Axoplasm is the
cytoplasmwithin the axonof a neuron. Neural processes (axons and dendrites) contain about 99.6% of the cell’s cytoplasm, and 99.7% of that is in the axons (Sabry et al., 1995).
Axoplasm has a different composition of
organelles and other materials than that found in the neuron's cell body or dendrites. In axoplasmic transport, materials are carried through the axoplasm to or from the soma.
electrical resistanceof the axoplasm, called axoplasmic resistance, is one aspect of a neuron's cable properties, because it affects the rate of travel of an action potentialdown an axon. If the axoplasm contains many molecules that are not electrically conductive, it will slow the travel of the potential because it will cause more ions to flow across the axolemma(the axon's membrane) than through the axoplasm.
