Axoplasm

Axoplasm is the cytoplasm within the axon of a neuron (nerve cell). Neural processes (axons and dendrites) contain about 99.6% of the cell’s cytoplasm, and 99.7% of that is in the axons.

Axoplasm has a different composition of organelles and other materials than that found in the neuron's cell body (soma) or dendrites. In axoplasmic transport, materials are carried through the axoplasm to or from the soma.
