If I look at a “lateral” cervical spine (meaning from the side) x-ray- the spine should be in the shape of a “C”. If I look at a “AP” cervical spine (meaning from the front) x-ray- the spine should be straight up and down, with no curves. In between each of the bones, are the cervical spinal nerves, labels as in the diagram below asC1, C2, C3, C4, C5, C6, C7, and C8. The cervical spine is very important because it encompasses and protects the spinal cord, holds up the head and skull and also allows us to move our head: forward (flexion), look back (extension), bend from side to side (lateral flexion) and turn our head from side to side (rotation). Protection of the spinal cord is extremely important: messages from the brain travel through the spinal cord, out via nerves- innervating muscles, organs, blood vessels- this system controls how we walk, talk and basically do all of daily functions. What do these cervical nerves control? They control certain areas of the head, neck and upper back, including the arms and hands. More specifically:
Doctors often prescribe cervical traction to help get the curve back into the spine. This involveshome traction and also using pillows that will provide gentle traction while sleeping. Also surrrounding the cervical spine are tendons, ligaments and muscles- they allow for movement and prevent us from doing certain motions to prevent injury and pain. So there you have it- hopefully you understand the significance of the cervical spine- and why it is so important. The cervical spine is composed of bones c1-c7, nerves c1-c8, ligaments, tendons and muscles. Wrapping your head around all the complexities and functions of the cervical spine- can be a daunting task. Additional Resources:
