Types of Joints: Synarthroses and Diarthroses

Synarthroses joints allow a wide range of movement.

The vertebral symphisial joints permit very limited movement.

Pivot joints allow movements on multiple planes.

Saddle joints are examples of uniaxial joints.

Ball-and-socket joints allow a wide range of movement, including rotation.

The knee joint is an example of a ball-and-socket joint.

Synarthroses joints allow very little or no movement.

Hinge joints, like those of the knee, allow movements on only one plane.

Saddle joints, like those of the ankle, have concave and convex articular surfaces of bones in two directions.

Multiaxial joints, like ball-and-socket joints, allow a wide range of movement including rotation.

The hip joint is an example of a ball-and-socket joint.

Pivot joints, like those between the radius and ulna, allow rotation only around the axis.
