What type of joint is formed between the atlas and odontoid process?
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]
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.
The axis is the only vertebra with?
The axis is the second cervical vertebra (C2) and has a unique feature called the odontoid process or dens, which projects superiorly from its body. This structure allows the atlas (C1) to pivot around the axis, enabling the movement of the head from side to side.
Nodding your head yes represents movement of which type of joint?
The atlanto-occipital joint. This is the articulation between the atlas (C1) and the occipital bone.
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.
What is the dens superior articulation?
The dens superior articulation refers to the joint formed between the dens (or odontoid process) of the second cervical vertebra (C2, also known as the axis) and the anterior arch of the first cervical vertebra (C1, or atlas). This articulation allows for the rotation of the head and neck, facilitating movements such as turning the head side to side. It is a pivotal joint in the cervical spine, playing a crucial role in maintaining stability and mobility.
What type of joint is formed between the atlas and odontoid process?
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]
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.
What is o odontoid?
The odontoid process, also known as the dens, is a projection of the axis bone in the vertebral column. It is an important structure that helps stabilize the atlas bone (C1) and allows for rotational movement of the head. Injuries to the odontoid can be serious and may require surgical intervention.
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".
Where did the odontoid process come from developmentally?
The odontoid process, also known as the dens, is derived from the first cervical vertebra (C1), which is called the atlas. During development, the dens of the axis (C2) separates from the atlas and forms as a distinct bony process.
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.
How many vertebra in the cervical?
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.
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.
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.
