This full-size human skeleton is a wonderful addition to any classroom or medical office. Skeleton is cast with naturally colored plastic, and the left side is painted and labeled to realistically display the muscle origins in red and muscle insertions in blue. Spinal column is color-coded and labeled. All vertebral arteries, spinal nerves and intervertebral discs are shown, including a prolapsed L3-L4 intervertebral disc. The three-part skull features a removable skullcap and mandible, suture lines and a full dentition. Skeleton has been wired for natural movement and the arms and legs are detachable for closer examination. Comes pelvic mounted on a roller base and includes an easy-to-read corresponding colored diagram.
