MULTIPLE CHOICE
1. A diastema is a space between two teeth in the same arch. When this occurs between the
maxillary central incisors, it is often the result of a pronounced labial frenum.
a. Both statements are true.
b. The first statement is true; the second statement is false.
c. The first statement is false; the second statement is true.
d. Both statements are false.
ANSWER: A
A space, or lack of contact area, between any two teeth in the same arch is called a diastema. When a
diastema occurs between the maxillary central incisors, it is often the result of a pronounced labial
frenum extending to the crest of the alveolar ridge and possibly over the ridge. This band of firm
connective tissue causes the erupting incisors to be pushed aside resulting in a diastema, or space.
Correction of a diastema usually involves surgical removal, or cutting, of the frenal tissue between
teeth.

2. Torus palatinus is seen on the
a. soft palate
b. hard palate
c. alveolar ridge
d. oral pharynx
ANSWER: B
Torus palatinus is excess bone growth and occurs in the midline of the hard palate. It maygrow to
varying sizes and is generally only a problem when the construction of a maxillary denture is
necessary. In health, such bony protuberances, or excess bone growths, do not occur on the soft
palate, alveolar ridge, or oral pharynx.Test Bank for Anatomy of Oriented Structure 8th edition.pdf file:///C:/Users/HP/Downloads/Test%20Bank%20for%20Anatomy%2...

3. Contraction of which muscle raises the tongue upward?
a. Mylohyoid
b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal

3 of 68 7/20/2024, 1:46 AM Contraction of the mylohyoid muscle raises the tongue. The palatopharyngeal muscle and the
palatoglossal muscle form the posterolateral borders of the oral cavity. There is not a muscle by the
name of levator glossal.

form them

muscles. TOP: BLOOM: Remembering
4. The oral vestibule is partially bordered by the lips and cheeks. The oral cavity proper extends
posteriorly to the soft palate.
a. Both statements are true.
b. The first statement is true; the second statement is false.
c. The first statement is false; the second statement is true.
d. Both statements are false.
ANSWER: B
The oral vestibule is the space or potential space that exists between the lips or cheeks and teeth. In
an edentulous person, the vestibule would extend between the lips or cheeks and the alveolar
ridges. The oral cavity proper is surrounded by teeth or alveolar ridges and extends all the way back
to the palatine tonsils. This includes the region from the floor of the mouth upward to the hard
and soft palates.

5. Each of the following is true of the uvula EXCEPT one. Which one is the EXCEPTION?
a. It is located at the most posterior portion of the hard palate.
