Show Answers:

  1. Oral epithelium is classifed as:
    Stratified squamous epithelium
  2. The turnover time for all types of epithelium is higher compared to connective tissue. The rapid turnover time is the result of high levels of mitosis in the deepest cells near the basement membrane.
    Both the statement and reason are correct and related
  3. Where is the lamina propria located?
    connective tissue proper region of oral mucosa
  4. What type of tissue makes up the bulk of the lamina propria of the oral mucosa?
    connective tissue
  5. Where is the capillary blood plexus located in the lamina propria of the oral mucosa?
    between the superficial deeper layers
  6. The lamina propria of the attached gingiva is directly attached to the underlying bone acts as a periosteum and thus is termed [blank1].
  7. The basal layer of oral mucosa generally has:
    cells undergoing mitosis
  8. Which of the following is a deep tissue that may or may not be present in the oral mucosa, overlies bone or muscle in the oral cavity, and usually contains loose connective tissue and may also contain adipose connective tissue or salivary glands?
  9. Which of the following is an intermediate protein filament found in calloused epithelial tissues consisting of opaque waterproof substance?
  10. Attached gingiva is found between the:mucogingival junction and the free gingival groove.
  11. The attached gingiva and buccal mucosa are mainly pinkish in color and not reddish due to the:
    increased thickness of the epithelial layers
  12. Keratohyalin granules are located in which of the following epithelial layers?
    Stratum granulosum
  13. Which of the following is the immature connective tissue formed during the initial repair of the skin or oral mucosa?
    granulation tissue
  14. The dorsum of the tongue has on it many papillae of different kinds. The kinds of papilla may include:
    Circumvallate, fungiform, filiform, and foliate
  15. Melanin is a pigment formed by melanocytes, derived from the neural crest cells, injecting cytoplasmic granules or inclusions called [blank1] into neighboring, newly formed epithelial cells of the basal layer
  16. Which tissue listed below is CLOSELY associated with parakeratinized stratified squamous epithelium?
    attached ginigva
  17. The buccal mucosa may contain Fordyce's spots, which are:
    deposits of sebum from misplaced sebaceous gland tissue
  18. Stippling is associated with which of the following?
    attached gingiva
  19. The mucogingival junction is absent from which of the following surfaces?
    maxillary palatal surface
  20. Which of the following areas of the oral cavity is categorized as a lining mucosa?
    soft palate
  21. Which of the following statements concerning pigmentation in the oral cavity is CORRECT?
    Pigmentation serves no known function in the oral cavity.
  22. Which of the following mucosa is found on the dorsal and lateral surface of the tongue in the form of the lingual papillae?
    specialized mucosa
  23. Which of the following body of the tongue lesions appear first as red, then paler pink, and finally white patches?
    geographic tongue
  24. What type of cell listed below has prominent granules in the cytoplasm that form a keratin chemical precursor?

  26. Keratinized stratified squamous epithelium may readily be transformed into a nonkeratinizing type of epithelium in response to frictional or chemical trauma in such case it undergose hyerpkeratinization.
