Difference between the Coronal Plane and Sagittal Plane: The Coronal Plane bisects the body into anterior (front) and posterior (back) sections. It is perpendicular to both the sagittal and transverse planes. This plane is crucial for understanding side-to-side movements such as abduction and adduction. On the other hand, the Sagittal Plane bisects the body into left and right halves, leading to the comprehension of forward and backward movements like flexion and extension.
Difference between the Coronal Plane and the Sagittal Plane
The Coronal Plane divides the body into front and back sections. On the other hand, the Sagittal Plane divides it into left and right halves, essential for understanding lateral and forward-backwards movements, respectively. The table below provides the differences between the Coronal Plane and the Sagittal Plane.

What is a Coronal Plane?
The Coronal Plane is a vertical plane that divides the body into front (anterior) and back (posterior) sections. It is perpendicular to both the sagittal and transverse planes, providing a framework for understanding side-to-side movements such as abduction and adduction.
Key Features of Coronal Plane
- Orientation: The Coronal Plane divides the body into anterior (front) and posterior (back) portions. It is perpendicular to the Sagittal Plane, which divides the body into left and right portions, and to the transverse plane, which again divides the body into upper and lower portions.
- Movement: Movements such as abduction and adduction occur within the Coronal Plane. Abduction involves moving a body part away from the midline of the body, while adduction involves moving it towards the midline.
- Anatomical Imaging: In medical imaging, such as MRI or CT scans, the Coronal Plane is often used to capture images of the body from a front-to-back perspective. This allows for visualization of structures such as organs, muscles, and bones about their anterior and posterior positions.
- Clinical Applications: Understanding the Coronal Plane is crucial in various clinical contexts. For example, when diagnosing fractures or injuries, physicians may refer to the orientation of bones or tissues relative to the Coronal Plane to determine the extent and location of damage.
What is a Sagittal Plane?
The Sagittal Plane is another anatomical term used to describe a plane that divides the body into left and right portions. It is named after the sagittal suture of the skull, which lies in this plane in an upright human.
Features of Sagittal Plane
- Orientation: The Sagittal Plane is perpendicular to both the Coronal (frontal) plane, which divides the body into anterior and posterior portions, and the transverse plane, which divides the body into upper and lower portions.
- Midline: The Sagittal Plane passes through the midline of the body, dividing it into symmetrical left and right halves.
- Movement: Movements such as flexion and extension occur within the Sagittal Plane. Flexion involves decreasing the angle between body parts, typically in a forward direction, while extension involves increasing the angle, usually in a backward direction.
- Anatomical Imaging: In medical imaging, the Sagittal Plane is often used to capture images of the body from a side-to-side perspective. This allows for visualization of structures such as the brain, spinal cord, and joints about their left and right positions.

Similarities between the Coronal Plane and Sagittal Plane
- Divisive Nature: Both planes divide the body into distinct sections. The Coronal Plane divides the body into anterior (front) and posterior (back) portions, while the Sagittal Plane divides it into left and right portions.
- Perpendicularity: Both planes are perpendicular to each other. The Coronal Plane is perpendicular to the Sagittal Plane, and vice versa. This perpendicular relationship allows for comprehensive anatomical description and understanding of three-dimensional structures within the body.
- Midline Reference: Both planes pass through the midline of the body. In the Coronal Plane, the midline is the vertical plane passing through the centre of the body from front to back, while in the Sagittal Plane, it divides the body into symmetrical left and right halves.
In summary, while both planes play important roles in anatomical descriptions and movements, the Coronal Plane divides the body into front and back portions, whereas the Sagittal Plane divides it into left and right portions.
