What type of joint allows one bone to slide over another; examples neck and vertebrae?

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

Answer: (B)

Movement where one bone slides over another is characteristic of sliding (plane) joints. These joints have flat articular surfaces that come into contact and allow small, gliding movements with little or no angular change. In the neck and along the vertebral column, the facet (zygapophyseal) joints between neighboring vertebrae are plane joints, enabling the vertebrae to glide past each other as the neck bends and twists. Hinge joints restrict movement to one plane of flexion and extension, pivot joints allow rotation around a single axis, and ball-and-socket joints permit movement in many directions including rotation. Therefore, the sliding joint best fits the described motion.
