This life-sized human skeleton model features unbreakable plastic bones which were carefully cast to preserve the finest details. The mandible is hinged; the arms, legs and skull are removable; and the calvarium is sectioned to allow for study of the cranial vault. There is natural movement in the joints wherever possible. The jaw features a full set of teeth, three of which are removable for closer examination. The spinal column shows the spinal cord, nerve exits, vertebral arteries, and a herniated disk. The skeleton is mounted in an upright position on a heavy duty base with smooth gliding casters. A dust cover and detailed key are included. Life-Sized : 5ft, 7in.
