C1 or atlas: The Atlas is the topmost vertebra, and - along with C2 - forms the joint connecting the skull and spine. Its chief peculiarity is that it has no body, and this is due to the fact that the body of the atlas has fused with that of the next vertebra.
C2 or axis It forms the pivot upon which C1 rotates. The most distinctive characteristic of this bone is the strong odontoid process (dens) which rises perpendicularly from the upper surface of the body. The body is deeper in front than behind, and prolonged downward anteriorly so as to overlap the upper and front part of the third vertebra.
the brain stem is an important factor. damage or harm to first and second. (even to 1-7) dramatical harm can cause numerous neurological problems
What else can I help you with?
The cervical spine is made up of how many cervical vertebrae?
The cervical spine is made up of seven cervical vertebrae. These are numbered(C1-C7) and are the smallest of the true vertebrae. The third through sixth cervical vertebrae have characteristics in common. The first, second, and seventh are considered special cervical vertebrae, and have different characteristics.
What bone feature of the second cervical vertebrae articulates with the first cervical vertebrae?
The odontoid process, also known as the dens, is the bone feature of the second cervical vertebrae that articulates with the first cervical vertebrae. This connection forms the atlantoaxial joint, which allows for rotation of the head.
How many cervical vertebrae are there?
the first 7 vertebrae, the neck vertebrae, are considered to be cervical
Which cervical vertebrae form the atlantoxial joint?
The atlantoxial joint is formed by the first and second cervical vertebrae, known as the atlas (C1) and axis (C2) respectively. It allows for rotational movement of the head.
What is the first cervical vertebrae in the neck?
The atlas is the uppermost vertebrae in the neck.
What is the first bone of the cervical column?
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.
What are the different vertebrae in the back bone?
You have 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumber vertebrae, 1 sacrum and 1 coccyx. The first cervical vertebra is called as atlas vertebra. The second one is called as axis vertebra.
Cervical vertebrae?
First seven vertrebrae. Develps an anterior curvature. Labeled C1 to C7. Supports the weight of the head. First two vertebrae have special names.
What is second vertebrae called?
The name of the second vertebrae is called the axis.
What is the vertebra of the neck?
The vertebrae in the neck are called cervicle vertebrae. There are 6 of them altogether. The first two (going downward from the skull) are called the atlas and the axis. The rest are just name by their order. Eg: C1 (Atlas), C2 (Axis), C3, C4.....
What regions of the vertebral column do not contain intervertebral discs?
intervertebral discs are not found in the sacrum and coccyx, where the vertebrae have fused, or between the first and second cervical vertebrae.
What vertebrae contains the joint that allows you to rotate your head no?
The cervical(neck) vertebrae. The joint formed by C1 and C2, also known as the atlas and axis.
