Which type of joint allows for rotation of the head?

• A. Ball and socket
• B. Hinge
• C. Pivot
• D. Gliding

Answer: (C)

The type of joint that allows for rotation of the head is the pivot joint. This joint structure features a cylindrical bone that rotates within a ring formed by another bone and surrounding ligament. In the case of head movement, the pivot joint between the first and second cervical vertebrae (the atlas and the axis) allows for the head to rotate side to side, as well as nodding motions. This unique design enables a range of rotational movements that are essential for head mobility, making the pivot joint crucial for actions such as shaking the head to indicate "no." The specific anatomy of a pivot joint facilitates this rotational movement more effectively than other types of joints.
