Atlas Vertebrae vs. Axis Vertebrae: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 26, 2023
Atlas vertebrae support the skull; axis vertebrae enable head rotation. Both are cervical vertebrae in the spine.
Key Differences
Atlas vertebrae and axis vertebrae are the first and second cervical vertebrae, respectively, crucial for head movement.
