.e back towards the cell body. This is because both channels on either sides are not under refractory period,i.e they are open.

Both A and B

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

Explanation:

An action potential can be define as a process that occurs when axon receives the information sent down by neuron from the cell body.

An action potential make it possible for neuron to help transport electrical signal and this happens when the neurons generate and conduct these signals along their processes in order to transport them to the target tissues or to the next neuron and this action potential will as well be generated in order to travel back towards the cell body.

The action potential often begins in the nerve fibre because it enables graded potential to reach the threshold potential which in turn causes an ACTION POTENTIAL.

Therefore in action potential the membrane potential of the location of the cell often rise and fall.

Axon or nerve fibre also helps to transport information to various neuron.

answer; the above is a (true) statement;

hope this !
