external and internal bodily motor acts (processes) consciously regulated by the subject on the basis of the need to achieve the goal as an image of the anticipated result. It involves a conscious orientation in relation to the goal both in terms of speech and imagination. They can be performed both by means of skeletal muscles, realizing the spatial positions of the body, and smooth muscles of internal organs (for example, blood vessels), realizing autonomic functions. Movements initially formed as involuntary can become voluntary due to the displacement of motor landmarks into the external plane (for example, when observing the changing tone of blood vessels on the scale of a measuring device) with the subsequent transfer of landmarks to the internal plane, in the form of specific motor, kinesthetic landmarks.
