Cervical disc herniation
General information
Important applied anatomy in a herniated cervical disc:
1. in the cervical region, the cervical nerve root exits above the pedicle of its like-numbered vertebra (opposite to the situation in the lumbar spine, due to the fact that there are 8 cervical nerve roots and only 7 cervical vertebrae)
2. as each nerve root exits through its neural foramen, it passes in close relation to the undersurface of the like-numbered cervical pedicle
3. the intervertebral disc space is located close to the inferior portion of the cervical pedicle (unlike the lumbar region).
