Biaxial joints allow for movement in two planes or axes. A common example of a biaxial joint is the wrist, which allow for movement side to side, and also allows for movement up and down. It can be difficult to determine whether a joint is biaxial or multiaxial, because when the biaxial joint moves in both directions at the same time, it appears to have the multiaxial quality of being able to move in any plane or axes.
Joints are located where two bones connect. They allow movement and provide mechanical support.
Specifically ellipsoidal joints are joints in the body which by their shape and ligaments allow only flexion, extension, abduction, and adduction.Rotation is impossible. The wristis an example of this type of joint.
Movable joints enable the body to make a wide range of movements.
The overall purpose of a joint is to provide movement . Differing types of joints allow for differing movements; a hinge joint allows motion in one direction whereas a pivot joint allows rotating or twisting motion.

Plane or gliding joints that allow sliding or back and forth motion and twisting movements.
Joints are located where two bones connect. They allow movement and provide mechanical support.
Examples of ellipsoidal joints in the human body include the wrist joint and the base of the fingers. These joints allow for movement in two planes - flexion/extension and abduction/adduction - as well as circular movements.

There are several ways in which joints are classified. The main classifications are in regard to how much they move. The classical terms are Synarthrotic, Amphiarthrotic, and Diarthrotic, where the Diarthrotic are the most movable. The diarthrotic joints are also called freely moving, or synovial joints. These can be classified by how they move. There are monoaxial joints, which move in one plane, or around a central axis. Then there are biaxial joints that move in two planes of movement. And, finally, there are the multiaxial (sometimes called triaxial) joints that move in more than two planes. The monoaxial joints can be subdivided into hinge and pivot joints. The biaxial joints can be subdivided into ellipsoidal and saddle. And, the multiaxial joints can be subdivided into gliding and ball-and-socket joints.
