A COMPARISON OF THE TIME RELATIONS OF MUSCLES SUPPLIED BY NORMAL AND BY REGENERATED NERVES

Abstract

In more than 1000 tests on 20 white rats muscles supplied by regenerated nerves whose constituent axons were markedly smaller than those of the control nerves were shown to have the same chronaxie as the control muscles, and the same duration of isotonic and isometric twitches as the controls, and to develop the same tension, indicating that there is no causal relation between the time characteristics of a muscle and the diameter of the motor axons supplying it.
