Deck 1: Oral Cavity

Question 1

A) It is located at the most posterior portion of the hard palate.
B) It is located at the midline.
C) It is a downwardly projecting muscle.
D) It is necessary for swallowing.

Answer 1

D
The uvula is a downwardly projecting muscular tissue located at the midline of the most posterior portion of the hard palate. It is NOT necessary for swallowing.

Question 2

Each of the following structures is located within the hard palate EXCEPT one. Which one is the EXCEPTION?

A) Incisive papilla
B) Rugae
C) Greater palatine foramina
D) The anterior and posterior pillars

Answer 2

D
The anterior and posterior pillars are located posterior to the soft palate. The posterior pillar is also called the palatopharyngeal arch or fold. The anterior pillar is also called the palatoglossal arch or fold. The tonsils lie between the anterior and posterior pillars. The incisive papilla and rugae are located on the anterior portion of the hard palate. The greater palatine foramina are located in the posterior portions of the hard palate lingual to the second and third maxillary molars.

Question 3

Torus palatinus is seen on the

A) Soft palate
B) Hard palate
C) Alveolar ridge
D) Oral pharynx

Answer 3

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.

Question 4

A generally healthy man in his forties is curious about "little raised yellow spots" on his buccal mucosa. He has noticed them in the past but they do not seem to cause problems or become larger, so hasn't previously asked about them. These areas are MOST likely

A) Vallate papillae
B) Kaposi's spots
C) Fordyce granules
D) Measles

Question 5

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.

C) The first statement is false; the second is true.
D) Both statements are false.

Question 7

Contraction of which muscle raises the tongue upward?

A) Mylohyoid
B) Palatopharyngeal
C) Palatoglossal

Question 8

The term for misplaced sebaceous glands occurring in the oral cavity is rugae. These harmless, yellowish granular structures occur in about 60% to 80% of the population.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false; the second is true.
D) Both statements are false.

Question 9

In the following illustration, structure "c" is the

Question 14

Which of the following is another term for tongue-tied?

A) Glossolalia
B) Ankyloglossia
C) Frenectomy
D) Glossitis

Question 15

Although a patient presenting with painful areas throughout the oral cavity or a child presenting with gingival bleeding in the presence of excellent oral hygiene should be monitored carefully, referral to a dental specialist or physician is not indicated. A patient with a red and painful tongue does warrant such a referral as does a patient with moderate plaque on all teeth.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false, the second is true.
D) Both statements are false.

Question 16

In the following illustration, structure "b" is the

A) Mucobuccal fold
B) Mucogingival junction
C) Maxillary labial frenum
D) Mandibular labial frenum

Question 17

Which structure is the MOST vascular in appearance?

A) Mucogingival junction
B) Alveolar mucosa
C) Labial frenum
D) Gingiva

Question 18

Fordyce granules normally function as

A) Taste buds
B) A characteristic of a malignancy
C) Sebaceous glands
D) An infectious viral illness

Question 19

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 is false.
C) The first statement is false; the second is true.
D) Both statements are false.

Question 22

Lymphoid tissues located at the base of the tongue are known as foliate papillae.

Question 23

Beneath the incisive papilla is an injection site called the greater palatine foramen.

Question 24

The ridge of bone that can be palpated in the upper posterior aspect of the vestibular space is referred to as the vestibular zygomaticoalveolar crest.
