C1 is also know as
Atlas
C2 is also known as?
Axis
Describe why C1 is different?
The atlas is the most superior vertebra and supports the skull. It articulates with the occiput of the skull at the atlantooccipital joint, which is a synovial joint. This joint allows flexion of the neck
(upward and downward movement of the head or nodding).
Describe why C2 is different?
The axis is the second vertebra and articulates with the atlas at the atlantoaxial joint. This is a complex joint formed of three synovial joints and is classified as a pivot joint. This allows rotation of the head by allowing the skull to pivot on the odontoid process of the axial bone. It also stabilises the head in a neutral position.
