These prominences are derivatives of first arch. This arch will give rise to all vascular and neural supply of this area. The stomodeum is limited superiorly by the presence of frontonasal eminence and inferiorly by the mandibular arch stomodeum.

Anterior part of alimentary tract, ectodermal in origin and line with cuticle; cast with molt. (Syn. foregut) [McLaughlin, 1980]. Anterior part of alimentary tract. Four branchial grooves are present: the stomodeum is well-marked, and the bucco-pharyngeal membrane has disappeared. The rudiments of the limbs are seen as short buds, and the Wolffian bodies are visible (Fig. 59 ) Als Stomodeum wird in der Embryogenese die Ausbuchtung des Ektoderms bezeichnet, aus der sich später die Mundhöhle entwickelt. Die Ausbuchtung entsteht beim Menschen ab dem 22. Tag. Sie bricht ca. ab dem 23. Tag auf und es entsteht eine Öffnung, der spätere Mund
The determination of the stomodeum begins at the end of gastrulation, and the development of the ectodermal mouth invagination is induced by the endoderm when the anterior end of the archenteron comes in contact with the ectoderm of the presumptive mouth region cardiovascular embryology The cardiovascular system begins to develop during week 3. Mesenchymal cells derived from the mesoderm form endothelial tubes which join to form the primitive vascular system (The Developing Human, 8th ed., p. 286, fig. 13-1) Certaines illustrations, portant sur des malformations, peuvent avoir un aspect choquant pour les non professionnels, en particulier les enfants 1.

The vertebrate oral region represents a key interface between outer and inner environments, and its structural and functional design is among the limiting. Along the rostrocaudal axis, the head folds to form primitive stomodeum which line by ectoderm, separated the gut by buccopharyngeal membran Proctodeum and Stomodeum The proctodeum (anal pit) is the primordial anus , and the stomodeum is the primordial mouth . In both of these areas ectoderm is in direct contact with endoderm without intervening mesoderm, eventually leading to degeneration of both tissue layers Our conclusion, based on the location of the chaetal sac, the folding of the archenteron, and the relative locations of the stomodeum, anus, and chaetal sac in the earliest swimming larval stage, is that the blastopore becomes the opening immediately adjacent to the chaetal sac in the larva and thus forms the anus Stomodeum from ZOO 3603C at Florida International Universit

The facial swellings, formed mainly by the first pair of the pharyngeal arches, constitute the boundaries of the stomodeum: the frontal swelling cranially and the paired maxillary and mandibulary swelling laterally The primitive oral cavity, or stomodeum, is lined by stratified squamous epithelium called the oral ectoderm. Most of the connective tissue cells underlying the oral ectoderm are neural crest , ectomesenchyme , or neuroectoderm ; these cells are thought to be responsible for the development of teeth Fertilized Egg Zygote The primitive mouth Stomodeum Highest point of the alveolar ridge.

The mouth is developed partly from the stomodeum, and partly from the floor of the anterior portion of the fore-gut. By the growth of the head end of the embryo , and the formation of the cephalic flexure , the pericardial area and the buccopharyngeal membrane come to lie on the ventral surface of the embryo The stomodeum is lined by ectoderm and therefore the mucosa of all of these swellings is derived from ectoderm. The root of the tongue develops from a primitive swelling caudal to the tuberculum impar -- the copula (hypobranchial eminence) -- at the level.
