What plane divides the body into equal right and left halves?

The plane that divides the body into equal right and left halves is called the mid-sagittal plane or median plane. This anatomical plane runs vertically through the midline of the body, effectively creating two symmetrical halves: one side representing the right half and the other representing the left half.

In addition, there are other sagittal planes, which are parallel to the mid-sagittal plane but do not divide the body equally. These are referred to as parasagittal planes. Understanding these planes is crucial in anatomy and medical imaging, as they help in describing the location of structures and guiding interventions or assessments.

Overall, the mid-sagittal plane is a fundamental concept in anatomy for discussing body symmetry and orientation.
