Vertebrate faces come in many guises but they all develop from seven segmented regions (the pharyngeal arches), among which are intercalated outpockets of endodermal tissue, called 'pouches'.

Craniofacial abnormalities often arise during formation of the pharyngeal arches destined to give rise to many craniofacial structures. The complexity of arch derivatives is reflected in their ...
