The concept of Cardinal Planes, which divide the body into equal halves in three different directions, is used to define how the body moves through space. It also provides the basis for movement terminology such as flexion and extension.
Sagittal, Frontal or Coronal and Transverse planes exhibited in this one quarter life size fully three dimensional model in the anatomical position. Original concept by Jennifer Bridges, Ph.D., Professor & Kinesiology Dept. chair, Saginaw State University.
