Anatomical planes are imaginary lines that divide the body to describe locations and directions of body parts. They’re essential for medical imaging, surgery, and anatomical studies. Here are the main anatomical planes:


1. Sagittal Plane

  • Divides the body into: Left and right sections
  • Types:
    • Midsagittal (median): Divides the body exactly in the middle into equal left and right halves.
    • Parasagittal: Any plane parallel to the midsagittal that divides the body into unequal left and right portions.

2. Frontal Plane (Coronal Plane)

  • Divides the body into: Anterior (front) and posterior (back) sections
  • Used for: Viewing or referencing structures from the front or back.

3. Transverse Plane (Horizontal or Axial Plane)

  • Divides the body into: Superior (upper) and inferior (lower) sections
  • Used in: CT scans and MRI images, as it shows cross-sectional views of the body.

4. Oblique Plane

  • Divides the body at: An angle (any plane not parallel to the sagittal, frontal, or transverse planes)
  • Used for: More complex or detailed imaging and anatomical studies.

Why They Matter

  • These planes help clinicians and anatomists:
    • Communicate clearly about the location of injuries, organs, or procedures.
    • Interpret medical imaging.
    • Plan surgeries or anatomical dissections.
