Amphiarthrosis
Definition
A type of semi-movable bony joint characterized by the presence of a structural fibrocartilaginous disc situated between the articular surfaces, bound by strong peripheral ligaments that limit movement to a simple sliding or minimal flexion. Classic examples in human anatomy are the joints between vertebral bodies (intervertebral discs) and the pubic symphysis.
