What plane divides the foot into plantar and dorsal sections?

The transverse plane is the correct choice because it divides the body into superior (upper) and inferior (lower) parts. When applied to the foot, this plane separates it into the plantar section (the sole or bottom of the foot) and the dorsal section (the top). This anatomical distinction is essential for understanding foot structure and function, particularly in the context of fitting therapeutic footwear, as it relates to weight distribution and pressure points when standing or walking.

In contrast, the sagittal plane divides the body into left and right sections, which wouldn't effectively differentiate between the top and bottom of the foot. The frontal plane, on the other hand, separates the body into anterior (front) and posterior (back) sections, which also does not provide the necessary division of the foot into plantar and dorsal. The term "coronal" refers to the same plane as frontal but is not typically used in the context of foot anatomy.
