Word History

Etymology

borrowed from New Latin (in a French context), "cluster of embryonic cells in marine gastropods that develop into the nervous system and eyes," from Greek neûron "sinew, tendon, nerve" + New Latin -ula (in gastrula gastrula) — more at nerve entry 1

Note: Term apparently introduced by the Swiss embryologist Hermann Fol (1845-92) in "Sur le dèveloppement des hétéropodes," Comptes rendus hebdomadaires des séances de l'Académie des Sciences, tome 81 (juillet-décembre 1875), pp. 472-74. In reference to vertebrate embryology the word was employed later by the German embryologist August Rauber (1841-1917) in Primitivstreifen und Neurula der Wirbelthieren, in normaler und pathologischer Beziehung (Leipzig, 1877).

First Known Use
