Which plane divides the body into right and left parts?

The sagittal plane is the correct choice, as it specifically divides the body into right and left parts. This plane runs vertically from the front to the back of the body and allows for the examination of movements and organs on either side of the midline.

In anatomical terms, when referring to the sagittal plane, it often implies a midsagittal plane, which divides the body exactly into two equal halves. This division is essential in understanding anatomical structures, movement patterns, and various clinical assessments related to the body's symmetry.

The coronal plane, also known as the frontal plane, separates the body into anterior (front) and posterior (back) sections. The transverse plane, on the other hand, divides the body into superior (upper) and inferior (lower) parts. These other planes serve different purposes in anatomy and clinical assessments but do not specifically create a right and left division as the sagittal plane does.
