Which plane is perpendicular to the sagittal and transverse planes?

The plane that is perpendicular to both the sagittal and transverse planes is known as the coronal plane. The coronal plane divides the body into anterior (front) and posterior (back) sections.

Understanding the anatomical planes is crucial for describing locations and movements within the body. The sagittal plane runs vertically, dividing the body into left and right portions, while the transverse plane divides it into upper (superior) and lower (inferior) sections. Since the coronal plane crosses the midline vertically and runs perpendicular to both the sagittal and transverse planes, it properly describes the division of the body in a way that complements these other planes.

The dorsal plane is primarily used in veterinary medicine to refer to the upper side of an animal but does not serve as a fundamental anatomical plane in the same way the coronal, sagittal, and transverse planes do. So while it does play a role in anatomical discussions, it does not fulfill the requirement of being perpendicular to both sagittal and transverse.

In summary, the coronal plane is the correct choice as it correctly intersects with the sagittal and transverse planes, effectively illustrating how the body can be divided or sections can be described in anatomical terms.
