发帖数: 616 | 1 The following table shows muscle length and muscle tension.
At which muscle length is the max muscle extension is achieved?
length (cm), Passive tension(g), Total tension(g)
10 0 0
15 10 12
20 20 24
25 30 40
30 40 42 |

发帖数: 616 | 3 恩，请给解释解释吧。尤其是 passive and total tension的概念。 |

发帖数: 356 | 4 active force=total force - passive force. 40-30=10是里边的最大值。意外着这时
muscle length是optimal length. 超过这个length了，active force下降了。 |

发帖数: 616 | 6 我也想过不会是减法那么简单吧 。。。
另外如何判断是optimal length？就是因为40-30=10是里边的最大值？ |

发帖数: 356 | 7 total force就是２部分相加：active和passive。所以40-30就是active force的值。
判断optimal length 就是产生最大active Force的时候。这是因为这时actin和myosin
overlap在最佳长度，产生的crossbridge最多。 |
