Abstract
Each vertebra is composed of a vertebral body, vertebral arch, and bony appendages. The superior and inferior articular processes make up the zygapophyseal (facet) joint. Each vertebra has two sets of facet joints. The pars interarticularis is the narrowed portion of the vertebral arch between the superior and inferior articular processes. The neural foramen is bounded by the pedicles of the corresponding upper and lower vertebral levels. Normally, the intervertebral disk shows central T2 hyperintensity and peripheral T2 hypointensity. The spinal nerve roots are named with respect to the corresponding lower vertebral level from C1 to C7 and to the corresponding upper vertebral level from T1 to S5, due to the C8 nerve root situated between the C7 and T1 vertebrae.
