Anatomy of the Spine
What are the sections of the spine?
The spine is made up of vertebrae and is divided into three main sections:
- Cervical (7 vertebrae)
- Thoracic (12 vertebrae)
- Lumbar (5 vertebrae)
Below the lumbar spine is the sacrum which is comprised of five fused vertebrae. At the end of the spine is the coccyx, or the tailbone.
The vertebrae bear the weight of the upper body and provide points of attachment for muscles and ligaments. It also protects the spinal canal and provides exit points for spinal nerves.
The individual vertebrae are separated by intervertebral discs, which act as cushions or shock absorbers between the vertebral bodies.
Is my spine causing my neck and arm or low back and leg pain?
Age, genetics, injury, and everyday wear and tear caused by routine activities can contribute to damage and deterioration of the disc(s) in your neck and back.
