Legs and arms are removable as well as the skull. Mandible hinged with springs, calvarium sectioned to permit study of the cranial vault. The skull has a full set of teeth. 5 ft. 7" tall. 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. Skeleton is mounted in an upright position on a nonrusting mobile stand.
