Neural crest

Definition

The neural crest is a group of cells that emerges from the edge of the neural tube, an embryonic precursor to the central nervous system, during early vertebrate development. These cells migrate to various parts of the embryo where they differentiate into diverse cell types including neurons, glial cells, and melanocytes.

Neural Tube: The precursor to the central nervous system formed from a folding layer of ectoderm during embryogenesis.

Neurons: Specialized cells that transmit nerve impulses; these are critical components of the nervous system and brain.

Glial Cells: Supportive cells in the nervous system that provide insulation, nutrients, and support for neuronal function; they also participate in signal transmission
