What happens to an action potential as it travels along an axon?

It increases in strength.

It decreases in strength.

It increases in speed.

It remains constant

Solution

Action potential is the change in electrical potential associate with the passage of an impulse along the membrane of a muscle cell or nerve cell.

When the action potential travels along an axon its strength remains constant i.e it does not change. Also, the speed remains constant. So, the correct answer is option D (It remains constant).
