  1. The face and its associated tissue begin to form during which week of prenatal development
    fourth
  2. previous to the fourth week of prenatal devemlopment the stomodeum is sealed off from the foregut by the
    oropharyngeal membrane
  3. the oropharyngeal membrane is composed of
    endoderm and ectoderm
  4. the five main tissue swellings prominences or processes that join/fuse together to form the human face include all EXCEPT:

    the frontal nasal processes
     the paired lateral nasal processes
    the paired maxillary processes
    the paired mandibular processes
    the paired lateral nasal processes
  5. in the embryonic development of the face and oral cavity, the first branchial arch or mandibular arch give rise to the
    base of the tongue, mandible, lateral parts of the hard palate, and the soft palate
  6. which of the following facial structures is formed from the mandibular arch

    forehead
    lower face
    philtrum
    nose
     second branchial arch
    lower face
  7. the frontonasal process of the early embryo give rise to all of these EXCEPT

    upper face
    maxillary incisors
    maxillary canines
    bridge of nose
    maxillary canines
  8. the frontonasal processes is a swelling that appears over the developing brain in the embryo and forms the

    forehead
    otic palcodes
    mandibular arch
    neck area
    branchial arches
    forehead
  9. the philtrum of the upper lip forms from the

    mandibular processes
    medial nasal processes
    lateral nasal processes
    nasal placodes
    maxillary processes
    medial nasal processes
  10. the maxillary process of the early embryo gives rise to all of these EXCEPT

     sides of upper lip
    secondary palate
    cheeks
    alae of the nose
    alae of the nose
  11. the best definition of a Placode is
    thickened ectoderm that will develop into sensory organs
  12. in the development of the oral cavity the embryonic origin of area A in figure 1 is the
    frontonasal process
  13. the most common defects of ororfacial development are, unilateal and bilateral cleft lips.  The facial abnormalities are the failure of which facial processes to fuse with the maxillary processes
    maxillary process and medial nasal process

    it contains Reicherts cartlidge
    it forms into the muscles of mastication
    it is associated with the trigeminal nerve
    it contains reicherts cartilidge
  16. Recherts cartilage contributes to the formation of NONE of the following EXCEPT

    eardrum
    malleus

    true of false
    true
  20. the mandibular arch during the embryonic period is the

    fusion of the two mandibular processes
    swelling found superior to the stomodeum
    stucture that gives rise to the lateral nasal proceses
    posterior portion of the hard palate
    fusion of the two mandibular processes
  21. the overall growth of the face is in a superior and posterior direction in relationship to the cranial base

    true of false
    • false
    • the overall growth of the face is in an inferior and anterior direction in realtionshop to the cranial base
