In many presentations of anatomy, the myological, neurological, and angiological body systems are shown isolated, either diagrammatically or schematically. Sometimes these body systems are shown hovering around the skeleton, making it challenging to understand exactly where they lie in the whole body. This publication is designed to allow users to learn anatomy while mapping these systems three dimensionally within the appropriate body context. Building each subsystem -- layer by layer from the inside out -- helps the learner discover anatomical relationships.
