Lesson 4 Terms - Anatomy and Physiology of Articulation, Resonation, and Deglutition

Question 1

articulation

Answer 1

The process of bringing the mobile and immobile articulators into contact for the purpose os shaping the sounds for speech.

Question 2

vocal tract

Answer 2

The oral cavity, the pharynx, and the naval cavity.

Question 3

deciduous (shedding) teeth

Answer 3

The primary set of teeth.

Question 4

Successional teeth

Answer 4

Teeth in the mature dental arch that replaces corresponding teeth of the deciduous arch.

Question 5

occlusion

Answer 5

Closing.

Question 6

Class I occlusion relationship (neutroclusion)

Answer 6

The normal occlusion relationship characterized by the maxillary and mandibular molar relationship in which the maxillary first molar is retracted one-half tooth relative to the mandibular first molar.

Question 7

overjet

Answer 7

Condition of normal dentition in which the upper incisors project beyond the lower incisors.

Question 8

neutroclusion (Class I occlusion relationship)

Answer 8

The normal occlusion relationship characterized by the maxillary and mandibular molar relationship in which the maxillary first molar is retracted one-half tooth relative to the mandibular first molar.

Question 9

Class II malocclusion

Answer 9

The occlusal relationship characterized by the maxillary and mandibular molar relationship in which the maxillary first molar is retracted at least one tooth relative to the mandibular first molar.

Question 10

Class III malocclusion

Answer 10

The occlusal relationship characterized by the maxillary and mandibular molar relationship in which the maxillary first molar is advanced at least one tooth relative to the mandibular first molar.

Question 11

torsiversion

Answer 11

Twisted on the long axis.

Question 12

labioversion

Answer 12

Tilted toward the lip.

Question 13

linguaversion

Answer 13

Tilted toward the tongue.

Question 14

buccoversion

Answer 14

Tilted toward the cheek.

Question 15

infraversion

Answer 15

Inadequate eruption relative to the other teeth in the arch.

Question 16

supraversion

Answer 16

Excessive eruption relative to the majority of teeth in the arch.

Question 17

persistent open bite

Answer 17

Anterior dentition fails to occlude properly as a result of spur aversion of the posterior teeth.

Question 18

persistent closed bite

Answer 18

Posterior dentition fails to occlude properly as a result of supraversion of the anterior teeth.

Question 19

bolus

Answer 19

A mass of masticated food ready to be swallowed.

Question 20

nares

Answer 20

Nostrils.

Question 21

mastication

Answer 21

The process of chewing food.

Question 22

dysphagia

Answer 22

Disorder of swallowing.

Question 23

nasal regurgitation

Answer 23

Loss of masticated food or liquid through the nasal cavity.

Question 24

distroversion

Answer 24

Tilted away from the midline of the dental arch.

Question 25

mesioversion

Answer 25

Tilted towards the midline of the dental arch.
