Axolemma

Called the axolemma or axolemma ( AltGr. Ἄξων axon ' axis ' and εἴλημα Eilema ' cloth '), rare Mauthnersche vagina, is the continuation of the cell membrane, plasmalemma, in the area of the axon, a projection of nerve cells.

The axolemma, surrounding the axoplasm biomembrane is basically similar in structure to the rest of the cell membrane of a nerve cell. Specific membrane regions along the axon can be found usually in the initial section as the Initialsegement where action potentials are initiated, and in the end than the Axonterminale, where mostly a presynaptic formed for example as endpin.

In the middle course of the nerve cell membrane route shows in axons, which carry a myelin sheath, an alternating alternating between internode to Node of Ranvier structure due to the specific nature of the forwarding of action potentials. Such a nodal axolemma is distinguished in the field of Ranvier node that is characterized by its dense stocking with sodium channels (which are necessary for saltatory conduction here). In internodal axolemma these channels come before then only sparsely.
