Test 3 Flashcards
Three immobile articulators
alveolar ridge, hard palate, and teeth
Soft palate
mobile articulator for /m/ and /n/ sounds
Cheeks
play a role in changes of resonance of the cavity
Teeth
used in the production of a variety of speech sounds
When do you start getting teeth?
between 6-7 months
When do you start shedding teeth?
6-7 years
Occlusion
the relationship between mandibular and maxillary arches with reference to dentition
Class I Occlusion
neutroclusion- normal orientation
Class I Malocclusion
normal molar orientation but deviation in anterior portion of arch
Class II Malocclusion
mandible retracted
Class III Malocclusion
mandible overlaps maxilla
Mastication
preparation of food for swallow
Deglutition
swallowing
Dysphagia
disorders of swallowing at any stage in the process
Cricopharyngeus
the component of the inferior constrictor involved in the upper esophageal sphincter
UES
upper esophageal sphincter
Pharyngoesophageal
upper esophageal sphincter, immediate esophageal region, and immediate pharyngeal region
Apneic period
in swallow, usually stop breathing
As Infant Grows
larynx and epiglottis drops, oral cavity grows, teeth erupt, tongue ceases anterior movement during swallow
Oral Preparation Stage
the preparation stage of the swallow (mastication)
Oral Stage
the “initiation stage” for swallow
Pharyngeal Stage
airway protection (vocal folds clamp), pressure generation (hyoid and larynx elevate and move forward), bolus movement (moves bolus posteriorly and into oropharynx)
