What is the Function of the Atlas and Axis?

Atlas and Axis Bones

When you think about the atlas and the axis – do you think about world geography? A globe? Or a pair of very important bones?

The first seven vertebrae in the spine make up what is known as the cervical spine. It begins right below the neck and ends where the middle 12 vertebrae, or thoracic spine, begin.

The two uppermost vertebrae at the top of the cervical spine are different from the others in this grouping because they provide the neck with the ability to rotate. The atlas (C1) is the first cervical vertebra; it is located between the skull and the remaining vertebrae of the spine. Directly below the atlas is the axis (C2). Special ligaments link these two vertebrae, allowing a great deal of rotation between them.

When we talk about “head rotation,” we are really referring to the atlas rotating on the axis. These two bones, working in tandem, give your head its ability to turn from side to side.

Because the cervical spine is so flexible, it is quite susceptible to injury. When you hear about whiplash injuries sustained in a car crash, these two vertebrae are often involved. When you stop to consider that this relatively small area of the spine supports the head, it is easy to understand how abrupt head movement could cause damage, let alone a car crash with a violent head jerk!

Dr. Vanessa Asks some important questions of interest to New Braunfels residents - Chiropractor New Braunfels Dr. Vanessa Asks...

Why are some people allergic to pollen and others aren't?
It's not the pollen. Chiropractors know that if it were, everyone would be allergic to pollen, nuts and pet dander. But that's not the case. It's the person, not the pollen! If you live in New Braunfels and your stress levels are high, then each year the grass, the trees or the weeds put your nervous system over the top. Many report that chiropractic care helps reduce the frequency and severity of their allergic response.
What's the difference between a "good" drug and a "bad" drug?
As a chiropractor, I see the use of many drugs (legal or illegal) as merely symptom treating. Worse, virtually every drug produces unwanted effects. The effects of chiropractic are largely positive effects. If you're a New Braunfels parent, consider carefully before giving your child a cough medication, cold remedy or pain reliever so this sort of question doesn't arise in the first place.
