frontal plane[¦frənt·əl ¦plān]
a term used in animal and human anatomy to designate an imaginary plane that runs through the body parallel to the surface of the frons (forehead) and perpendicular to the sagittal and transverse planes. In animals the frontal plane passes horizontally along the body (when there is a horizontally extended head); in man it passes vertically, for example, through both hip joints. The frontal plane divides the body into front and back parts.
