Overview of Spinal Column
The spinal column forms the central axis of the skeleton, supporting the weight of the head, trunk and upper limbs.
Connected to the lower limbs by the pelvic girdle it serves as a support for upright stance and weight bearing. It also permits the transfer of weight and energy to allow locomotion.
Its structure serves to support the strong paraspinal musculature in addition to housing and protecting the spinal column from injury.
The gentle sinuous curvature of the spine, along with the shock absorbing effects of the intervertebral discs, give the spinal column the ability to alter its shape and withstand axial loading quite effectively.
