The Spinal Cord extends from the skull to your lower back and travels through the middle part of each stacked vertebra, called the Central Canal.
Nerves branch out from the spinal cord through openings in the Vertebrae and carry messages between the brain and muscles.
The Spinal Cord ends around the first and second Lumbar Vertebrae in the lower back and continues as nerve roots. This bundle of nerve roots is called the CAUDA EQUINA. They exit the spinal canal through openings in the Vertebrae (Foramen), just like other nerve roots. In the Pelvis, some of the nerves group into the Sciatic Nerve, which extends down the leg.
