    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

    lower face

    alae of the nose
    alae of the nose
  11. the best definition of a Placode is

  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 is called the mandibular arch
    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

    lower portion of the hyoid bone
    upper portion of the hyoid bone
    upper portion of the hyoid bone
  17. the six branchial arches, groove, and the three pharyngeal pouches are the embryonic precursors to which of the following structures of the human adult, ear, neck, thyroid, and trachea

    mandibular/1st branchial arch
    branchial groove
    hyoid/2nd brachial arch
    3rd brachial arch
    4-6 brachial arch
    1st pharyngeal pouch
    2nd pharyngeal pouch
    3 pharyngeal pouch

    • lower portion of hyoid bone
    • muscles of the larynx
    • auditory tubes
    • palatine tonsils
    • thymus gland
  18. the branchial arches are six pairs of stacked bilateral swellings of tissue that appear inferior to the stomodeum.  The branchial arches include the maxiallry arch

    true of false statements
    the first statement is true the second is false
  19. all three embryonic layers are involved in facial development

    true of false
  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
  22. the paired maxillary processes fuse at the midline to form the mandibular arch

    true of false
    • false
    • paired mandibular processes then fuse at the midline to form the mandibular arch.
