The Membrane Components of Crustacean Neuromuscular Systems.

Abstract

The present work provides additional evidence for the occurrence of a number of electrogenic components in crustacean and particularly crayfish muscle fibers. It demonstrates that these different components are independent. One or another can be eliminated or modified by various procedures without affecting the rest. However, interactions can occur between the different components. The coupling may be effected by the changes in membrane potential which result from changes in ionic permeabilities or by changes in the membrane conductance. Some interactions of such couplings which can perturb electrophysiological measurements are described and analyzed.
