The cardiac neural crest complex is a form of neural crest

Neural crest

Neural crest cells are a transient, multipotent, migratory cell population unique to vertebrates that gives rise to a diverse cell lineage including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia....

.

The cardiac neural crest develops from the dorsal neural tube. It overlaps the vagal neural crest and migrates to populate the pharyngeal arches 3, 4 and 6 (producing structures in the head) and to the heart

Heart

The heart is a myogenic muscular organ found in all animals with a circulatory system , that is responsible for pumping blood throughout the blood vessels by repeated, rhythmic contractions...

, forming connective tissue that separates the great vessels of the heart.

• Into the pharyngeal arches and Truncus arteriosus (embryology)
  Truncus arteriosus (embryology)
  The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum. The truncus arteriosus gives rise to the ascending aorta and the pulmonary trunk. The caudal end of the bulbus cordis gives rise to the smooth parts of the left and right ventricles...

   and the smooth muscle
  Smooth muscle
  Smooth muscle is an involuntary non-striated muscle. It is divided into two sub-groups; the single-unit and multiunit smooth muscle. Within single-unit smooth muscle tissues, the autonomic nervous system innervates a single cell within a sheet or bundle and the action potential is propagated by...

  Great arteries is a term used to refer collectively to the primary arteries of the heart, which include:* Pulmonary artery: the vessel that carries oxygen-depleted blood from the right ventricle to the lungs....

NOTCH2

Neurogenic locus notch homolog protein 2 also known as notch 2 is a protein that in humans is encoded by the NOTCH2 gene.NOTCH2 is associated with Alagille syndrome and Hajdu–Cheney syndrome.- Function :Notch 2 a member of the notch family...
