what type of movement does pivot cause
A pivot joint (trochoid joint, rotary joint, Lateral Ginglymus) is a type of synovial joint.In pivot joints, the axis of a convex articular surface is parallel with the longitudinal axis of the bone.ivot joints allow for rotation, protraction, retraction,twist, flexion, extension, adduction and abduction, which can be external (for example when rotating an arm outward), or internal (as in rotating an arm inward). When rotating the forearm, these movements are typically called pronation and supination.
