Question Answer
the voluntary control of the swallow is under ___ control. supratenetorial.
Do people have a dominant swallow hemisphere? yes.
The involuntary phase of the swallow is under ... infrantentorial control.
What are some things that can affect a swallow? stroke, hemorrhage, tumors, dementia, TBI, neurological disease: MS, Parkinson, supranuclear palsy, cerebral palsy,
Dysphagia can arise in what kinds of situations? (think of people of all ages.) neuromuscular disorder, critical illness, prematurity, genetic disorder
Where is the infratentorial located? Beneath the tentorium of the cerebellum
the supratentorium is how much of the brains weight? 85 % - heaviest part of the brain. Location of cerebrum
what is involved in the oral part of a swallow? 1. hard and soft palate 2. labial - lips 3. lingual - tongue 4. buccal - cheeks 5. maxilla (upper) mandibular (lower) 6. oropharynx - can see with open mouth 7. nasopharynx -
what does the nasopharynx connect? nose and mouth allowing you to breathe
where is the nasopharynx located? space above the soft palate at the back of the nose.
oral phase why is labial close important? lip closure - hold food inside
oral phase why is soft palate elevation important? velopharyngeal closure
oral phase lingual, labial, buccal strength and range importance? bolus formation
oral phase posterior lingual propulsion importance? bolus force during swallow transit
oral phase buccal strength importance? (2) 1. can suck from a straw 2. prevent food from lodging in lateral sulcus/sulci
oral phase mandibular range is needed why? opening and closing of the mouth
oral phase lateral rotary mandibular movement is important for? mastication
Dysfunction oral phase leakage of food
dysfunction oral phase pocketing of food where? lateral and anterior sulci
oral phase dysfunction lingual propulsion can be weak
oral phase dysfunction mastication weak
oral phase dysfunction mandibular movement reduced lateral rotary for mastication
oral phase dysfunction maxilla and mandibular inability to open / close
oral phase dysfunction sensation reduced oral sensation to know food is still within the mouth.
If you have reduced lingual function means? reduced mastication
if you have reduced lingual elevation means reduced intra oral pressure due to reduced tongue to palate contact
reduced anterior to posterior tongue movement means.. slow weak bolus transit. Sulci residue increases.
Children commonly have a tongue thrust, what happens with the bolus? leakage from the oral cavity then.
impaired buccal strength mandibular movement? impaired mastication
impaired buccal strength altered mandibular / maxilla alignment? Impaired mastication
impaired buccal strength reduced oral sensation? dispersal of material through oral cavity and loss of oral control.
When can you say food has become a pharyngeal phase disorder? one bolus reaches faucial arches and swallow is triggered.
pharyngeal phase disorder delayed swallow response? premature spillage of the base of the tongue
pharyngeal phase disorder the longer the delay in a swallow initiation then... the greater the risk of aspiration
pharyngeal phase disorder absent swallow reflex or response... material resting in the vallevulae 10 seconds or more... aspiration of bolus will occus.
Where will food/liquid go if you have reduced VP closure? bolus enters nasal cavity.
reduced vp closure has reduced oral pressure during oral phase of swallow
reduced VP closure occurs with what diseases? oral cancer, soft palate resection, cleft palate, sub mucous cleft, some neurological impairments
Is reduced phayngeal peristalsis unilateral, bilateral, both? can be bilateral or unilateral
if you have a reduced pharyngeal peristalsis residue can fall where? into the airway after a swallow.
When you have reduced pharyngeal constriction food can go where? (3) 1 valleculae 2. posterior pharyngeal wall 3. pyriform sinus
cricopharyngeal dysfuntion is normally in a stage of constant relaxation or contraction? contraction
Cricopharyngeal dysfunction relaxes when? during a swallow.
In cricopharyngeal dysfunction if no relaxation is present bolus remains where? pyriform sinus
why does aspiration occur in cricopharyngeal dysfunction? residue spills into trachea over the arytenoid cartilage
Reduced laryngeal elevation paralysis / weakness of what muscles? strap muscles
Surgical resection/reconstruction of the strap muscles wiht reduced laryngeal elevation causes what? material falls onto the top of the larynx, resting on the vocal cords. cords abduct, reside falls into the airway.
Muscles that lower the hyoid are? TOSS: Thryohyoid Ohmohyoid Sternohyoid suprahyoid
Muscles that elevate the hyoid? My great dane smells Mylohyoid Geneohyoid Digastric stylohyoid
Which two nerves help squeeze the pharyngeal constrictors? CN IX and X
