Which type of joint allows a gliding motion where two articular surfaces slide past each other?

• A. Plane (gliding) joint
• B. Ball-and-socket joint
• C. Hinge joint
• D. Pivot joint

Answer: (A)

Verified step by step guidance

1. Understand the types of synovial joints: Synovial joints are classified based on the movements they allow. Common types include plane (gliding), ball-and-socket, hinge, and pivot joints.
2. Define the plane (gliding) joint: This type of joint allows flat or slightly curved articular surfaces to slide past each other, enabling gliding movements. Examples include intercarpal joints in the wrist and intertarsal joints in the foot.
3. Compare the motion of other joint types: Ball-and-socket joints allow rotational and multi-directional movement (e.g., shoulder and hip joints). Hinge joints permit flexion and extension (e.g., elbow and knee). Pivot joints allow rotational movement around a single axis (e.g., the atlantoaxial joint in the neck).
4. Identify the correct joint type for gliding motion: Based on the definition and examples, the plane (gliding) joint is the type that allows articular surfaces to slide past each other.
5. Review anatomical examples: To reinforce understanding, consider anatomical examples of plane joints, such as the acromioclavicular joint in the shoulder or the joints between vertebral articular processes.
