[Stomatofacial morphogenesis. Some specifications].

The initial phases of the embryogenetic process are evaluated in order to define its mesenchymal matrix. The influence of cephalic neural crests on mesenchymal derivatives is also underlined. Finally paraxial and lateral mesodermal function on cranial development and brachial arches composition are described. A correlation is established between head and neck, neural crests, mixed and sensorial cranial nerves. Tongue and orbital cavity muscles are identified as paraxial matrix derivative organs.
