What is the term for a plane that divides the body into equal left and right halves?

The term for a plane that divides the body into equal left and right halves is the midsagittal plane. This anatomical plane runs vertically down the midline of the body, ensuring that both sides are mirror images of one another. It is an important reference in anatomy and medical imaging for understanding the bilateral symmetry of the body and organizing the spatial orientation of various structures.

In contrast, the transverse plane divides the body into superior (upper) and inferior (lower) parts, while the frontal plane separates the body into anterior (front) and posterior (back) sections. The coronal plane is actually synonymous with the frontal plane but often used more specifically in certain contexts to reference sections in relation to the front and back areas. Understanding the definition and function of the midsagittal plane is critical in fields like anatomy, surgery, and radiology, where precise localization of body structures is necessary.
