Berend E Westerhof*
The vertebral segment, otherwise called the spine is essential for the hub skeleton. The vertebral section is the characterizing normal for a vertebrate in which the notochord (an adaptable pole of uniform arrangement) found in all chordates has been supplanted by a divided series of bone: vertebrae isolated by intervertebral circles. The vertebral segment houses the spinal waterway, a hole that encases and ensures the spinal rope.
