The cervical vertebra is the most flexible and active vertebral body in the spine, and it is also the part with the most work and the greatest stress. The cervical vertebra is also an important channel for nerves. Just like a two-lane expressway, it not only shoulders the responsibility of sending brain instructions to all parts of the body, but also sends various nerve information to the brain through the cervical vertebra.

So take good care of your cervical spine.

I hope it helps you.
