Upon which the atlas rotates, enabling the top to show, the axis of human neck includes a bony projection upwards. The skull sits on top enabling nodding activities, delivering a protected software because of it to secure on, and of somewhat compressed regions of the atlas. These associations are strengthened with sturdy muscles, putting further balance.
Don’t forget that this physiological design that is remarkable still allows the spinal cord that is essential to distribute of the brain.
