WebIn the adult nervous system neurofilaments in small unmyelinated axons contain more peripherin and less NfH whereas neurofilaments in large myelinated axons contain more NfH and less peripherin. The type III intermediate filament subunit, vimentin , is expressed in developing neurons and a few very unusual neurons in the adult in association with type … WebConduction delays vary greatly in the mammalian nervous system, from < 100 microseconds in very short axons to > 100 ms in very long non-myelinated central axons. In all but a few cases, axonal conduction delays have been measured using physiological recording methods, which have very high temporal resolution, but usually measure conduction … WebGanglion tissue is composed of cell bodies, dendrites, and satellite glial cells.
