Abstract

The external and internal interosseous intercostal muscles were separately stimulated at end-expiratory lung volume in anesthetized dogs. These muscles were all found to elevate the ribs into which they insert. By attaching weights to the ribs, it was determined that the nonlinear compliance of the ribs was responsible for this phenomenon.

摘要

在麻醉犬的呼气末肺容积时，分别刺激肋间外肌和肋间内肌。发现这些肌肉均能提升其附着的肋骨。通过在肋骨上附加重物，确定肋骨的非线性顺应性是造成这一现象的原因。
