MBBS QUESTION #10149
Question 1
The median atlantoaxial joint (between the dens of C2 and the anterior arch/transverse ligament of C1) permits rotation of the head and is best classified as which type of synovial joint?
  • Hinge joint
  • Pivot joint✔️
  • Saddle joint
  • Ball-and-socket joint
Correct Answer Explanation
A pivot joint allows uniaxial rotation of one bone around a central axis formed by another, exactly as the dens of C2 rotates within the ring formed by the atlas and transverse ligament — the mechanism permitting side-to-side head rotation.
