Development of the Face This animation shows a ventral view of development of the human face from approximately week 5 through to neonate. The separate embryonic components that contribute to the face have been colour coded. Frontonasal Prominence central portion (white) Frontonasal Prominence - Lateral nasal (purple) Frontonasal Prominence - Medial nasal (green) Pharyngeal Arch 1 - Maxillary prominence (yellow) Pharyngeal Arch 1 - Mandibular prominence (orange) Stomodeum (black) The stomodeum is the primordial mouth region and a surface central depression lying between the forebrain bulge and the heart bulge. At the floor of the stomodeum indentation is the buccopharyngeal membrane (oral membrane). Note the complex origin of the maxillary region (upper jaw) requiring the fusion of several embryonic elements, abnormalities of this process lead to cleft lip and cleft palate. See also the movie (Quicktime | Flash) showing a similar view of human embryo faces between Carnegie stage 16 to 18.

Aim: To introduce the developmental embryology of the head and face, and their associated abnormalities. Specific Objectives: To understand the formation and contribution of the pharyngeal arches to face and neck development. To know the main structures derived from components of the pharyngeal arches (groove, pouch and arch connective tissue). To briefly understand some abnormalities associated with head development.
