L2
How to tell apart different levels of the spinal cord
- Cervical: large and oval. large amount of white matter (many axons going up to the brain & travelling down from the brain). The ventral horn is enlarged.
- Thoracic: Small and circular.
- Lumbar: Large and circular.
- Sacral. Small and circular.
