2 - Take Your Position - Review
Key points of spinal anatomy:
- Spinal bones are called vertebrae.
- The spine is formed by 24 vertebrae.
- A disc sits between each vertebral set.
- The disc has two parts: the inner nucleus, and the outer annulus.
- A bony ring on the back of each vertebra forms the spinal canal that protects the spinal cord.
- Two facet joints sit between each vertebral set, one on the left and one on the right.
A spinal segment is made up of:
- Two vertebrae, one on top of the other.
- A disc between the two vertebrae.
- Two nerves that leave the spinal cord at each level, one on the left and one on the right.
- The small facet joints that link the two vertebrae together.
The spine has three natural curves.
- The neck and low back curve inward (lordosis).
- The midback curves outward (kyphosis).
- The spinal curves help balance and cushion the spine.
Spine health is maximized by keeping the spine balanced, or centered.
- When the parts of the spine are out of balance, they don't work as well
- Using imbalanced postures upsets lifelong spine health.
- Imbalanced spine postures may not cause pain right away.
- The neutral spine position combats abnormal and excessive strain on the back.
Aerobic exercise is an important part of recovery after
- It is recommended in most guidelines for treating low back pain.
- It can help relieve the stress that often goes along with having back pain.
- It can help keep you fit.
- It can help your body release endorphins, the body's own natural painkiller.
