Which cervical vertebrae form the atlantoaxial joint?
C1 and C2 vertebrae
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. The C1 sits atop and rotates around C2 below.
Which cervical vertebrae form the atlantoaxial joint quizlet?
The atlantoaxial joint is a joint in the upper part of the neck between the first and second cervical vertebrae; the atlas and axis.
What type of joint is between C1 and C2 vertebrae?
The C1 and C2 vertebrae are connected in the back by a pair of facet joints. The ring-shaped atlas rotates around the dens, which is the peg-like bony projection of the axis.
What does the C1 and C2 vertebrae do?
The C1 and C2 vertebrae function together to give your head flexibility. With the atlas and axis relationship, you are able to swivel and rotate your head, as well as support your head. These two vertebrae are more responsible for the head’s rotational range of motion than from any other joint.
What forms Atlantoaxial joint?
The median atlantoaxial joint’s structure is formed by the dens of C1 vertebrae and two ligamentous structures anteriorly and posteriorly. [1] These structures are the osteoligamentous rings of the atlas and the transverse ligament, respectively.
Which is the atlantoaxial joint?
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….Atlantoaxial joint.

What are atlantoaxial joint?
The atlantoaxial joint is a type of synovial joint that is classified as a biaxial, pivot joint. This joint resides in the upper part of the neck between the first and second cervical vertebrae, also known as the atlas and axis, respectively.
What bones make up the atlantoaxial joint?
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 is Atlantoaxial?
The atlantoaxial joint is a complex joint between the atlas (C1) and the axis (C2). It is classified as a pivot joint. The lateral atlantoaxial joints are bilateral joints formed between the lateral masses of the atlas and axis. These joints are classified as gliding, or plane joints.
How many Atlantoaxial joints are there?
three atlanto
There are three atlanto-axial joints: one median and two lateral: The median atlanto-axial joint is sometimes considered a triple joint: one between the posterior surface of the anterior arch of atlas and the front of the odontoid process.
