We call it our super-skeleton, because it combines all features in just one skeleton: It is flexible in the spinal region and with nerve-ends (like our A 200.2), it has the muscles painted on one side of skeleton (like our A200.1), it has ligaments of shoulder, elbow, hip and knee and in addition it has over 300 numbers which describe bones, bony parts, sutures, fissures, foramina etc.
