It overlaps the vagal neural crest and migrates to contribute to the pharyngeal arches 3, 4 and 6 (producing structures in the head) and to the heart where it contributes to connective tissue (septa) that separates the vessels of the heart. Cardiac neural crest develops into melanocytes, cartilage, connective tissue and neurons of some pharyngeal arches. NF stage 15 NF stage 40
