#axolemma

• Axolemma — A specialized plasma membrane (plasmalemma) that completely surrounds and structurally delimits the axon of a nerve cell. This fine cellular barrier plays a crucial physiological role in maintaining the resting potential and in the ultra-fast propagation of the action potential via voltage-gated sodium and potassium channels, ensuring a delicate and coordinated transmission of the nerve impulse toward other synapses.
