Dorsiflexion refers to the flexion of the ankle, so that the foot points more superiorly.
What is plantar flexion?
Plantar flexion refers to the extension of the ankle, so that the foot points inferiorly.
What is medial rotation?
Medial rotation is a rotational movement towards the midline, also called internal rotation.
What is lateral rotation?
Lateral rotation is a rotating movement away from the midline.
What is inversion?
Inversion involves the movement of the sole of the foot towards the median plane.
What is eversion?
Eversion involves the movement of the sole of the foot away from the median plane.
What is opposition?
Opposition brings the thumb in contact with a finger.
What is reposition?
Reposition is a movement that moves the thumb and the little finger away from each other.
What is circumduction?
Circumduction is a conical movement of a limb extending from the joint at which the movement is controlled.

What is retraction?

What is excursion?
