Tetraethylammonium, Guanidine and Veratrine, applied on the skelettal muscle, caused elevatation of irritability of terminal fibers of motoneuron in that muscle. As its result in the terminal fibers, repetitive excitations were evoked by a single stimulus.
When a single stimulus was applied to a muscle directly, the muscle showed the repetitive excitation, because the action current of a muscle stimulated the terminal fiber antidromically as a ephapse, and then spontaneous excitation occured in the terminal fiber. propagated to the muscle fibers again, and evoked the repetitive contracticns.
Frcm above mentioned facts, it should be concluded that the terminal fiber of motoneuron has a different physiological characteristics from an axon.
