Nervous tissue originates from the ectoderm, one of the three primary germ layers formed during embryonic development. Specifically, it develops from the neural plate, which folds to form the neural tube, giving rise to the central nervous system (brain and spinal cord), while neural crest cells contribute to the peripheral nervous system. This differentiation is crucial for the formation of neurons and glial cells, which are essential for transmitting signals and supporting neural function.
