The Spinal cord model illustrates the composition of the spinal cord, magnified to a scale of about 5:1.
The spinal cord is formed by a central channel surrounded by "gray matter" with an outer layer of "white matter". The base of the model features illustrations of the various cross-sections of the spinal cord through the white and gray matter at the neck, torso and lumbar and sacral regions. The Spinal Cord Model with Nerve Endings is supplied on a base. Great for teaching anatomy of the human nervous system.
