What is the term for the imaginary line dividing the body into equal left and right halves?

The term for the imaginary line dividing the body into equal left and right halves is "mid-sagittal." The mid-sagittal plane runs vertically through the center of the body, creating two symmetrical halves that mirror each other. This anatomical reference is crucial in various fields, including medicine and massage therapy, as it helps professionals understand and describe locations and movements of body structures.

In contrast, the coronal line, also known as the frontal plane, divides the body into anterior (front) and posterior (back) sections. The transverse line, or transverse plane, cuts the body into upper (superior) and lower (inferior) parts. The parasagittal plane, on the other hand, is parallel to the mid-sagittal plane but does not necessarily divide the body into equal halves; instead, it creates unequal left and right sections. Understanding these terms is essential for effective communication about body mechanics and therapeutic practices.
