Median Plane Cuts the body into Right and Left parts (down the

middle of the body) Sagittal section - separates right and left Midsagittal section– separates right and left down

the middle Frontal Plane

Cuts the body into anterior and posterior (front and back) sections (Coronal section)

Transverse Section Cuts along a horizontal plane into superior and
