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)
Esophageal Phase
Bolus is transported to the lower esophageal segment
Iowa Oral Pressure Instrumentation
measures tongue force
Modified Barium Swallow Study (MBSS)
video radiographically recording a swallow of an individual who has ingested a bolus of food or liquid that has barium in it (can see both lateral and anterior view of the structures active during swallowing)
Fiber Endoscopic Evaluation of Swallowing (FEES)
allows direct visualization of pharyngeal space during swallowing by means of fiber optic technology (no radiation involved)
Mandibular Branch of V Trigeminal Nerve
the mandibular branch of the V trigeminal nerve innervates facial sensation for the mandible; including lower dentition
Maxillae
second largest face bone
Maxillae make up ____ of the hard palate and the horizontal plate of palatine bone makes up the other ___
3/4 and 1/4
Bones of the Cranium
ethmoid, sphenoid, frontal, parietal, occipital, and temporal
Buccal Cavity
from lips and cheeks, gums and teeth to the area behind the third molar
Oral Cavity
bounded by teeth, faucial pillars, hard palate, and tongue
Superior Longitudinal Muscle
elevates tip of tongue
Inferior Longitudinal
shortens tongue tip, tip down
Transverse
narrows and elongates tongue
Vertical
flatten tongue
Genioglossus
makes up the bulk of the tongue, the strongest and largest extrinsic; (anterior retract tongue; posterior protrudes tongue) both depress tongue
Styloglossus
draws tongue up and back
Hyoglossus
pulls sides of the tongue down
Masseter
elevate mandible
Temporalis
elevate mandible quickly
Orbicularis Oris
constricts oral opening
Risorius
retract lips at the corners
Buccinator
moves food onto molars, constricts oropharynx
Levator labii superioris
elevates the upper lip
Zygomatic minor
elevates the upper lip
Levator labii superioris alaeque nasi
elevates the upper lip
Levator anguli oris
draws the corner of the mouth up and medially
Zygomatic Major
elevates and retracts the angle of the mouth
Depressor Labii Inferioris
dilates the orifice by pulling the lips down
Depressor Anguli Oris
depresses corners of the mouth and helps compress the upper lip against the lower lip
Mentalis
elevates and wrinkles the chin and pulls the lower lip out
Platysma
depresses the mandible
Palatoglossus
elevates the tongue, or depresses the soft palate
