Final answer:
Anatomists divide the body with three imaginary planes called sagittal, coronal, and transverse planes.
Step-by-step explanation:
Anatomists divide the body with three imaginary planes called sagittal, coronal, and transverse planes. The sagittal plane divides the body vertically into right and left sides. The coronal plane, also known as the frontal plane, divides the body into anterior (front) and posterior (rear) portions. The transverse plane divides the body horizontally into upper and lower portions.
