Which plane divides the body into anterior and posterior portions?

The correct answer is the coronal plane because it is defined as a vertical plane that divides the body into anterior (front) and posterior (back) sections. Understanding body planes is crucial in anatomy, as they provide a way to describe locations and directions in the body. The coronal plane runs perpendicular to the sagittal and transverse planes, making it specifically suited for separating the body into front and back halves.

In contrast, the sagittal plane divides the body into left and right portions, which is not what the question is asking. The transverse plane, also known as the horizontal plane, divides the body into superior (upper) and inferior (lower) sections, which again does not fulfill the requirement of dividing into anterior and posterior portions. Thus, the coronal plane is the most appropriate choice for this question.
