Anatomical terminology [edit on Wikidata]

The transverse plane (also known as the horizontal plane, axial plane and transaxial plane) is an anatomical plane that divides the body into superior and inferior sections. It is perpendicular to the coronal and sagittal planes.

List of clinically relevant anatomical planes

• Transverse
  thoracic plane
• Xiphosternal plane (or xiphosternal junction)
• Transpyloric plane
• Subcostal plane
• Umbilical plane
  (or transumbilical plane)
• Supracristal plane
• Intertubercular plane (or transtubercular plane)
• Interspinous plane

Clinically relevant anatomical planes with associated structures

• 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 junction
  )
  • Anterior, inferior limit of thoracic cavity;
  • Marks the:
    • Superior surface of the liver;
    • Respiratory diaphragm;
    • Inferior border of the heart;
• 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
    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
  • Located at the level of L4;
  • Marks bifurcation of aorta;
  • Most superior aspect of iliac crest;
• 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.
