Tension transients in single isolated smooth muscle cells.
Tension transients have been recorded for the first time in a single smooth muscle cell. The transient contains a linear elastic response and a biphasic recovery which appear to originate from the cross-bridges. A comparison of transients in smooth and fast skeletal muscle fibers suggests that the cross-bridge in smooth muscle is more compliant than in striated muscle and that transitions between several cross-bridge states occur more slowly.
