Dysphagia Screening
Pass/Fail, admin’d by nurses, assess risk
Role of saliva
lubricates and dilutes bolus for swallow.
What is saliva made of
an enzyme for digestion and mucus for lubrication
Salivary glands, viscous, serous, or mixed
Parotid: viscous only
Submandibular: mixed more serous
Sublingual: mixed more viscous
Tongue sensory innervation:
2 types and 2 zones
Types:
General: anterior 2/3 = CNV posterior= CNIX
Special: Taste
Anterior: VII Posterior=CNIX
Tongue motor innervation
CNX= pharyngeal branch of vagus -> palatal glossus CNXII = extrinisic and intrinsic muscles.
3 extrinsic muscles of the tongue and what they do.
- Hyoglossus: depresses sides of tongue
- Styloglossus: elevates the sides of tongue
- Genioglossus: protrudes tongue out
What do intrinsic muscles of the tongue do generally for the bolus?
hold the bolus
4 intrinisc muscles of the tongue and how they move
Super Longitudinal: elevates apex of the tongue
Inferior Longitudinal: depresses apex
Transverse: lateralizes (Left and right)
Vertical: Flattens
Parts of the hard palate (4)
Maxillae: anterior 2/3 of palate
Palatine
Superficial layer of keratinize (waterproof)
Rugae - Ridges that help move the bolus back
What are the 4 muscles of the velum and what do they do
Tensor Veli Palatini: pulls laterally and downward
Levator veli palatini: elevates and retracts
Palatoglossus: connects palate with tongue to close off the back of the oral cavity
Muscularis Uvulae: shortens and elevates
Motor Innervation for soft palate
CNV + CNX
Sensory innervation for soft palate
CNV + CNIX
3 constricter muscles of the pharynx in order
Superior pharyngeal constrictor
Middle pharyngeal Constrictor
Inferior pharyngeal constrictor
Innervation of the pharynx
pharyngeal plexus which is the pharyngeal branch of CNX and CNIX
Stylopharyngeus innervation
CNIX - motor
Palatopharyngeal innervation
Pharyngeal branch of CNX
