With Central Nervous System Detail
Replicate the normal twisting and bending movements of the spine with this Advanced Flexible Skeleton model. A flexibly articulated spinal column permits natural twisting and bending motions of the spine and thorax. You can also illuminate the intimate relationship of the central nervous system to the axial skeleton with the featured paired spinal nerve roots and cervical vertebral arteries shown. Skeleton also includes a herniated lumbar disc between L4 and L5, a detachable sacral flap to expose the branching of the cauda equina, and a resilient spinal cord with medulla.
