Anatomical Terms and Planes of Section
Terms for Direction and Orientation Planes of Section Direction and Orientation - quadrupeds and bipeds   Anatomical terms of orientation in humans may be particularly confusing because similar terms are used differently in quadrupeds and bipeds.  This page may help you deal with the confusion.
