In the chapter concerning the skeleton, the user can show chromatically the various details of a particular bone. This can also be done on radiographic images (RX). The zoom function allows enlargement of the bone in order to better show its morphology and measure the dimensions. Thanks to the technology of QuickTime VR, virtual rotation of the bone is possible, in order to see it from different angles. In addition, a synthesis is provided, where students can acquire the essential terminology of a determined anatomical part. In the chapter on joints, the user can show the individual characteristics of each joint, ligament, the morphology of joint surfaces, joint discs and meniscus. In addition, the films with commentary, made with 3D animation, show their possible movements. In the chapter dealing with muscles, the user has the possibility to isolate each single muscle, showing the points of origin and termination. In parallel, in the section on Magnetic Resonance (RM) and Computed tomography (CT), the muscles are shown chromatically in the transverse, frontal and sagittal planes.
