Chapter 01: Oral Cavity
Brand/Isselhard: Anatomy of Orofacial Structures, 9th Edition
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.
REF: p. 3
OBJ: To describe the boundaries and sub-boundaries of the oral cavity and the structures in each
area
NAT: CDA: GC I.A.6. Identify basic oral anatomy and physiology, including but not limited to: oral
cavity. TOP: BLOOM: Remembering

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 may grow
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.
REF: p. 5
OBJ: To define the terms vestibule, oral cavity proper, mucobuccal fold, frenum, alveolar mucosa,
gingiva, exostoses, torus palatinus, and torus mandibularis
NAT: CDA: GC I.A.2. Identify basic oral anatomy and physiology, including but not limited to: bones.
TOP: BLOOM: Remembering
3. Contraction of which muscle raises the tongue upward?
a. Mylohyoid
b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal
ANSWER: A
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.
REF: p. 7
OBJ: To define the landmarks in the floor of the mouth and the hard and soft palate and the
structures that form them
NAT: CDA: GC I.A.4. Identify basic oral anatomy and physiology, including but not limited to:
muscles. TOP: BLOOM: Remembering
