Does the amplitude of the action potential in each fiber in the ulnar nerve increase or do the numbers of nerve fibers in the nerve that respond increase with increased stimulus strength?

Solution

Neuron is the structural and functional unit of the nervous system of our body which forms nerve fibres. Once we are born , the number of neurons in our body cannot increase as they are incapable of cell division , they would rather decrease with ageing.

SO whenever an action potential causes the excitation of nerve that generates a response, it is the strength of stimulus that determines the height of response and not the nerve fibres as they cannot increase
