Abstract

Contractions induced by adenosine triphosphate, in myofibrils isolated from the barnacle, Balanus aquilia, were observed with a phase microscope. The formation of contraction bands was well under way before the A-band came into contact with the Z-membrane. This is in disagreement with the hypothesis that contraction bands are formed when the A-band pushes against the Z-membrane.

摘要

用相差显微镜观察了从藤壶Balanus aquilia分离出的肌原纤维中由三磷酸腺苷诱导的收缩。在A带与Z膜接触之前，收缩带的形成就已经在顺利进行了。这与A带推向Z膜时形成收缩带的假说不一致。
