syntharthrosis
examples include sutures, gomphoses, synchondroses
synarthrosis
parietal bones of the skull, hard palate
sutures
teeth, styloid process in temporal bone

gliding
aka sella, thumb
saddle
aka condyloid, radiocarpal, atlanto-occipital
ellipsoid
aka spheroid, hip and shoulder (greatest ROM)
ball and socket
examples of diarthrosis
hinge, pivot, gliding, saddle, ellipsoid, ball and socket
