Subcellular electrical characteristics of amphibian muscle: II. Colloidal changes in polarized gastrocnemius muscle



Subcellular electrical characteristics of amphibian muscle: II. Colloidal changes in polarized gastrocnemius muscle



J Amin Morphol Physiol 11(2): 280-284



Gastrocnemius muscles of Rana hexadactyla were exposed to direct current electric field. The cathode 1/2 was swollen and became slightly transparent, while the anode 1/2 was shrunk and became slightly opaque. Fixed and isolated individual muscle fibers have a larger width in the cathode 1/2 and a lesser width in the anode 1/2 than in the controls. The water content was less in the anode 1/2 and remained unchanged in the cathode 1/2. The subcellular protein fraction may migrate to the cathode 1/2 increasing the total water content, and the loss of water may be due to electrolysis compensating for this increase. The increase in width of the muscle fiber in the cathode is due to the accumulation of substances from the anode.
