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 opposed surfaces of the bones are flat or almost flat, with movement limited by their tight joint capsules.
The acromioclavicular joint allows the arm to be raised above the head. This joint functions as a pivot point (although technically it is a gliding synovial joint), acting like a strut to help with movement of the scapula resulting in a greater degree of arm rotation.
A multiaxial joint, such as the hip joint, allows for three types of movement: anterior-posterior, medial-lateral, and rotational. A multiaxial joint (polyaxial joint or triaxial joint) is a synovial joint that allows for several directions of movement. [9] In the human body, the shoulder and hip joints are multiaxial joints.

The cricoarytenoid joint allows for rotation and gliding motion. [1] The extent of rotation is significant, while the extent of gliding is limited. [1] The cricoarytenoid joint controls the abduction and adduction of the vocal cords. [1] It is moved by many of the intrinsic muscles of the larynx. [2]
Type A is found in 56% of females and 66% of males. There is a well-defined "facet". It has a tight capsule and ligaments with either a concavity or a small groin directed from posterior superior to anterior inferior. Horizontal translational movement is about 3.0 mm, vertical gliding about 2.5 mm with great movement horizontally than vertically.
Other joints such as sutures between the bones of the skull permit very little movement (only during birth) in order to protect the brain and the sense organs. [3] The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and ...
The acromioclavicular joint provides the ability to raise the arm above the head. This joint functions as a pivot point (although technically it is a gliding synovial joint), acting like a strut to help with movement of the scapula resulting in a greater degree of arm rotation.
The Joints are structures that connect individual bones and may allow bones to move against each other to cause movement. There are three divisions of joints, diarthroses which allow extensive mobility between two or more articular heads; amphiarthrosis, which is a joint that allows some movement, and false joints or synarthroses, joints that ...
