Question

the following description describes the neural ______________. at 24 days after conception, the precursor of the pns is visible in the developing embryo, and is just dorsal to the developing spinal cord. crest stem plate tube groove

Explanation:

The neural crest is a structure in the developing embryo. It gives rise to many components of the peripheral nervous system (PNS). At 24 days after conception, it is located dorsal to the developing spinal cord. The neural stem is related to neural stem cells which are more about cell - lineage. The neural plate is an early structure that folds to form the neural tube. The neural tube forms the central nervous system (CNS, like the spinal cord and brain). The neural groove is an intermediate stage in neural tube formation.

Answer:

crest
