How many vertebrae are there in each section of the spine?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

What are the 4 spinal areas?

Which part of the spine is most vulnerable to injury?

When does the spine start to degenerate?
The spine starts degenerating somewhere between the ages of 20 and 25, explains Dr. Anand. But there’s a reason you don’t see most 20-somethings wincing from back pain: it takes a long time for spinal discs to wear down on their own. Normal aging isn’t the only cause of disc degeneration.
Does the spine acts as a shock absorber?
The intervertebral discs are flat, round “cushions” that act as shock absorbers between each vertebra in your spine.
What are the name of the first two vertebrae in your spine?
