sentences:  The renaming of the hippocampus as hippocampus major, and the calcar avis as hippocampus minor, has been attributed to Félix Vicq-d'Azyr systematising nomenclature of parts of the brain in 1786.While "hippocampus minor" was used interchangeably with "calcar avis" for much of the 19th century, for a few years after 1861 the former name was subjected to publicity and ridicule when the hippocampus minor became the centre of a dispute over human evolution between Thomas Henry Huxley and Richard Owen, satirised as the Great Hippocampus Question.The term hippocampus minor fell from use in anatomy textbooks, and was officially removed in the Nomina Anatomica of 1895, but still featured in the "Encyclopædia Britannica" of 1926, and appeared in general dictionaries as late as 1957.
