Muscle/Joint Movement
| Question | Answer |
|---|---|
| abduction | moving a body part away from the midline |
| adduction | moving a body part toward the body |
| extension | increasing the angle between two bones and move farther apart (straightening the knee) |
| flexion | decreasing the angle between two bones and the parts come closer together (bending the knee) |
| rotation | moving a part around an axis (twisting the head from side to side) |
| dorsiflexion | movement at the ankle that brings the foot closer to the shin (rocking back on one's heels) |
| plantar flexion | movement at the ankle that brings the foot farther from the shin (walking or standing on one's toes) |
| hyperextension | the extension of the parts at a joint beyond the anatomical position (bending the head back beyond the upright position); beyond the normal range of motion, resulting in injury |
| circumduction | moving a part so that its end follows a circular path (moving the finger in a circular motion without moving the hand) |
| pronation | rotation of the forearm so the palm is downward or facing posteriorly (in anatomical position) |
| supination | rotation of the forearm so the palm is upward or facing anteriorly (in anatomical position) |
| eversion | turning the foot so the plantar surface faces laterally |
| inversion | turning the foot so the plantar surface faces medially |
| retraction | moving a part backward (pulling the head backward) |
| protraction | moving a part forward (thrusting the head forward) |
| elevation | raising a part (shrugging the shoulders) |
| depression | lowering a part (dropping the shoulders) |
