axoplasmic flow

[ak′sōplaz′mik]
Etymology: Gk, axon + plassein, to shape
the continuous pulsing, undulating movement of the cytoplasm between the cell body of a neuron, where protein synthesis occurs, and the axon fiber to supply it with the substances vital for the maintenance of activity and for repair. The nerve fiber depends totally on the cell body for metabolites, and any interruption in the axoplasmic flow caused by disease or trauma results in the degeneration of the unsupplied areas of the axon.

axoplasmic

pertaining to or emanating from axoplasm.

axoplasmic flow
the flow of proteins, hormones, enzymes and neurotransmitters along nerve fibers.
