| Question | Answer |
|---|---|

| Extention | increases the angle between bones |
| Abduction | moves a part away from the median plane of the body, as in moving the leg straight out to the side or fingers away from the midline of the hand |
| Adduction | moves a part toward the median plan |
| Internal rotation | rotation toward the center of the body; pivoting a bone towards the midline on it's own axis |
| External rotation | rotation away from the center of the body; pivoting a bone away from the midline on it's own axis |
| Elevation | moves a part up, as in closing the mouth |
| Depression | lowers a part, moving it in the opposite direction from elevation |
| Pronation | turns the palm of the hand down |
| Supination | turns the hand palm side up |
| Dorsiflexion | decreasing the angle between the top of the foot and the front of the leg |
| Plantar flexion | increases the angle between the top of the foot and the front of the leg |

| Inversion | turns the sole of the foot inward |
| Protrusion | extended forward or laterally |
| Retrusion | being pulled back |
