Abstract
Carbachol in a concentration of 5x10(-8) mol/liter does not hyperpolarize, and in a concentration of 5x10(-6) mol/liter depolarizes the membrane of somatic muscle cell in earthworm. d-tubocurarine, alpha-bungarotoxin, atropine, and hexamethonium added to the incubation medium did not abolish the carbachol-induced decrease in resting membrane potential. Each of these drugs alone had no effect on resting membrane potential in muscle cells. Presumably, the acetylcholine-sensitive receptor-channel membrane complex in earthworm muscle cell differs from acetylcholine receptor in skeletal muscle fibers and peripheral neurons of vertebrates.
