DENTAL HYGIENE SEMINARS FINAL
EXAM WITH CORRECT QUESTIONS
AND ANSWERS 2025
1. What type of epithelial tissue is found in the area of the labial mucosa?
a. Simple squamous epithelium
b. Simple cuboidal epithelium
c. Stratified squamous epithelium
d. Stratified cuboidal epithelium
e. Stratified columnar epithelium - CORRECT-ANSWERSC. The type of tissue lining the area
of the labial mucosa is stratified squamous epithelium. The tissue is stratified, which means it
contains several layers. The surface cells are scale like or squamous in shape.
2. The tissue of the labial mucosa is considered what type of mucosa?
,a. Masticatory
b. Lining
c. Specialized - CORRECT-ANSWERSB. The type of tissue in the area of the labial mucosa is
considered lining mucosa. Lining mucosa is nonkeratinized stratified squamous epithelium,
and it is also found in the areas of the buccal mucosa, the floor of the mouth, the ventral
surface of the tongue, and the soft palate.
3. What type of epithelium is found on the neck?
a. Nonkeratinized stratified columnar
b. Nonkeratinized stratified squamous
c. Keratinized stratified columnar
d. Keratinized stratified squamous
,e. Nonkeratinized simple squamous - CORRECT-ANSWERSD. Skin is composed of keratinized
stratified squamous epithelium. The tissue is stratified, which means it contains several layers.
The surface cells are scale like or squamous in shape. The surface layers contain keratin.
4. Epithelial tissues are characterized by
a. much intercellular substance and few cells.
b. no intercellular substance.
c. little intercellular substance and many cells.
d. intercellular substance in surface layer only. - CORRECT-ANSWERSC. Epithelial tissue is
characterized by little intercellular substance and many cells.
5. The last visible layer is nonkeratinized stratified epithelium is
a. basal cell layer.
, b. prickle cell layer.
c. granular layer.
d. corneum layer. - CORRECT-ANSWERSB. The prickle layer is the last visible layer in
nonkeratinized stratified squamous epithelium.
6. The cells of the outer layer of keratinized stratified squamous epithelium
a. undergo constant mitosis.
b. contain large amounts of melanin.
c. are shaped like stars.
d. contain large amounts of keratin.
e. have several nuclei. - CORRECT-ANSWERSD. The corneum layer is the last visible layer in
keratinized tissue. It contains nonvital cells filled with large amounts of keratin.
7. Continuous replacement of cells is characteristic of which type of epithelium?
