Is atlantoaxial joint synovial?
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 kind of joint is atlanto axial?
The atlanto-axial joint is a joint between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint. There is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.
What type of movement does the atlantoaxial joint allow?
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.
Is atlanto occipital joint a pivot joint?
Cervical Region The atlanto-occipital joint (O-C1) acts as a pivot for the flexion/extension motion of the cranium, with 13 degrees average flexion/extension and 8 degrees lateral bending, thus allowing only a few degrees of axial rotation.
What type of synovial joint is atlanto occipital?
Synovial ellipsoid joint
Atlantooccipital joint
| Type | Synovial ellipsoid joint; biaxial |
|---|---|
| Articular surfaces | Occipital condyles, superior articular facets of atlas |
| Ligaments | Posterior atlantooccipital ligament, anterior atlantooccipital ligament |
| Innervation | C1 spinal nerve |
| Blood supply | Anastomosis between deep cervical, occipital and vertebral arteries |
What type of synovial joint is the elbow?
synovial hinge joint
Type of joint The elbow joint is a synovial hinge joint, similar to the ankle and knee joints. Two or more bones form hinge joints that move along an axis, rather than rotate like the hip joint. The distal humerus and proximal ulna are the primary elbow joint bones.
What type of synovial joint is the atlanto occipital joint?
Which type of joint is present between atlas and axis?
Pivot joint
The joint between the atlas and axis is called Pivot joint. It allows the head to turn from side to side.
What type of synovial joint is the atlanto-occipital joint?
What movement occurs at the atlanto-occipital joint?
flexion and extension
The movements permitted in this joint are: (a) flexion and extension around the mediolateral axis, which give rise to the ordinary forward and backward nodding of the head. (b) slight lateral motion, lateroflexion, to one or other side around the anteroposterior axis.
What type of synovial joint is the atlanto occipital?
What type of joint is the atlas?
The atlas and axis form the atlanto-axial joint, which allows head rotation. If you shake your head as if to say “no,” that is head rotation. The atlanto-axial joint is a compound synovial joint.
What is atlanto-occipital joint?
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).
Is atlanto-occipital joint a saddle joint?
The atlanto-occipital joint (Capsula articularis atlantooccipitalis) is an articulation between the atlas bone and the occipital bone. It consists of a pair of condyloid joints. It is a synovial joint….

What kind of synovial joint is found between the skull and atlas?
Atlantooccipital joint
| Type | Synovial ellipsoid joint; biaxial |
|---|---|
| Articular surfaces | Occipital condyles, superior articular facets of atlas |
| Ligaments | Posterior atlantooccipital ligament, anterior atlantooccipital ligament |

Is the atlas and axis a hinge joint?
Joint between atlas and axis vertebrae is an example of pivot joint. It is a type of synovial joint. This joint is characterised with central bony pivot surrounded by collar of bone and ligament. This type of joint permits supination, rotation and pronation types of movements.
What type of synovial joint is the atlanto-occipital?
What type of joint is between the axis and atlas?
