2022年12月1日 · There is a smooth, kidney-shaped depression or facet on the upper surface (superior articular facet) of each lateral mass where the bone articulates with the condyles of the skull bone occipital to form the atlanto-occipital joint. This joint allows you to move your head to extend and flex the neck.

2023年12月6日 · atlanto-occipital joint: hyaline-covered synovial joint between the occipital condyle and concave facet of the lateral mass of the atlas. Covered by a capsule and innervated by C1, this joint allows for flexion, extension and lateral flexion.
Atlanto-occipital joint - Physiopedia
It includes the occipital condyle and the superior articular surfaces of the first cervical vertebra (C1 or Atlas), allowing flexion, extension and lateral tilt of the head [2]. Along with the atlantoaxial joint, it makes up a group called the craniovertebral joints. Occipital condyles and a superior articular facets of the atlas [1].
Anatomical structure of the atlas - Kenhub
2023年10月30日 · The atlas articulates superiorly with the occipital condyles found on each side of the foramen magnum of the skull. Inferiorly, it articulates with the second cervical vertebra (C2), which is also known as the axis .
Atlanto-occipital joint: Bones, ligaments, movements - Kenhub
2023年8月3日 · The atlantooccipital joint is the synovial articulation between the occipital bone and the first cervical vertebra (atlas). The articular surfaces are oval (elliptical) in shape and reciprocally concave-convex, with the concave articular facets of C1 vertebra articulating with the convex surfaces of the occipital bone.

Superiorly the atlas articulates with the occiput to form the Atlanto-occipital joint which allows the head to nod up and down on the vertebral column. Inferiorly the atlas articulates with the dens which acts as a pivot that allows the atlas and attached head to rotate on the axis.
Atlas Bone Anatomy - GetBodySmart
2022年11月2日 · On the superior surface of the atlas bone are a pair of concave facets. The facets articulate with rounded condyles on the underside of the skull’s occipital bone. This junction allows the head to nod up and down. Directly below the atlas bone is the axis bone (C2). Pivot and gliding joints linking the two bones allow the head to move side-to-side.
