We call the cervical spine the curve of life, because it's so critically important to how we feel and function physically and physiologically. It's important for overall health because all the nerves in your neck control and innervate so many body functions.The top two nerves that come out of the top two cervical bones, C1, C2, go back into your head. They control eye, ear, nose, and throat function. The mid cervicals are involved in innervating both the thyroid and the diaphragm. The thyroid plays a role in our sleep, mood, energy levels, metabolism and breathing function. The lower cervicals innervate your extremities.In your cervical spine, the top bone should be on top of your bottom bone, and we should have a negative 42-degree curve within the neck. This is designed so when you're upright, gravitational forces are in play. The weight of your head is carried in the back of the curve, where it should be, on all the extra bone.Continue reading Avoid Cervical Spine Problems with Chiropractic Care at Advanced Health Chiropractic South Loop.
