Fusion of lateral nasal process with maxilla bone will form A- nostrils. B- maxillary sinus.

Question

Anatomical structures are more diverse in the mouth than in any other region. ?The human face begins to form during the 4th week of embryonic development. ?By the 6th week the external face is completed. ? Between the 6th and 8th weeks the development of the palate subdivides nasal and oral cavities. ? This development continues into the 12th week with completion of the soft palate.
3. DEVELOPMENT OF FACE ? Face develops from 3 prominences that surround the stomatodeum 1. One frontonasal process 2. Right and Left maxillary processes (from first pharyngeal arch) ? 3- Right& left Mandibular processes (from the first pharyngeal arch). ?N. B. Stomodeum is a depression bounded cranially by a bulging produced by the brain and caudally by a bulging produced by the pericardial cavity. * From each side of lower part of frontonasal process two mesodermal processes appear called medial& lateral nasal processes (they will give the nasal cavities in the future.
4. Maxillary process DEVELOPMENT OF FACE Mandibular process Mandibular process Maxillary process Fronto-Nasal process.
