What plane divides the body or organ into front and back portions?

The plane that divides the body or an organ into front and back portions is known as the frontal plane. This anatomical plane runs vertically from one side of the body to the other and separates the anterior (front) and posterior (back) sections.

In the context of human anatomy, understanding this division is essential for visualizing and describing locations and movements of various body parts. For example, when performing assessments or procedures, medical professionals often reference the frontal plane to specify whether they are discussing issues that pertain to the front of the body, like the chest and face, versus the back, like the spine and posterior aspects.

The frontal plane is also critical in understanding topics such as movements that occur in this plane, which include actions like jumping jacks or lateral arm raises. This concept plays a significant role in physical education, sports science, and rehabilitation practices.
