Atlanto-occipital joint: Bones, ligaments, movements - Kenhub
2023年8月3日 · 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).
Atlanto-occipital joint - Physiopedia
The atlanto-occipital joint also known as the C0-C1 is a paired symmetrical articulation between the cervical spine and the base of the skull. 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] .
Atlanto-occipital joint - Anatomy, Ligament, Muscles, Movement
2023年3月29日 · The primary movement of the atlantooccipital joint is flexion-extension. This action allows nodding of the head, as seen when indicating permission (the “yes” movement). Functionally, these 2 ellipsoid joints (condyloid joint) accomplish their actions simultaneously and thus can be mechanically evaluated as a single joint.
Atlanto-occipital joint - Wikipedia
The atlanto-occipital joint (Articulatio 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.

2023年11月9日 · While the cervical spine can undergo flexion, extension, rotation, and side-bending, each individual cervical joint has a primary motion. C1, the atlas, has no spinous process and articulates with the occipital condyles of the occiput bone of the skull, forming the occipital-atlanto (OA) joint.
Atlanto-occipital articulation | Radiology Reference Article ...
2024年1月12日 · 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).
Atlanto-occipital joint | Encyclopedia | Anatomy.app | Learn …
Atlanto-occipital joint movements. The atlanto-occipital joints are biaxial, and they allow movements in two plains. These articulations are responsible for flexion/extension and limited lateral flexion (abduction/adduction), and minimal rotation of the head.

2018年11月20日 · The O-C1 joint or atlanto-occipital joint is located between the superior concave sockets of the atlas (C1) and the occipital condyles of the skull. It is a very stable joint due to the design of the articular surfaces and provides stability for the transfer of weight from head to neck and to balance the head on the neck.
Atlantooccipital Joint - an overview | ScienceDirect Topics
The atlanto-occipital joint, formed between the occipital condyle and lateral masses of C1, allows no rotation but free flexion/extension and some lateral flexion. There are three atlantoaxial joints.
Atlanto-Occipital Joint - Radiologica
2021年9月6日 · The atlantooccipital joints (less commonly known as the C0-C1 joint) are a symmetrical condyloid synovial joint between the occipital bone (C0) and first cervical vertebra (atlas/C1), classified as a biaxial, pivot joint.
