Anatomical terms of motion Anatomical terms of motion 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. In general, motion is classified according to the anatomical plane it occurs in. "Flexion" and "extension" are examples
Anatomical terminology or absence of the palmaris longus tendon. Anatomical variation is unlike congenital anomalies, which are considered a disorder. Joints, especially synovial joints allow the body a tremendous range of movements. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation. The type of movement that can be produced at a synovial joint is determined by its structural type. Movement types are generally paired, with one being the opposite of the other. Body movements are always described in relation to the anatomical position of
