Low voltage electricity causes changes which may be divided into two groups: 1. Actin and myosin damage in the primary and secondary fibers, predominantly in the A-segments. 2. Changes due to hypercontractional relaxation of the fiber. These may include tearing of the fibers. In this group destruction of the mitochondria corresponds to morphologic changes in density. Electronmicroscopic histochemical methods enable characteristic localization of activity alterations. In the first group there are no changes visible by light microscopy but they are clearly evident in the second group. The changes suggest a relationship to the flow of current.
