name the articulation between a C1 vertebrae and occipital b

Solution

The articulation between the C1 vertebrae (Atlas) and the occipital bone is called the atlanto-occipital joint, made up of a pair of condyloid joints.

This joint is a type of synovial joint. It functions as a function as bilaterally symmetrical ellipsoid synovial joints between C0 and C1. The joint capsule is supported by any accessory ligaments, and structural stability is mainly provided through Posterior atlanto-occipital ligament and the Anterior atlanto-occipital ligament. The joint provides two degrees of freedom, namely flexion/extension and lateral flexion/conjunct rotation.
