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. This durable skeleton features joint ligaments, a flexible spine with nerve endings, and full indication of muscle origins (in blue) and insertions (in red) painted on the right side of the body. Skull is dissectible into three pieces, with removable calvaria and lower jaw. Axial skeleton is mounted to allow natural movement of the skull on the 1st and 2nd cervical vertebrae. Flexible spine includes all spinal nerves and the vertebral artery. The skull, left arm, and left leg are detachable. The iliocostal and longissimus muscles are painted differently for clearer understanding. The right side has ligaments of the shoulder, elbow, hip, and knee reproduced. The left side of the skeleton is provided with numerical notation of the major bones, bone parts, fissures, and foramen. 5 ft. 6" tall.
