The surface of the nerve axon is formed by the lipid bilayer membrane that is embedded with various proteins including ion ... WebThe nerve fibres are not fatigued even when they are stimulated continuously. All or None Response: A nerve fibre translates either all of the impulse or none at all. If a stimulus is applied upto a threshold level, an action potential will be generated but increasing the strength of the stimulus will not affect the action potential.
