The spine is one of your most important body parts. Without a well-functioning set of vertebrae, you couldn’t do much of anything, and the rest of your body might quit their jobs as well.
Your spine needs to be in good structural condition. Every bone needs to stay undamaged; every piece of cartilage should remain smooth, each muscle and tendon relaxed and functional.
If you want to keep your back in its best shape, it will help to know its parts, what they do, and how to keep your spine stable and fit.

The Segments of the Spine
The cervical spine is the first segment of seven vertebrae at the top. It holds your head and neck.
The thoracic spine is the second segment, located in the middle portion of your body. It consists of 12 vertebrae that control the mid-back region.
