Midsagittal Plane
A plane that passes vertically through the midline and divides the body into equal right and left halves.
Parasagittal Plane
A plane that passes vertically through the body dividing it into unequal right and left sections.
Frontal or Coronal Plane

A plane that passes horizontally through the body and divides the body into superior and inferior sections.
Transverse sections or Cross-sections
The superior and inferior sections produced by a Transverse plane passing horizontally through a body or organ.
Oblique planes
A plane that passes through the body at an angle forming oblique sections.
Longitudinal Sections
Sections that are produced by a plane running along the long axis of a long narrow structure. ex: blood vessels, intestines, or long bones.
Cross-Sections
Sections that are produced by a plane running 'perpendicular' to the long axis.
Axial Sections
Transverse sections observed with computed tomography (CT) scans or magnetic resonance imaging (MRI).
