1

Flexion

Decreases angle of joint in sagittal plane

2

Extension

Increases angle of joint in sagittal plane

3

Hyperextension

Goes beyond anatomical position in sagittal plane

4

Abduction

Moves bone away from midline in frontal plane

5

Adduction

Moves bone toward midline in frontal plane

6

Rotation

Bone spins around its own axis

7

Circumduction

Bone describes a cone, in space (point of cone is on joint)

8

Supination

Movement of radius around ulna so palm faces forward or up

9

Pronation

Movement of radius around ulna so palm faces backward or down

10

Inversion

The sole of the foot turns medially, at ankle

11

Eversion

The sole of the foot turn laterally at ankle

12

Elevation

The jaw or shoulder moves upward (as in closing mouth, shrugging up)

13

Depresssion

The mandible or shoulder moves downward (as in dropping jaw)

14

Radial Deviation

Wrist swings in frontal plane towards radius

15

Ulnar Deviation

Wrist swings in frontal plane toward ulna

16

Protraction

Jaw or shoulder moves forward in sagittal plane

17

Retraction

Jaw or shoulder moves backward in sagittal plane

18

Dorsi-flexion

Movement of the ankle where the toes move superiorly

19

Plantar-flexion

Movement of the ankle where the toes move inferiorly

20

Opposition

Thumb can touch each fingertip

21

Reposition

Thumb and fingertips go back to anatomical position
