Introduction
This page will be updated and contain the final conference presentation.

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.
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 3
Gestational Age (GA week 5)
These images of the Stage 11 embryo show the breakdown of the buccopharyngeal membrane.
Week 4 to 5
Gestational Age (GA week 6 to 7)
Begins week 4 centered around stomodeum, external depression at oral membrane
5 initial primordia from neural crest mesenchyme (week 4)
- single frontonasal prominence (FNP) - forms forehead, nose dorsum and apex
- nasal placodes develop later bilateral, pushed medially
- paired maxillary prominences - form upper cheek and upper lip
- paired mandibular prominences - lower cheek, chin and lower lip
Week 6 to 7
Gestational Age (GA week 8 to 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.

Week 5 to 8
Gestational Age (GA week 7 to 10)
<mediaplayer width='380' height='400' image="http://embryology.med.unsw.edu.au/embryology/images/9/92/Stage15to22_head_icon.jpg">File:Stage15to22 head 01.mp4</mediaplayer> |
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.

Week 9
Gestational Age (GA week 11)
Secondary Palate Development
<mediaplayer width='350' height='350' 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. The lower jaw has been removed and the view shows the roof of the oral cavity and the maxilla (upper jaw) and lip.

Animation shows an anterior view of the developmental sequence of secondary palate formation. The frontal region of the head has been removed to show the changes within the oral cavity. Secondary palate formation is the growth of the palatal shelves towards the midline, from top to bottom:
