plantar

adj. of or pertaining to the sole of the foot

In sciences dealing with the anatomy of animals, precise anatomical terms of location are necessary for a variety of reasons. Non-scientists often wonder why zoological and human anatomists use complex terminology to describe locations on a body, when common terms like "up", "down", "top" and "bottom" could be used instead.
