Definitions related to neural crest:
-
A cell region originating at the margins of the dorsal part of the neural tube during the early stages of embryonic development that migrates to multiple locations within the embryo, and are multipotent, giving rise to a vast number of differentiated cell and tissue types.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Strip of specialized ectoderm flanking each side of the embryonal neural plate, which after the closure of the neural tube, forms a column of isolated cells along the dorsal aspect of the neural tube; most of the cranial and all of the spinal sensory ganglion cells arise by differentiation of neural crest cells.CRISP ThesaurusNational Institutes of Health, 2006
-
The two longitudinal ridges along the PRIMITIVE STREAK appearing near the end of GASTRULATION during development of nervous system (NEURULATION). The ridges are formed by folding of NEURAL PLATE. Between the ridges is a neural groove which deepens as the fold become elevated. When the folds meet at midline, the groove becomes a closed tube, the NEURAL TUBE.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Neural crest, group of embryonic cells that are pinched off during the formation of the neural tube (the precursor of the spinal cord) but that do not remain as a part of the central nervous system. The cells of the neural crest migrate to numerous locations in the body and contribute to the...Encyclopedia Britannica, Inc., 2020
