The flashcards below were created by user anatomy2012 on FreezingBlue Flashcards. What would you like to do?


  1. the development of the palate begins in the _______week of the embryoinc period and concludes during the _____ week of the fetal period of prenatal development
    • 5th
    • 12 week
  2. the primary palate is derived from which embryonic process(es)

    first branchial or mandibular arch
    maxillary processes
    frontonasal process
    none of these
    frontonasal process
  3. the intermaxillary segment gives rise to all of these structures EXCEPT

    primary palate
    maxillary incisor teeth
    septum of the nose
    maxillary canine teeth
    maxillary canine teeth
  4. in the embryonic development of the face and oral cavity, the first mandibular arch (first brachial arch) gives rise to

    this one has the right answer quiz 2 doesn't
    sides of the hard palate, soft palate, body of the tongue and mandible
  5. the secondary palate is derived from which embryonic process (es)

    frontonasal process
    maxillary proceses
    laternal nasal processes
    none of these
    maxillary processes
  6. what are the three consecutive stages of palate development
    • formation of the primary palate
    • formation of the seondary palate
    • completion of the final palate
  7. palatal fusion allows the fusion of swellings or tissue from different surfaces of the embryo

    true of false
    true
  8. explain how the development of the tongue accomodates the development of the palate
    As the developing tongue muscles begin to function the tongue contracts and moves out of the way of the developing palatal shelves so they can "snap" into the horizontal postion
  9. the fusion of teh two palatal shelves with the primary palate is dependent on the

    ingrowth of the maxillary arch
    change in postion of the paranasal sinuses
    continued vertical growth of all the proceses
    change in the position of the tongue, elongation and medial movement
    change in the postion of the tongue elongation and medial movement
  10. the secondary palate gives rise to

    only the posterior two thirds of the hard palate and the posterior maxillary teeth

    only the anterior one third of the hard palate and the maxillary incisor teeth

    only the soft palate, its uvula and the median palantine raphe
    only the posterior two thirds of the hard palate and the posterior maxillary teeth
  11. what structure partially separates the nasal and oral cavities in the fifth week of prenatal development

    maxillary process
    primary palate
    final or definitive palate
    mandibular arch
    nasal septum
    primary palate
  12. in the case of the cleft uvula what went wrong
    palatal shelves (secondary palate) did not fuse completely in the back
  13. what type of facial clefting is displayed in this picture

    it shows a complet bilateral cleft of the lop and alveolar process, with bilateral cleft of the primary palate
    picture
  14. in the embryonic development of the parts of the oral cavity the tongue is derived from the

    first, second, third, fourth
    first branchial arch which forms the body and the second third and fourth branchial arches, which form the base
  15. Why is the tongue innervated by so many different nerves
    becasue it comes from so many different areas that are sources of so many cranial nerves.
  16. the tongue develops between the fourth to eighth week of prenatal development

    true of false
    true
  17. tongue development begins as a triangular median swelling, the tuberculum impar

    true of false
    true
  18. the ____ is the opening to the thyroglossal duct
    foramen cecum
  19. match the following embryonic structure with it's eventual structure

    copula
    third fourth branchial arches
    lateral lingual swellings
    tuberculum impar
    • body of tongue
    • base of tongue
    • base of tongue
    • body of tongue
  20. the copula is formed from the fusion of mesenchyme of mainly the third and parts of the fourth branchial arches

    true of false
    true
  21. the foramen cecum is the beginning of the thymus

    true of false
    false the foramen cecum is the beginning of the thryoglossal duct
  22. the nasal septum forms from which process (es)

    frontonasal
    maxillary
    first branchial arch
    second branchial arch
    frontonasal process
  23. the nasal cavity forms at the same time as the palate

    true of false
    true
  24. facial development is completed during the 12 wek of prenatal development

    true of false
    true
