Ventral Arches
Actually, the first cervical vertebra is called the atlas, not the axis. The axis is the second cervical vertebra that forms a pivot joint with the atlas, allowing for rotation of the head from side to side.
The first cervical vertebra is called the atlas, after the Greek mythological figure who held up the heavens. The second cervical vertebra is called the axis, as it allows the head to rotate from side to side.
Atlaswrong . the correct answer is axis (http://en.wikipedia.org/wiki/Axis_(anatomy)) "It forms the pivot upon which the first cervical vertebra (the atlas), which carries the head, rotates."
No it doesn't. The atlas is the first cervical vertebra and the only one with no spinous process.
The axis is the second cervical vertebra (C2) in the neck region, which forms a joint with the first cervical vertebra (C1) called the atlantoaxial joint. This joint allows for rotation of the head from side to side, giving us a wider range of movement in the neck.
The vertebrae that contain a transverse foramen, bifid spine, and small body is the cervical vertebrae. The seventh cervical vertebra (C7), also known as the vertebra prominens, typically has these characteristics.
Most vertebrae have 3 processes. The spinous process, which is the one that comes straight off of your vertebral column, can actually be felt . You can feel this one particularly well at the base of your neck (this is the 7th Cervical vertebra, also known as Vertebra prominens). The very first vertebra, C1, also known at Atlas, does not have a spinous process. Each vertebra has two transverse processes which are on either side of the spinous processes. All of these processes are important for muscle attachments for movement of the head, neck and torso.
The occipital condyles of the occipital bones articulate with the first cervical vertebra.
They originate from the transverse processes from the cervical vertebrae of C2 to C7 and insert onto the first and second ribs. Thus they are called the lateral vertebral muscles.

Yes, the atlas is classified as the first cervical vertebra (C1) in the human spine. It is named after the Greek titan Atlas who was condemned to hold up the sky, symbolizing its role in supporting the head.
The first cervical vertebra, called C1 or the atlas, articulates with the occipital bone.
The vertebrae are the backbones. The cervical vertebrae are at the top. The skull rests on and turns on the first cervical vertebra, called "C1". C1 is tied to the second cervical vertebra, called "C2", which allows, the head to turn far to each side by a special arrangement of bone and ligaments. C3, C4, and C5 are regular vertebrae, but smaller than those further down the spine.

It is the the most superior (first) cervical vertebra of the spine.
