Four |Stages |of |Swallow |- |VERIFIED |ANSWER✔✔-Oral |prep
Oral
Pharyngeal
Esophageal

Nasopharynx |- |VERIFIED |ANSWER✔✔-Nasal |cavity |to |velum

Oropharynx |- |VERIFIED |ANSWER✔✔-velum |to |base |of |the |tongue

Hypopharynx |- |VERIFIED |ANSWER✔✔-base |of |the |tongue |to |the |vellculae |to |UES

Oral |Prep |Stage |- |VERIFIED |ANSWER✔✔-Swallow |phase |where |food/liquid |prepared |for |further |phases |of |
swallow.
Prior |to |oral |phase.
Tongue |moves |the |bolus |laterally |to |the |molars.
Crushing, |repetitive |movements |of |jaw |reduce |the |bolus |size.
Chewing |continues |reflexively |once |initiated, |but |may |be |volitionally |altered.
Food/liquids |are |formed |into |a |bolus.
Bolus |centralized |and |compressed |by |the |tongue |against |the |hard |palate |for |transfer |in |a |later |phase.

, Muscles |of |Mastication/Oral |Prep |- |VERIFIED |ANSWER✔✔-Temporalis |(raises |and |retracts)
Masseter |(elevates)
Lateral |pterygoid |(protrudes |mandible)
Medial |pterygoid |(lateralizes |mandible)
Buccinator |(oral |prep |muscle |pair)

Innervation |of |Mastication |- |VERIFIED |ANSWER✔✔-Cranial |nerve |V: |trigeminal

Salivary |Glands |- |VERIFIED |ANSWER✔✔-Submandibular |
Parotid
Sublingual

Important |in |digestion, |oral |health, |and |taste |facilitation
Produce |both |serous |and |mucous |components |to |aid |in |the |formation |and |lubrication |of |the |bolus.

Innervated |by |CNs |XII |and |IX

Mechanical |Receptors |in |the |oral |cavity |- |VERIFIED |ANSWER✔✔-Tongue
Teeth
Gums
Palate

Thermoreceptors |- |VERIFIED |ANSWER✔✔-Temperature

Senors |via |sensory |branch |of |CN |V

Chemoreceptors |- |VERIFIED |ANSWER✔✔-Taste

Mediated |by |CN |VII |(anterior |2/3 |of |tongue) |and |CN |IX |(posterior |1/3 |of |tongue)

Oral |Phase |- |VERIFIED |ANSWER✔✔-Waiting |bolus |is |propelled |posteriorly |(anterior |> |posterior |propulsion)
Bolus |moves |cohesively |from |the |oral |cavity |into |the |oropharynx
Key |structure |in |this |movement |is |the |tongue
Base |of |the |tongue |elevates |via |palatoglossus |(CN |IX, |X)
Velum |elevation |to |seal |nasopharynx |via |palatopharyngeus |and |levator |muscle |of |the |velum |palatini |(CN |X |
and |XI)

Intrinsic |Muscles |of |the |Tongue |- |VERIFIED |ANSWER✔✔-Superior |Longitudinal |Muscle: |shorten |superior |
aspect |(raise |tip) |and |create |concave |depression
Transverse |Muscle: |elongate |and |narrow
Vertical |Muscle: |flattens
Inferior |Longitudinal |Muscle: |shorten |tongue/depress |tip
