Where is the atlanto axial joint located?
cervical spine
The C1 C2 spinal motion segment, also called the atlantoaxial joint, is located in the upper portion of the cervical spine. It consists of the C1 and C2 vertebrae, and the anatomical structures connecting them. This segment provides rotational motion, supports the head, and protects the spinal cord and nerve pathways.
What is atlanto axial?
The atlanto-axial joint is a joint in the upper part of the neck between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint.
What kind of joint is the joint between C1 and C2?
The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Together they form the atlantoaxial joint, which is a pivot joint.
What kind of joint is atlanto occipital joint?
condyloid synovial joints
The atlanto-occipital articulation (also known as the C0-C1 joint/articulation) is comprised of a pair of condyloid synovial joints that connect the occipital bone (C0) to the first cervical vertebra (atlas/C1).
Where is C1 and C2 located?
The C1 and C2 vertebrae are the highest of the spinal vertebrae and are located at the very top of the neck, connecting the head to the spine. The C1 vertebrae is named atlas and the C2 vertebrae is named axis.
What is atlas and axis?
The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are part of the seven cervical vertebrae. The atlas is the top-most bone, sitting just below the skull; it is followed by the axis. Together, they support the skull, facilitate neck movement, and protect the spinal cord.
What is atlas and axis joint?
Atlas and axis joint: The joint between the atlas and axis bones. The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates. The joint between the atlas and axis is a pivot type of joint. It allows the head turn from side to side.
Is the atlantoaxial joint a facet joint?
Atlantoaxial (C1-C2) facet joint osteoarthritis: a distinctive clinical syndrome. Arthritis Rheum.
What type of joint is the median atlantoaxial joint?
synovial joint
The median atlantoaxial joint is a pivot type of synovial joint. Broadly, the joint is formed by the dens of axis (odontoid process) surrounded by an osteoligamentous ring composed of the anterior arch of atlas anteriorly and the transverse ligament of atlas posteriorly.
What’s the joint between axis and atlas?
The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates. The joint between the atlas and axis is a pivot type of joint. It allows the head turn from side to side. It is also called the atloaxoid joint.
How is the median atlanto axial joint best classified?
The median atlantoaxial joint is formed between the dens of axis and an osteoligamentous ring of the atlas anteriorly and transverse ligament posteriorly. It is classified as a pivot joint.
What type of axial movement does the atlanto-occipital joint have?
flexion-extension
The principal movement at the atlantooccipital joint is flexion-extension. This movement permits nodding of the head, as seen when indicating approval (the “yes” movement)….Atlantooccipital joint.
