Transverse plane

The transverse plane or axial plane (also called the horizontal plane or transaxial plane) is an imaginary plane that divides the body into superior and inferior parts. It is perpendicular to the coronal plane and sagittal plane.

For the planes of a gear, see List of gear nomenclature.

List of clinically relevant anatomical planes

Clinically relevant anatomical planes with associated structures
Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of surface anatomy. The transpyloric plane is given near center.
  • The transverse thoracic plane
    • Plane through T4 & T5 vertebral junction and sternal angle of Louis.
    • Marks the:
      • Attachment of costal cartilage of rib 2 at the sternal angle;
      • Aortic arch (beginning and end);
      • Upper margin of SVC;
      • Thoracic duct crossing;
      • Tracheal bifurcation;
      • Pulmonary trunk bifurcation;
  • The xiphosternal plane (a.k.a. xiphosternal junction)
  • The transpyloric plane
    • Plane located halfway between the jugular notch and the upper border of the symphysis pubis;
    • Typically located at the lower border of L1;
    • Cuts through the pylorus and the tips of the ninth costal cartilages;
  • The subcostal plane
    • Transverse plane through the inferior border of costal margin;
    • Typically located at the superior border of L3, or transects L3;
  • The umbilical plane (or transumbilical plane)
    • Located at the level of L3/L4 vertebral junction or IV disc;
  • The supracristal plane
  • The intertubercular plane (a.k.a. Transtubercular plane)
    • Located at the level of L5;
    • Marks origin of IVC;
  • The interspinous plane
    • Transverse plane which transverses the anterior superior iliac spines.
    • Typically located at the level of S1.
