Anatomical terminology [edit on Wikidata]

In animal anatomy, a pivot joint (trochoid joint, rotary joint or lateral ginglymus) is a type of synovial joint whose movement axis is parallel to the long axis of the proximal bone, which typically has a convex articular surface.

According to one classification system, a pivot joint like the other synovial joint —the hinge joint has one degree of freedom.^[1] Note that the degrees of freedom of a joint is not the same as a joint's range of motion.
