An embryo at an early stage of development in which neurulation begins.

neurula

[noo͡r′ələ] pl. neurulas, neurulae
Etymology: Gk, neuron, nerve
an early embryo during the period of neurulation when the nervous system tissue begins to differentiate. The embryo at this level of growth represents a third stage in embryonic development, after the morula and blastocyst stages in humans and higher animals and the blastula and gastrula stages in lower animals. In humans the neurula stage occurs from about 19 to 26 days after fertilization.

neu·ru·la

, pl. neurulae (nūr'yū-lă, -lē)
Stage in embryonic development during which the neural plate forms and closes to form the neural tube.
[neur- + L. -ulus, small one]

neurula

the stage of a vertebrate embryo when gastrulation is largely finished and a neural plate is forming, ending with the formation of the neural tube.

neurula
