Anatomical terms of location
Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans.While these terms are standardized within specific fields of biology, there are unavoidable, sometimes dramatic, differences between some disciplines. For example, differences in terminology remain a problem that, to some extent, still separates the terminology of human anatomy from that used in the study of various other zoological categories.
