In the cervical spine you have 7 spinal bones or vertebrae. At each level exits out cervical nerve roots. They travel off of the spinal cord and branch into more nerves. If your neck range of motion is compromised and pressure builds up on nerves you can get: neck pain, headaches, even arm pain or something worse.
As far as the motion goes, you should be able to flex your chin to your chest, you should be able to look up at the ceiling (cervical extension), turn your chin to your shoulder, and tilt your ear nearly to your shoulder also. The normal ranges of motion in degrees are as follows:
Flexion: 60 degrees Extension: 50 degrees Lateral Tilting: 45 degrees Rotation (turning head to each side): 80 degrees
