A main work on muscular action, the "Elements of Myology," by the Danish anatomist Niels Stensen (1638-1686) was written at a time when the teachings of Hippocrates, Erasistratus, Aristotle, & Galen were still the foundations upon which scholarly learning on the human body were built. In this work as in several other areas of research, Stensen described a structure vs. time relation as a dynamic process. From macroscopic observations of a number of muscles in several animal species, he described the contraction of compound muscles arranged in unipennate structures with an angle between muscle fibers & tendons. He found that the observed swelling of a muscle during contraction was not an argument for an expansion of its volume.
