Oral Function, Swallowing and Speech Flashcards
swallowing stages
buccal [v]
pharyngeal n[iv]
oesophageal [iv]
function of swallowing
feeding - bolus through lower pharynx and eodophagus to sotmach
protective - prevents entering airway
swallowing liquids
gathered on tongue, anterior to pillar of fauces
sepated by posterior oral seal
properlled oropharyn and hypopharynx to oesophagus
swallowing solid bolus
accumualtes on pharyngeal tngue and vvallecula, no true oral seal, tongue to hyopharynx and oesophagus
key points of swallowing
liquids swallowed from mouth, proper oral seal
solids swallowed from oropharynx, no oral seal
both rapidly move from hypophyarynx to laryngeal inlet
swallowing tongue movements
forward movement in occlusala nd opening phase, squeeze back mechanisms, processed
swallowing events tongue
propulsion of food
prevention of reflux
protecting airway
duration depends
prevention of reflux
elevation of soft palate
tongue contacts pillar of fauces and poserior pharyngeal wall
upper oesophageal sphincter - reflex from os to pharynx
lower - reflux from stomach to oeso
erosion
stomach acid roding teeth
palatal anterior
attrition
tooth wear occlusally caused by contact in occluding teeth
bruxism, parafunction
abrasion
usually through biting/chewing objects in teeth, combned erosion and abrasion
acid weakens, more susceptble
abfraction
stress lesions
flexure and fatigue of teeth away from point of loading
airway protection
upward and forward pharynx movement
closure of laryngeal inlet [aryepiglottic muscles, epiglottis]
abduction of vocal folds, stop breathing [apnoea]
dysphasia
specific language disorder
damage to brain, brocas, wernicke area
dysarthria
difficulty speaking, problems with muscles used in speech
neruomuscular defects
lesions in nerual pathways, cranial nerves, vocal musces
odynophagia
extreme pain when swallowing
oral causes of language and speech defects
malocclusoons, loss of teeth, cleft lip/palate, tongue, dry mouth
cleft palate
oral and nasal cavitiy not seperated, speech has nasal quality, palatal defect needs fixed
tongue issues related to language/speech defects
tongue tie, partial atrophy, tongue stuf
xerostomia
dry mouth
impeded speech, inadequate saliva, hard to pronounce words, cant speak, cant swallow and speak nornally
denture related speech issues
restricted tongue space, base too thick, atifical teeth not set properly
loss of teeth + SPEECH sound ability
maxillary anterior - F and V lower lip on incisors
occlusal plane - f v ph
replacement of upper teeth
ask questions to get an idea of natural speech
embouchure
postion and use of lips tongue and teeth wind instrument
important social history
