For a muscle contraction to take place, there must be a stimulation first to form an impulse (action potential) from a neuron that connects to the muscle. Filamentation (or filamentary structure) is often seen in plasmas.It is created because plasma contains free electrons, making it highly electrically conductive — even more than metals, and even in tenuous cosmic plasmas.As charged particles readily move in a plasma, a ring of magnetic field forms around the current that can pinch it into filamentary current strands (ie.
