neural crest


Also found in: Dictionary, Thesaurus, Legal, Financial, Encyclopedia, Wikipedia.

neu·ral crest

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.

neural crest

n.
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 crest

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

"We hope our findings can provide a new window into the diversity of neural crest cells and help explain both the normal development of cells that give rise to craniofacial, heart and sensory tissues but also some of the pathologic 'detours' along the way that lead to abnormalities of cell differentiation," said study co-senior author Igor Adameyko, a senior researcher at the Karolinska Institutet and the Medical University of Vienna.
