The spinal column is, as the name suggests, a column that runs along the length of the spine. It is composed of four primary sections – cervical (neck), thoracic (middle back), lumbar (lower back), and sacral (pelvis). When viewed from a posterior aspect, the spinal column appears to run in a straight line down the back. When viewed laterally, it becomes evident that the column actually curves in a convex and concave S-shaped pattern from the base of the skull to the pelvis. The role of the spinal column is to provide skeletal support and flexibility for the upper body and to protect the delicate components of the spinal cord and associated nerve roots.
Anatomical Components of the Spinal Column
The anatomy of the spinal column is a complex amalgam of bone, soft tissue, and membrane. The different parts include:
Degenerative Conditions That Affect the Spinal Column
All of these anatomical components are subject to deterioration associated with the aging process. These include degenerative disc disease, spinal stenosis, osteoarthritis, and more. For information on how to combat these age-related degenerative spine conditions, contact Laser Spine Institute.
