The spine has 5 lumbar vertebrae(L1-L5) supporting the body weight. While classified as peripheral nerves, the motor cell body resides in the anterior horn of the spinal cord. The principal movements permitted by the vertebral column are: flexion (bending forward), extension (bending backwards), lateral flexion (bending right/left), and rotation (torsion/twisting). As with other spinal vertebrae, the T8 primarily protects and encases the spinal cord. It also supplies blood to two very important regions of the brain: the posterior fossa and the occipital lobes.
