Multiple Choice Questions in Neuroscience Nursing:Embryonic Development
Introduction-Neuroembryonic Development
The nervous system development can be recognized as early as 3 weeks in a human embryo.
Initially there is a longitudinal invagination on the dorsal portion of the ectodermal layer, which develops into a neural groove and a neural tube.
Although it is one of the earliest system to start the development, neuroembryonic development is completed after birth.
