Gliding joint

Gliding joint is a type of joint found in the human body. It is also known as a plane joint or arthrodial joint. Gliding joints allow for a wide range of motion in multiple directions without rotation. They are formed when two flat or nearly flat bone surfaces come together, such as in the carpals of the wrist or tarsals of the foot.

Structure

The structure of a gliding joint is simple. It consists of two opposing flat bone surfaces of about the same size. These surfaces are covered with articular cartilage, a smooth, slippery substance that allows the bones to glide over each other with minimal friction. The joint is surrounded by a fibrous joint capsule that is filled with synovial fluid, which further reduces friction and nourishes the cartilage.

Function

The primary function of a gliding joint is to allow for movement. This type of joint allows for gliding movements in any direction along the plane of the joint. The range of motion is limited only by the surrounding structures such as ligaments and muscles. Gliding joints are found in many areas of the body, including the wrists, ankles, and spine.

Clinical significance

Gliding joints, like all joints, can be affected by various conditions. Arthritis, a condition characterized by inflammation of the joints, can cause pain and limited mobility in gliding joints. Osteoarthritis, a type of arthritis caused by wear and tear, is common in gliding joints due to the constant movement and pressure on these joints.
