Berend E Westerhof
Two cross over cycles and one spinous interaction are back to (behind) the vertebral body. In the middle of each pair of vertebrae are two little openings called intervertebral foramina. The spinal nerves leave the spinal rope through these openings. From behind, the vertebral segment presents in the middle line the spinous cycles. In the cervical area (except for the second and seventh vertebrae), these are short, even, and bifid. In the upper piece of the thoracic locale they are coordinated at a slant descending; in the center they are practically vertical, and in the lower part they are almost level. In the lumbar locale they are almost level.
