Quick Answer: What Is The Atlas Anatomy?

What is the Atlas bone function?

The atlas is ring-shaped and has the important task of supporting the head. It’s also responsible for facilitating movement in head and neck. When you nod your head “yes,” that’s the atlas at work. It serves as a pivot, and it allows your head to move forward and backward.

What is unique about the Atlas bone?

Atlas. The atlas is the first cervical vertebra and articulates with the occiput of the head and the axis (C2). It differs from the other cervical vertebrae in that it has no vertebral body and no spinous process. Instead, the atlas has lateral masses which are connected by an anterior and posterior arch.

What bones does the Atlas articulate with?

THE ATLAS. The first cervical vertebra, or atlas, articulates with the occiput rostrally and the axis caudally. It consists of two articulating lateral masses that are connected anteriorly and posteriorly by neural arches (Fig. 2-3).

Can you adjust your own Atlas?

With our exercises’ help, you can usually make an atlas correction yourself by loosening and stretching the muscles and fasciae in this area. An atlas blockage can also be located between the atlas vertebra and the underlying axis.

Why is it called the atlas bone?

In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck. It is named for Atlas of Greek mythology because, just as Atlas supported the globe, it supports the entire head.

Does the atlas have a body?

The atlas is ring-shaped and does not have a body, unlike the rest of the vertebrae. Fused remnants of the atlas body have become part of C2, where they are called the odontoid process, or dens.

How do I adjust my atlas bone?

To adjust your atlas, we use an Atlas Orthogonal Precision Adjusting Instrument. This instrument may sound intimidating, but it’s actually completely painless – literally, you won’t feel a thing. You simply lie on your side and the doctor places the tip of the instrument just below your earlobe.

What is the difference between Atlas and Axis?

The atlas is the first cervical (neck) vertebra which is just under the head; it is named for Atlas, the Greek god who supported the world on his shoulders. The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates. It allows the head turn from side to side.

Is C1 same as Atlas?

The atlas (plural: atlases) is the first cervical vertebra, commonly called C1. It is an atypical cervical vertebra with unique features. It articulates with the dens of the axis and the occiput, respectively allowing rotation of the head, and flexion, extension and lateral flexion of the head.

What is 7th cervical?

The 7th cervical (C7) vertebra is the largest and most inferior vertebra in the neck region. Unlike the other cervical vertebrae, the C7 has a large spinous process that protrudes posteriorly toward the skin at the back of the neck.

Is the atlas an irregular bone?

Irregular bones have complicated shapes that cannot be classified as “long”, “short” or “flat”. Their shapes are due to the functions they fulfill within the body e.g. providing major mechanical support for the body yet also protecting the spinal cord (in the case of the vertebrae). Examples: Atlas bone.

Why is C2 called axis?

C2 (cervical vertebra): C2 is the symbol for the second cervical vertebra, which is also called the axis. It is so- named because the uppermost cervical vertebra ( called the atlas) rotates about the odontoid process of the second cervical vertebra.

What is above Atlas?

The Atlas (the first cervical vertebra – C1) differs from the other cervical vertebrae in that it has no body or spinous process. It is comprised of two bony arches with two bony masses laterally. It articulates with the Occiput above and C2 (the Axis) below.

Is there cartilage between Atlas and Axis?

It consists of no fewer than four distinct joints. There is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.
