what are cartilaginous joints
slightly moving
e.g. vertebrae
what does your hinge joint do
allows flexion and extension only
e.g. elbow, knee, wrist, ankle
what do your ball and socket joints do
allows movement in all directions ( flexion, extension, circumduction, medial and lateral rotation, adduction, abduction)
e.g. shoulder and hip
what do your condyloid joints do
movement is limited in all directions except rotation
e.g. carpals, metacarpals, tarsals, metatarsals
what do your pivot joints do
rotation only
e.g. atlas, axis in neck
what do your gliding joints do
movement is limited except rotation
e.g. carpals and tarsals
what do your saddle joints do
