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 (neural, skin, teeth, head, face, heart, adrenal glands, 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 Neural Notes.

Neural Crest Migration
Movie Source: Original Neural Crest movies kindly provided by Paul Kulesa.
The following cranial and trunk data is based upon 185 serially sectioned staged (Carnegie) human embryos.
Cranial Neural Crest
- stage 9 - an indication of mesencephalic neural crest
- stage 10 - trigeminal, facial, and postotic components
- stage 11 - crest-free zones are soon observable in rhombomere 1, 3, and 5
- stage 12 - rhombomeres 6 and 7 neural crest migrate to pharyngeal arch 3 and then rostrad to the truncus arteriosus
- stage 13 - nasal crest and the terminalis-vomeronasal complex are last of the cranial crest to appear
stages 9-14 - otic vesicle primordium descends
Trunk Neural Crest
Spinal ganglia increase in number over time and are in phase with the somites, though not their centre. There are 3 migratory pathways: ventrolateral between dermatomyotome and sclerotome, ventromedial between neural tube and sclerotomes, and lateral between surface ectoderm and dermatomyotome.
- stage 13 - about 19 present
- stage 14 - about 33 present
- stage 15-23 - 30–35 ganglia
