Human Spinal Cord

The upper thoracic spil cord is rendered in longitudil and cross section, and enlarged 6, to show dorsal and ventral nerve roots with ganglia, as well as the blood supply. Each type of nerve has been painted a different color: afferent visceral nerves - green; afferent somatic nerves - yellow; efferent visceral nerves - red; and efferent somatic nerves - black. The model is mounted on a base, which features a circuitry diagram with numbered Key Card.
