What is the term for an imaginary line that divides the body into a right and left side?

The term for an imaginary line that divides the body into a right and left side is the midsagittal plane. This plane runs vertically through the body and bisects it equally, resulting in two mirror-image halves. It is specifically oriented along the midline of the body, creating symmetrical sections.

The coronal plane, on the other hand, divides the body into anterior (front) and posterior (back) sections. The transverse plane separates the body into superior (upper) and inferior (lower) parts, and the frontal plane serves a similar function to the coronal plane but is often used in a more general sense to signify any vertical plane dividing the body. Understanding these different anatomical planes is essential in fields like health sciences, as they provide a framework for describing the location of body structures and facilitate communication among healthcare professionals.
