All of the realism of an actual skeleton has been captured by the process used to mold this durable and functional teaching aid. An ideal skeleton was selected and used in preparing the production mold for the skeleton materials and the bones, carefully cast to preserve even the finest details. The characteristics of natural bone have been so faithfully duplicated that it would take chemical analysis to distinguish these materials from natural bone. Each bone is cast individually in natural color with all details of anatomy represented. Wherever possible, there is natural movement in the joints. This reproduction is made of special plastic which does not deteriorate with age and which is unbreakable. It can be easily washed with soap and water for years of continuous use. The skeleton is mounted in an upright position on a nonrusting mobile stand. The fully articulated legs and arms on this advanced skeleton are removable, as well as the skull with 32 teeth. The mandible is hinged with springs, and the calvarium is sectioned to permit study of the cranial vault. This functional, durable skeleton features detailed paintings of muscle origins in red and muscle insertions painted in blue. All muscle numbers are easily identified. The muscles are accurately painted at the correct positions under the supervision of anatomists. Bones and muscles are numbered for identification. Includes a comprehensive key. 5 ft. 6" tall.
