This atlas, in full-color-presents the first published of the five atlas series, real, three-dimensional forms seen from multiple views. The muscles are simply formed, in clay, onto an Equiken™ Professional. The Myologik™ atlas is organized into subsystems, and each volume of the atlas presents one subsystem. This Myologik™ 3 atlas is devoted to the Intrinsic Pectoral subsystem. By building the muscles individually on both the left and right sides of Equiken™, and then turning the model about in space, we present each muscle in the simplest, most direct and informational manner.
