What are sliding joints?

A gliding joint, also known as a plane joint or planar joint, is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. 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.
