Spinal Cord Segment Model

Six-times life-size, this vinyl plastic model replicates a segment of the upper thoracic spinal cord. Sectioned both longitudinally and in cross section, a portion of white matter of the right half has been cut away to expose the anterior and posterior nerve roots.

Color-coding differentiates nerve fiber type and a color-keyed circuitry schematic is mounted along with the model on a hardwood base. 30 numbered features are identified in a corresponding key.

Overall dimensions of base: 12x8x5 inches (30x20x13 cm).
