The length-tension relationship of a preparation of the dorsal body wall of the leech Haemopis sanguisuga was determined. Passive tension is low except at very long lengths of the preparation, when it rises steeply. It is due mainly to the epidermis present in the preparation. The active tension curve is very flat, with tension being reduced only at very short and very long lengths. This shape is explained in the context of the myofilament arrangement of the muscle fibres. It may be that thin filaments can form cross-bridges with different thick filaments at different lengths of the preparation.
测定了吸血水蛭血红蛭背体壁制剂的长度-张力关系。除制剂长度很长时被动张力急剧上升外，被动张力较低。这主要归因于制剂中存在的表皮。主动张力曲线非常平缓，仅在极短和极长的长度时张力才会降低。这种形状可根据肌纤维的肌丝排列来解释。可能是细肌丝在制剂的不同长度时能与不同的粗肌丝形成横桥。
