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.

Week 6-7 (GA 8-9)

Movie shows a quick animation of the ventral views of the human embryo face, between Carnegie stage 16 to stage 18 (Week 6 to Week 7). Animation based on Kyoto embryos. Note the initial prominence of the pharyngeal arches and nasal region. Then the development of the midline frontonasal region and the relative shifting of the nasal region from lateral to anterior location on to the developing face.

Week 5-8 (GA 7-10)

Movie shows a quick animation of the lateral view of the human embryo head, between Carnegie stage 15 to stage 22 (Week 5 to Week 8). Note that these stage images are not to scale. Links: MP4 version | Face Development Movie | Lecture - Head Development | Movies

Secondary Palate Development

<mediaplayer width='200' height='220' image="http://embryology.med.unsw.edu.au/embryology/images/4/4f/Palate_001_icon.jpg">File:Palate_001.mp4</mediaplayer>

Animation shows an inferior view of the developmental sequence of secondary palate formation. Animation shows the left and right maxillary processes of the first pharyngeal arch. Primary palate formation is the fusion of these maxillary processes with the frontonasal prominence (FNP) in the midline. Frontonasal prominence (FNP) contributing midline component of the upper jaw as well as the the philtrum of the upper lip. Secondary palate formation is the growth of the palatal shelves towards the midline.

Animation shows an anterior view of the developmental sequence of secondary palate formation. Animation shows the left and right maxillary processes of the first pharyngeal arch. Primary palate formation is the fusion of these maxillary processes with the frontonasal prominence (FNP) in the midline. Frontonasal prominence (FNP) contributing midline component of the upper jaw as well as the the philtrum of the upper lip. Secondary palate formation is the growth of the palatal shelves towards the midline.
