Development of the Face
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. See also the movie (Quicktime | Flash) showing a similar view of human embryo faces between Carnegie stage 16 to 18.
