nerve fibers that are short, highly branched, and neuron's main receptive surfaces; extend out of the cell body
single nerve fiber that transmits impulse away from the axonal hillock of the cell body
found throughout cytoplasm and contains ribosomes-> protein synthesis
tubular, cytoplasm filled fibers that conduct impulses to or from the cell body
neurological cell that is wound tightly around the axon and secretes myelin
layers of lipo-protein surrounding axons; sheath-like; layers secreted by Schwann cells
sheath located outside myelin made of cytoplasm and nuclei of Schwann cells
nodes of ranvier
narrow gaps in myelin sheath between Schwann cells
