Synovial Joints
Types of Movements that occur @ Synovial Joints
Question | Answer |
---|---|
Flexion | A movement that decreases the angle of the joint and reduces the distance between the two bones (Bending). |
Extension | Movement that increases the angle of the joint and the distance between the bones (straightening). |
Hyperextension | Extension greater than 180 degrees. |
Rotation | Movement of a bone around its longitudinal axis. (turning head from side to side) |
Abduction | Movement of limb AWAY from midline of the body. |
Adduction | Movement of a limb toward the midline of the body ("adding") |
Circumduction | Combination of flexion, extension, abduction, and adduction - proximal end of limb remains stationary as the distal end moves in a circle. |
Pronation | Movement of the palm of the hand from the anterior position to the posterior position. |
Eversion | Refers to foot: (Big toe to floor) - lateral turning of the sole of the foot. |
Inversion | Refers to foot: (Pinky toe to floor) - medial turning of the sole of the foot. |
Dorsiflexion | Refers to the foot: movement of the ankle in a dorsal direction (lifting toes up; heel is down) |
Plantar flexion | Refers to the foot: Movement of the ankle in which the foot is flexed down (pointing toes like a ballerina). |
