neuroectodermal cells that originate in the dorsal aspect of the neural folds or neural tube. These cells leave the neural tube or folds and differentiate into various cell types including posterior-root ganglion cells; autonomic ganglion cells; the chromaffin cells of the suprarenal medulla; Schwann cells; sensory ganglia cells of cranial nerves V, IX, and X; part of the meninges; or integumentary pigment cells.

The part of the ectoderm in a vertebrate embryo that lies on either side of the neural tube and develops into the cranial, spinal, and autonomic ganglia.

neu·ral crest(nūr'ăl krest)
A band of neuroectodermal cells along either side of the line of closure of the embryonic neural groove; with the formation of the neural tube, these bands come to lie dorsolateral to the developing spinal cord and lateral to the brainstem, where they separate into clusters of cells that develop into, for example, spinal ganglion cells, autonomic ganglion cells, the chromaffin cells of the suprarenal medulla, Schwann cells, sensory ganglia of cranial nerves V, VII, VIII, IX, and X, part of the meninges, or integumentary pigment cells.

neural crestthe ridge of ectoderm occurring directly above the neural tube in the development of the vertebrate embryo; it gives rise to the PERIPHERAL nervous system.
