1. Superior Constrictor
2. Horizontal fibers of palatopharyngeus
Which CNs and muscles are involved in progressive CONTRACTION & ELEVATION of PHARYNX? (3)
(Pharyngeal Plexis)

1. Interarytenoids (transverse & oblique)
2. Lateral Cricoarytenoid (LCA)
2. Thyroartenoid (body of VF)
Which CN/muscles INVERT EPIGLOTTIS to protect the larynx?
1. Thyrohyoid
2. Possibly Aryeppiglottic
What is a major contributor of UES opening & is part of the inferior pharyngeal constrictor?

Its attached anteriorly to the laminae of the cricoid cartilage.
Does the UES relax or tense during the swallow?
Which CN deals with both the motor & sensory of cough?
CN: X (input and output)
Which CNs deals with both the motor & sensory of gag-reflex?
CN: IX (sensory) - input
CN: X (motor) - output
What are some changes associated with NORMAL AGING & SWALLOW?
1. Tongue muscle atrophy (leads to reduced lingual propulsion)
2. Hardening of flexible cartilages & ossification
3.Larynoptosis- Sagging of larynx
4. Increased transit times (delayed0
5. Residue increased
6. UES opening reduced
7. Swallow response time delayed
8. Frequent penetration into airway but NEVER beyond VFs (aspiration is NEVER normal)
9. Reduced sensations
10. Reduced cough reflex
Can dysphagia & aspiration be a consequence to normal aging?
ORAL: 1-1.5 seconds

PHARYNGEAL: ~1 second

ESOPHAGEAL: 8-12 seconds
During what stage of the swallow does the epiglottis retracts to cover entrance of the larynx?

What happens next in this stage?
Pharyngeal stage

The CRICOPHARYNGEAL relaxes (UES opens)
What are 4 protective mechanisms regarding airway and prevents aspiration?
1. Retraction of epiglottis
2. Elevation & forward movement of hyoid and larynx
3. Adduction of true vocal folds
4. Sphincter squeezing/closure of laryngeal vestibule
Which neurogenic disease results in spasticity and incoordination of oropharyngeal and respiratory muscles creating functional problems with swallowing?
Multiple Sclerosis (demyelinating disease

Autoimmune process that involves destruction of MYELIN; Nerve impluses slowed or halted.
dysphagia signs stem from the oral and
Which neurogenic disease results in pharyngeal stage disorders of lingual chorea and tachyphagia (abnormally rapid eating or bolting of food)?
Huntington's Disease (Extrapyramidal Tract)
Which neurogenic disease results in rigidity and impaired lingual movement, minimal jaw opening, abnormal head and neck posture, and impulsive eating behavior and may even have silent aspiration?
Parkinson's Disease (Extrapyramidal Tract)
Which neurogenic disorder always results dysphagia and exercises are contraindicated because they lead to future fatigue of musculature?
Which neurogenic disorder results in progressive fatigue with use and often affects muscles innervated by the bulbar nuclei?

What is recommend for this disease?
