Movement
| Question | Answer |
|---|---|
| we describe movement of the body parts in terms of.... | anatomical position |
| flexion | reducing angle between bones (thin of the curled up guy) |
| extension | increasing angle between bones (think of the arched out guy) |
| hyperextension | further extension of joint past anatomical position |
| lateral flexion | flexing to side |
| medial flexion | flexing back up to the start |
| dorsiflexion | flexing the dorsum up, toes point up |
| plantar flexion | flexing sole of foot down/ toes point downward |
| abduction | moving away from midline (in the frontal plane) think: "AB"solutely I want to make a snow angel!" |
| example of flexion | flexing bicep |
| example of extension | returning arm to starting point |
| example of hyperextension | pushing head backward to look up |
| elevation | structure moves superiorly (moving in frontal plane) |
| depression | structure moves inferiorly (moving in the frontal plane) |
| example of elevation | shrugging shoulders |
| example of depression | bringing shoulders down after shrug |
| protraction | structure moves anteriorly (moving on the transverse plane) |
| retraction | structure moves posteriorly (moving on the transverse plane) |
| example of protraction? | push jaw foward |
| example of retraction? | bring jaw back |
| lateral excursion | moving mandible side to side |
| medial excursion | bringing mandible back to midline |
| circumduction | proximal end of the appendage remains relatively stationary, while distal end makes circular motion |
| rotation | turning of a bone around its long axis |
| lateral rotation | turn away from midline |
| medial rotation | turn toward midline |
| examples of rotation? | rotate head, or humerus. |
| supination | turns palm to face anteriorly/upward (think holding cup of SOUP) |
| pronation | turns palm to face posteriorly/downward (think you are "prone" to be in most comfy position) |
| opposition | tip of thumb goes to tips of other fingers (think "opposable" thumb) |
| reposition | return thumb to normal position |
| inversion | sole of foot turns medially |
| eversion | sole of foot turns laterally |
