Anatomical Terms of Motion

Circumduction

• Circular Movement of a limb.

• What other joints circumduct?

Rotation

• Movement of a bone around its own long axis

• What other parts of your body rotate?

Supination/Pronation

• Supination: Movement of the body part so that it is face up or forward.

• Pronation: Movement of the body part so that it faces down or back.

• Can you supinate or

pronate any other part of your body?

Dorsi-Flexion

• Bending the foot at the ankle so that the toes move up toward the shin (toe raise).

• Dorsi-flexion only occurs in the foot.

Plantar Flexion

• Movement of the toes and foot away from the shin bone in the sagittal plane.

• Plantar flexion only occurs in the foot

Protraction

• An anterior movement • E.g. Pushing your

shoulders forward.

Retraction

• A posterior movement

• E.g. Pulling your shoulder blades back and together.

• What other body parts can you protract and retract?

Inversion

• Turning in of the soles of the feet so they face each other.

Eversion

• Turning out the soles of the feet so they face away from each other.

• What other body parts can be inverted and everted?

Extension

• An increase in the angle between two bones

• *be ware of the difference between hip extension and knee extension

Flexion

• A decrease in angle between two bones

• What other body parts can you flex?

• *be ware of the difference between hip Flexion and knee flexion.

Hyperextension

• Continuing extension beyond normal anatomical position.

- What joints of the body would hyperextend and which joints would not?

Elevation/Depression

• Elevation: Upward movement of a body part (usually applies to shoulder)

• Depression: Downward movement of a body part (usually applies to shoulder)

Adduction

• Movement of a limb or body segment toward the midline of the body.

Abduction

• Movement of a limb or body segment away from the midline of the body.

• What other parts of your body can Adduct and abduct?
