Abstract

The activities of sodium, potassium, and hydrogen in the myoplasm of single muscle fibers from the giant barnacle were measured by cation-sensitive microelectrodes as the temperature of the bathing solution was increased from 7 to 40 °C. An irreversible shortening occurred in all fibers between 37 and 40 °C. When the fibers shortened in a sodium-free Ringer solution, the mean activity of sodium increased by 130%, the mean activity of potassium remained relatively constant, and the pH decreased from 7.17 to 6.77. The results have been interpreted as meaning that at 37–40 °C there was a disruption of the myofilaments and a release of associated sodium ions.
