SureHire explains medial plane

Anatomical planes are conceptual flat surfaces that divide the body and its parts into sections for the purpose of allowing clear communication of anatomical locations. The medial plane bisects the body into left and right sides longitudinally. The division of the body from front to back is achieved by the coronal plane. It is important to note that while the sagittal plane also divides the body longitudinally it does not create two equal parts.

It is the midsagittal, or medial, plane that forms the midline divider, and all other parallel planes are called sagittal (parasagittal) planes. The medial plane forms the central vertical line that divides the abdomen into quadrants.

Divisions such as this allow an ergonomist to be specific in planning for which specific muscle groups are affected by certain job duties. These divisions also assist health care professionals in diagnosing the origin of an injury.
