Which section divides the body into anterior and posterior regions?

The correct choice is the frontal section, also known as the coronal section. This section divides the body into anterior (front) and posterior (back) regions. By slicing the body along the frontal plane, one can visualize the structures located at the front and back of the body, making it easier to assess and examine various anatomical features and orientations.

Understanding this division is fundamental in anatomy, particularly for clinical assessments and imaging techniques, where distinguishing front from back is essential for identifying the location of organs and structures.

The sagittal section cuts the body into left and right portions, whereas the transverse section divides it into superior (upper) and inferior (lower) parts. The dorsal section typically refers to parts of the body related to the back or posterior aspect but is not a term specifically used to describe a plane of sectioning.
