In many elementary and advanced texts of physiology and anatomy, the section on skeletal musculature is crowned by a series of drawings which show the human skeleton as a complex mechanism replete with hinges, pulleys, beams, trusses, etc. The muscles appear as winches, engines, cables or springs, and the main point seems to be an analysis of the complexity of human movement into a form of energy release which is ultimately shortenings and lengthenings. This approach has its value, but directs one’s attention to movement as a whole phenomenon by presenting muscle itself in a mechanical, oversimplified fashion. It is clearly asking too much that every individual’s knowledge of the human body should include all the latest facts in every area. But it is desirable, even necessary, I believe, that the overall maps or models by means of which one integrates his store of information at least have room for such facts as he may discover. The chief deficiency of a model of the human body which presents muscle as cables or springs, is the oversimplification of what muscle metabolism is and how it relates to the rest of the body’s activity. Dr. V. Reggie Edgerton is a young scientist engaged in histochemical research into muscle tissue at U.C.L.A. In the following interview he gives us an idea of the complexity of this field.
