| gliding joints | also known as plane joint and allows for gliding movements. ex wrist and ankle |

| circumduction | moving limb in a circle. ex. arms circles |
| elevation and depression | lifting then lowering a body part. ex. shrugging your shoulders |
| protraction and retraction | sticking jaw out to make an under bite and back in |
| dorsiflexion and plantar flexion | lifting foot up and down at the ankle |
