The vertebral segment is a mechanical wonder in that it must bear the cost of both unbending nature and adaptability. The Spine as a whole the segmental plan of the vertebral segment permits satisfactory movement among the head, trunk, and pelvis; bears assurance of the spinal string; moves weight powers and bowing snapshots of the chest area to the pelvis; offers a shock absorbing device; and fills in as a turn for the head. Without adjustment from the spine, the head and upper appendages couldn't move uniformly, easily, or bolster the heaps forced upon them. Basically on account of its different grown-up bends, the hard spine is anatomically partitioned into the seven cervical vertebrae, the twelve thoracic vertebrae, the five lumbar vertebrae, and the solidified five sacral and four coccygeal sections. From C1 to S1, the articulating portions of these vertebrae are the vertebral bodies, which are isolated by intervertebral circles (IVD's), and the back aspect joints. The IVD's will in general be static weight-bearing joints, while the aspects work as unique sliding and floating joints. The adaptable vertebral segment is adjusted upon its base, the sacrum. In the erect position, weight is moved over the sacroiliac joints to the ilia, at that point to the hips, and afterward to the lower limits.
