Teased myelinated axon
WebbAbstract. The membrane of the myelinated axon expresses a rich repertoire of physiologically active molecules: (1) Voltage-sensitive NA+ channels are clustered at high density (approximately 1,000/microns 2) in the nodal axon membrane and are present at lower density (< 25/microns 2) in the internodal axon membrane under the myelin. WebbNervous tissue with few myelinated axons appears gray, the color of ner vous tissue cells. Groups of myelinated axons in the CNS form tracts and are called white matter, whereas unmy clinated areas comprised of neuron cell bodies, dendrites, axon terminals, and neuroglia are called gray matter.
