Contractile Properties of Esophageal Striated Muscle: Comparison with Cardiac and Skeletal Muscles in Rats
Figure 1
Single-pulse electrical stimulation-induced twitch-like contractions of esophageal, skeletal, and cardiac muscles in rats. (a) Representative traces of the contractile responses to electrical field stimulations (EFS) in esophageal, skeletal, and cardiac muscle preparations are shown. EFS was applied by using single pulses (voltage: 80 V, duration: 10 ms). Closed circles indicate the points of EFS. (b) Summary graphs of the duration of the EFS-evoked twitch-like contractions in esophageal skeletal , and cardiac muscle preparations. Each bar represents the mean ± S.D. shows significant difference (). NS shows no significant difference.
