Which joint type allows sliding motion between adjacent bones such as in the neck?

• A. Hinge Joint
• B. Pivot Joint
• C. Sliding Joint
• D. Ball-and-Socket Joint

Answer: (C)

Understanding joint types by how they move helps here. Sliding, or plane, joints have flat or gently curved articular surfaces that glide past each other with small, smooth motions. This enables the bones to slide relative to one another rather than rotate or hinge, which is exactly the type of movement described for adjacent bones in the neck region. In the neck, the small sliding movements occur between the vertebrae at the facet joints, allowing subtle gliding that contributes to overall neck flexibility. Other joints produce movement in different ways: hinge joints allow bending and straightening in one plane (like an elbow), pivot joints enable rotation around a single axis (like turning the head at the atlas–axis), and ball-and-socket joints permit movement in multiple directions including rotation (like the shoulder). So, the best fit for sliding motion between adjacent bones is a sliding (plane) joint.
