Glossary
In this section, you will find a description (not exhaustive) of the main terms used in diagnosis. They make it possible to describe precisely a part of the sea urchin, its shape, or the relative position of a particular structure. This glossary includes figures where the terminology is reported, since the adage in France says that "a little drawing is better than a long speech".
