The Neuromuscular Junction

  • Robert Plonsey

It is a nerve bundle or nerve trunk that conveys excitatory impulses from the central nervous system to a target muscle. Each nerve fiber is normally myelinated, but at its terminal end it becomes unmyelinated. Also at the end the nerve fiber branches and each branch contacts a single (specific) muscle fiber within the whole muscle.
