Axis. Anterior aspect.
The most prominent feature of that vertebra is the teeth-shaped process — dens axis.
The list of terms:Corpus vertebrae – Body of vertebra Dens axis – Dens of axis Apex Dentis – Apex of dens Facies articularis anterior – Anteriror articular surface of dens Processus articularis superior – Superior articular process Processus articularis inferior – Inferior articular process Processus transversus – Transverse process
Axis. Superior aspect.
Another feature of this vertebra is the convex shape of the articular surface of processus articularis superior, which is not congruent to the adjacent articular surface of the axis, allowing some lateral bending and flexion-extension movements between atlas and axis*.
The list of terms:Corpus vertebrae – Body of vertebra Dens axis – Dens of axis Arcus vertebrae – Vertebral arch Lamina arcus vertebrae – Lamina of vertebral arch Foramen vertebrale – Vertebral foramen Apex Dentis – Apex of dens Facies articularis anterior – Anterior articular surface of dens Processus articularis superior – Superior articular process Processus articularis inferior – Inferior articular process Processus spinosus – Spinous process Processus transversus – Trnasverse process
Axis. Lateral aspect. Compared with other cervical vertebrae, the axis has two extra articulatory surfaces on both sides of the dens – facies articularis anterior & posterior.
