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 (neural, skin, heart, endocrine, GIT) will have a contribution fron the neural crest cells. General neural development is also covered in another section of these notes (Neural).

Beside the spinal cord neural crest cells form the sensory ganglia (dorsal root ganglia). In the head region neural crest cells migrate into the pharyngeal arches (as shown in movie below) and form many different structures.
