Which body plane divides the body into left and right parts?

The sagittal plane is the correct answer because it specifically divides the body into left and right sections. This plane runs vertically from the front to the back of the body and is parallel to the midline, which means it separates the body into two symmetrical halves if it divides perfectly down the center. The significance of the sagittal plane lies in its application in various medical, anatomical, and physiological contexts, such as understanding movement patterns and assessing injuries.

In contrast, the frontal plane, also known as the coronal plane, divides the body into anterior (front) and posterior (back) parts. The transverse plane, or horizontal plane, cuts the body into superior (upper) and inferior (lower) sections, while the oblique plane refers to any diagonal cut that does not conform to the standard vertical or horizontal planes. Understanding these different planes is essential for accurate anatomical references, assessments, and communication in physical therapy and related fields.
