Final answer:
The plane that divides the body into anterior and posterior sections is called the frontal plane or coronal plane in biology.
Step-by-step explanation:
The plane that divides the body into anterior and posterior sections is called the frontal plane (also known as the coronal plane). This plane is perpendicular to the sagittal plane, which divides the body into right and left sections. The frontal plane is commonly used in anatomical studies to examine structures from the front and back.
For example, when you look at a human body in an anterior view (front), the frontal plane would divide the body into the front and back portions. Similarly, in a posterior view (back), the frontal plane would divide the body into the back and front portions.
Understanding body planes and sections is fundamental in the study of anatomy and provides a basis for comprehending how different parts of the body function and relate to each other.
