Motion, the process of movement, is described using specific
anatomical terms. Motion includes movement of
organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the
anatomical position of the joints.
Anatomists use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing the uniqueness of the movements such as those of the hands, feet, and eyes.
