What type of joint is formed between the atlas and odontoid process?
Wiki User
∙ 13y ago
The Odontoid Process is articulated with the C2 vertebrae [Axis] & is a synovial joint-type. The atlas [C1] is also a synovial-type articulation, but is associated with the Occipital Condyle [directly with the skull]

Its oval-shaped protrusions articulate with the atlas?
The condyles of the occipital bone articulate with the atlas.
Are axis and atlas part of cervical vertebra?
The Atlas is designed to allow a nodding movement, whilst the axis below it has the odontoid peg on it to allow shaking, or rotational movement of the skull.
What are the two most superior vertebrae?
The two most superior vertebrae are CERVICAL vertebrae 1 and 2 (C1 and C2). They are also known as the Atlas (C1) and Axis (C2). These two vertebra join together to form the atlantoaxial joint, which helps with the movement of the neck. A structure on the axis called the dens (odontoid process) fits through a foramen (hole) in the atlas to join them together.
How many bones in the cervical vertebrae?
There are seven cervical (C1-C7) vertebrae. The top two are unique in form and number three through seven are similar in morphology. The uppermost is the atlas (C1) which supports the skull, and the next is the axis (C2), where much if the rotation takes place. The body of the atlas is the odontoid process of the axis (c2), and the atlas (c1) rotates around this.
What movement of the head will be allowed by the atlas?
The odontoid of the second cervical vertebrae (ie: the axis) forms a joint with the anterior ring of the first cervical vertebrae (ie: the atlas). This joint is primarily responsible for allowing the head to rotate from side to side as if you were nodding "no" to someone. See the related link for further information.
Where did the odontoid process come from developmentally?
from the atlas
Its oval-shaped protrusions articulate with the atlas?
The condyles of the occipital bone articulate with the atlas.
Where is the odontoid process?
This is also knows as the Dens.. It is located with the Atlas (c1) and the Axias (c2) it helps with the rotation of the head.
Bone that has the odontoid process?
This is also knows as the Dens.. It is located with the Atlas (c1) and the Axias (c2) it helps with the rotation of the head.
What is the dens odontoid process?
Since the dens is part of the Axis vertebra (and project up in the first vertebra, the Atlas vertebra that supports the skull) it is called the Dens Axis
How many vertebra in the cervical?

Why is an intervertebral disc not present between C1 and C2?
yes. the atlas and axis, or C1 and C2, do not have an intervertebral disc, nor an intervertebral foramen, between them. C1 looks like an oval. it has two lateral masses (no vertebral body) where it makes contact with the occiput and C2. the inferior articular facets of the C1 and the superior articular facets of C2 form 2 joints, one on each side. there is also a third joint formed by the dens, or odontoid process, of C2 and the interior of the anterior arch of C1. this is the joint you use to shake your head "no".
Which type of joint is your neck joint?
Pivot joint formed between the atlas and the axis (first two vertebrae)
Why are atlas sacral and urostyle classified as atypical vertebrae?
The first cervical vertebra (C1) and the second cervical vertebra (C2) are atypical vertebrae due to the fact that the structures of these vertebrae are unlike the rest of the cervical spine vertebrae. The C1, also known as the atlas, is a ring-like structure which allows the beginning of the spinal cord to pass through form the base of the skull. The C2, also known as the axis, is the largest of the cervical vertebrae in vertical dimension as it contains an extension of bone called the odontoid process that extends up into the ring of the atlas. This area of the neck is the most freely moveable as the majority of side-to-side rotation occurs at C1 on C2 and is also most important neurologically as this area of the spinal cord controls heart, breathing and posture of the human being.
