Verified step by step guidance

Understand the question: The problem is asking about the type of joint responsible for the gliding motion of the wrist. This requires knowledge of joint classifications in the skeletal system.

Review the types of synovial joints: Synovial joints are classified based on their structure and the type of movement they allow. The main types include hinge joints, pivot joints, ball-and-socket joints, and plane (gliding) joints.

Focus on plane (gliding) joints: Plane joints are a type of synovial joint where flat or slightly curved surfaces slide over one another. These joints allow limited movement in multiple directions, such as gliding or sliding motions.

Apply the concept to the wrist: The wrist contains intercarpal joints, which are examples of plane (gliding) joints. These joints allow the small bones of the wrist (carpals) to glide against each other, enabling the gliding motion.

Eliminate incorrect options: Hinge joints (e.g., elbow) allow flexion and extension, pivot joints (e.g., neck) allow rotational movement, and ball-and-socket joints (e.g., shoulder) allow a wide range of motion. None of these match the gliding motion of the wrist, confirming that the correct answer is plane (gliding) joints.
