Figure 1
Tension record of a muscle bundle through the recording of the X-­ray diffraction patterns shown in Fig. 2[link]. Application of acetylcholine (Ach) and 5-hydroxytryptamine (5HT), as well as washing (W) them, are shown by the short arrows. The X-ray diffraction patterns in the contracting (C) and resting (R) states were taken at the positions shown by the long arrows. The pattern in the contracting state was taken after three stimuli when the tension reached a maximum (Twarog, 1967BB20). The muscle bundle was set at the centre of the incident X-ray beam during the first two stimulations and the following slow relaxations (Tajima et al., 1994BB19). The muscle bundle generated a tension of 12.2 kg cm−2 during X-ray exposure in the contracting state. In the interval marked with the star, the chart speed was slowed down by a factor of 1/60.
