Description

This enlarged spinal cord model (6 times life-size) represents the upper thoracic region in both longitudinal and cross-sectional views. It highlights the dorsal and ventral nerve roots with ganglia, along with the blood supply. The model uses color-coded nerves to distinguish between types: green for afferent visceral, yellow for afferent somatic, red for efferent visceral, and black for efferent somatic nerves. Mounted on a base with a labeled circuitry diagram, it is accompanied by a numbered key card for detailed anatomical study.
