Between the atlas and axis vertebrae, what form of joint is found?

Answer 1

Pivot joint:

1. In vertebrate anatomy, a pivot joint, also known as a rotary joint or trochoid joint, is a freely mobile (diarthrosis) that enables only circular movement around a single axis.
2. The second cervical vertebra is the axis.
3. The atlas spins around the odontoid process.
4. The joint between the atlas and the axis is the pivot joint.
