Neural Crest Development
Introduction
The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube. These cells migrate to many different locations and differentiate into many cell types within the embryo. This means that many different systems ([neuron.htm neural], [skin.htm skin], [skin10.htm teeth], [head.htm head], [face.htm face], [heart.htm heart], [endocrine9.htm adrenal glands], [git.htm gastrointestinal tract]) will also have a contribution fron the neural crest cells.
In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs.
In the head region, neural crest cells migrate into the pharyngeal arches (as shown in movie below) forming ectomesenchyme contributing tissues which in the body region are typically derived from mesoderm (cartilage, bone, and connective tissue).
General neural development is also covered in [neuron.htm Neural Notes].
