The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. This action gives the head and neck a greater range of motion from side to side. The atlas does not look like a typical vertebra, with its ring-like structure and the absence of a body, which is actually fused to the axis. The temporal bone is located at either side of the skull beneath the temple. The purpose of this bone is support the weight of the head so it does not crush the spinal cord. The joint between the atlas and axis is a pivot type of joint. The most distinctive characteristic of this bone is the strong Odontoid Process(also known as the "dens") which rises perpendicularly from the upper surface of the body.It is a prominent rounded superior projection from the body.This tooth-like elevation serves a stable point around which the atlas bone rotates. Depending on the kind of Atlas misalignment, physiological lordosis or kyphosis of the spine may intensify sharply or disappear altogether. What is one function of compact bone? So symptoms can range from simple neck pain and soreness, to complete neurological and brain function disarray resulting in overcompensation of movement patterns and chronic pain.

The first vertebra has a great influence on the balance of the whole skeleton and is therefore directly responsible for an upright posture. The surface of the bone is covered by the periosteum, a membrane connecting the processes responsible for bone growth and callus formation in fractures.
