Plane joint

What are examples of a plane joint? Is gliding joint and plane joint the same? Where are plane joints found? Are plane joints multiaxial?


A plane joint (arthrodial joint , gliding joint , plane articulation) is a synovial joint which, under physiological conditions, allows only gliding movement.

Plane joints permit sliding movements in the plane of articular surfaces. The intervertebral joints are this type, and many of the small bones of the wrist and ankle also meet in gliding joints. Called also arthrodial joint and plane joint.


Examples are the elbow and the interphalangeal joints of the fingers. The jaw is primarily a hinge joint but it can also move somewhat from side to side. Movements Under normal conditions plane joints only permit sliding movement in the same plane as the articular surfaces, and do not allow movement in any other plane.


A synovial joint in which the opposing surfaces are nearly planes and in which there is only a slight, gliding motion. Gliding joints allow the bones to glide past one another in any direction along the plane of the joint — up and down, left and right, and diagonally.

The plane , or arthrodial, joint has mating surfaces that are slightly curved and may be either ovoid or sellar. Only a small amount of gliding movement is found. A plane joint ( arthrodial joint , gliding joint , plane articulation) is a synovial joint which, under physiological conditions, allows only gliding movement. Vertical section through the articulations at the wrist, showing the synovial cavities. The joint surfaces resemble geometric figures and may be spherical, ellipsoidal, saddle-shape or flat.


Joints may be movable, for example, the spherical shoulder joint , or immovable, for example, the joint between a rib and the sternum. The range of joint movements is measured in the degrees of the angles formed by the articulating bones. The plane joint is a part of the skeletal system and is held together by ligaments, which stabilize it. Muscles that pass across a plane joint also help to stabilize it.


Hyaline (articular) cartilage coats and separates the ends of bones that form a plane joint. A plane joint is a synovial joint which, under physiological conditions, allows only gliding movement. A plane joint , also called a gliding joint , are places where the bones meet and slide past one another on a flat edge. The opposed surfaces of the bones are flat or almost flat, with movement limited by their tight joint capsules.


Between each of the bones, we find small padding of cartilage and other tissues to help with that smooth, fluid motion we enjoy. Movements of the human body are often described in terms of the ‘plane’ in which they pass through. There are three planes of the human body, these planes are shown in the following table.


The frontal plane passes through the body from left to right, dividing the body into anterior and posterior portions.
