I. ROLE OF PREFIXION IN THE FORMATION OF ANATOMICAL AND HISTOLOGICAL TERMS

It is known that the body or organs of the body may be sectioned according to planes of reference. These include a midsagittal plane that runs vertically through a structure, dividing it into right and left halves; a sagittal plane that runs vertically through a structure, dividing it into right and left portions; a coronal (frontal) plane that runs vertically through a structure, dividing it into anterior (front) and posterior (back) portions; and a transverse (cross-sectional) plane that runs horizontally through a structure, dividing it into upper and lower portions.

In the anatomical terminology a great variety of terms with the spatial location meaning is used. The fundamental importance in this aspect have Latin and Greek prefixes as follows:
