|
|
Rotation
|
Turning movement
Movement of a body part around an axis Ex: twisting the head from side to side |
|
|
Depression/Elevation
|
Raising and lowering a body part
Depression - Lowering a body part such as drooping the shoulders Elevation - Raising a body part, such as shrugging the shoulders |
|
|
Protraction/Retraction
|
Moving a body part backward and forward
Protraction - moving a body part forward such as thrusting the chin forward Retraction - moving a body part backward such as pulling in the chin |

|
|
Flexion/Extension
|
Flexion
Movement to reduce the angle between the 2 bones Extension - Movement to increase the angle between the 2 bones |
|
|
Abduction/Adduction
|
Abduction - moves a body part awayfrom the midline
Adduction - moves a body part toward the midline |
|
|
Circumduction
|
movement of an arm or leg in a circular motion to outline a cone in space
|
|
|
Levers
|
Levers increase the efficiency of movement
Each bone is a lever, and each joint is a fulcrum |
|
|
First class Levers
|
Seesaw
Fulcrum lies between the applied force and the load EFR or RFE Ex: extension of the neck |
|
|
Second Class Levers
|
Wheelbarrow
Load (weight)lies between the applied force (upward lift)and the fulcrum Force is farther from the fulcrum than than the load, so a small force can move a large weight FRE or ERF Ex:Ankle extension (plantar flexion) by the calf muscles) |
|
|
Third Class Levers
|
Most common in the body
Force is applied between the load and the fulcrum FER Ex: bending the arm |
