In medical language we find a large number of eponyms whose use pays tribute to scientists who described pathology, a sign, a technique, an anatomical or microscopic structure, etc. To pay tribute to those who with their research enriched Medicine and Morphological Sciences particularly and to contribute to the knowledge of the historical Embryology terminology we made an illustrated eponyms glossary for the medical / dental community and the students. To elaborate the glossary, the presence and significance of eponyms in General and Special Embryology books (1950-2018), serial publications, databases and virtual encyclopedias were investigated. Anatomical, Histological and Embryological Terminology Symposia recommend perpetuating eponyms and vernacular folk terms with historical interest only. To use a common scientific language and a single denomination that avoids confusion and optimizes communication and learning, priority should be given to the use of normative terminology.
