The spine is a tubular structure made up of nervous tissue that prolongs from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord that contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system. There are 31 segments in a human spine: 8 cervical segments, 12 thoracic, 5 lumbar segments, 5 sacral segments and 1 coccygeal segment as showed in figure 1. Mainly neck pain caused when cervical segments will undergo stress whereas back pain is due to thoracic segments.
