Abstract
- A study has been made of the mechanical behaviour of isolated strips of cat and sheep oesophageal muscle. 2. At 37 degrees C, time to peak tension in an isometric twitch was about 80 ms in both muscles. Tetanic fusion frequency was 30 s-minus 1, twitch: tetanus ratio 0.4-0.47, and maximum velocity of shortening was 3 lengths. s-minus1. 3. The results are compared with the prperties of other muscles.
摘要
- 对猫和绵羊食管肌肉的离体肌条的力学行为进行了一项研究。2. 在37摄氏度时，等长收缩中达到峰值张力的时间在两种肌肉中均约为80毫秒。强直融合频率为30次·分钟⁻¹，单收缩：强直收缩比率为0.4 - 0.47，最大缩短速度为3个肌节长度·秒⁻¹。3. 将结果与其他肌肉的特性进行了比较。
