Movement system
The physiological components that function together to produce motion at a joint or multiple body segments. The components include the support and base; modulating nerves and muscles; cardiovascular and pulmonary reserves; and cognitive-affective elements. Specialists in physical medicine are trained to manage the components of the movement system.
-
Vermicular movement
The wormlike movements of peristalsis.
-
Triplanar movement
Movement occurring around an oblique axis in all three body planes.
-
Tooth movement
The change in position of a tooth or teeth in the dental arch. This may be due to abnormal pressure from the tongue, pathological changes in tooth-supporting structures, malocclusion, missing teeth, or a therapeutic orthodontic procedure. Thumb sucking, if prolonged, may cause malocclusion and, eventually, displacement of teeth.
-
Tipping movement
Movement of a tooth crown while the root apex remains essentially stationary, resulting in an inclination of the axis of the tooth in one direction.
-
Segmenting movement
Movement of the intestine in which annular constrictions occur, dividing the intestine into ovoid segments.
-
Saccadic movement
Jerky movements of the eyes as they move from one point of fixation to another.
-
Rotational movement
Movement around an axis, as in hinge movement of the temporomandibular joint or rotation of a tooth around its longitudinal axis in tooth movement or extraction.
-
Movement of restitution
Alteration in position that aligns the fetal head with the fetal spine.
-
Respiratory movement
Any movement resulting from the contraction of respiratory muscles or occurring passively as a result of elasticity of the thoracic wall or lungs.
