{{short description|Cytoplasm found within the axon of a neuron}} {{Infobox anatomy | Name = Axoplasm | Latin = axoplasma | Image = | Caption = | Image2 = | Caption2 = | Precursor = | System = [[Nervous system]] | PartOf = [[Axon]] of a [[nerve]] }} '''Axoplasm''' is the [[cytoplasm]] within the [[axon]] of a [[neuron]] (nerve cell). For some neuronal types this can be more than 99% of the total cytoplasm.<ref>{{cite journal |last1=Sabry |first1=J. |last2=OโConnor |first2=T. P. |last3=Kirschner |first3=M. W. |year=1995 |title=Axonal Transport of Tubulin in Ti1 Pioneer Neurons in Situ |journal=Neuron |volume=14 |issue=6 |pages=1247โ1256 |doi=10.1016/0896-6273(95)90271-6 |pmid=7541635 |doi-access=free }}</ref> Axoplasm has a different composition of [[organelle]]s and other materials than that found in the neuron's [[cell (biology)|cell]] body ([[soma (cell body)|soma]]) or dendrites. In [[axonal transport]] (also known as axoplasmic transport) materials are carried through the axoplasm to or from the soma. The [[electrical resistance]] of the axoplasm, called axoplasmic resistance, is one aspect of a neuron's cable properties, because it affects the rate of travel of an [[action potential]] down an axon. If the axoplasm contains many [[molecule]]s that are not [[electrical conduction|electrically conductive]], it will slow the travel of the potential because it will cause more [[ion]]s to flow across the [[axolemma]] (the axon's membrane) than through the axoplasm.
