LEARN MORE ABOUT SPINAL NERVES – Snells clinical anatomy illusrated with Q&A Book PDF Download
- • Spinal nerves are made up of a ventral (motor) root and a dorsal (sensory) root. There are 31 pairs (L & R).
- • Cell bodies for sensory nerves are in dorsal root ganglia. Motor nerve cell bodies are in ventral horn of spinal cord.
- • Roots exit spinal column via the intervertebral (neural) foramen (under pedicle); (C1-7 exit above their vertebrae,
C8-L5 exit below their vertebrae [C7 exits above and C8 exits below C7 vertebra]).
• They can be compressed by herniated discs, osteophytes, and hypertrophied soft tissues (ligamentum fl avum,
facet capsule). In lumbar spine the traversing nerve is usually affected, and exiting root is not (except in far lateral
• The lumbar and sacral nerves form the cauda equina (“horse’s tail”) in the spinal canal before exiting.
• Spinal nerve divides into dorsal and ventral rami. Dorsal rami innervate local structures (neck and back musculature,
overlying skin, facet capsules, etc). Ventral rami contribute to plexus (e.g., cervical, brachial, lumbosacral) and become
peripheral nerves to the extremities.
• Ventral rami of spinal nerve commonly referred to as a spinal “roots.” The roots combine to form the various plexus.
