1

Where is the oral vestibule?

The space between the lips and teeth

2

What are the two kinds of aspiration?

(2)

Food goes up the nose

Food goes down the lungs

3

What is silent aspiration?

Food goes down the lungs without the person realizing it.

4

What is the difference between striated & smooth tissue?

Striated is voluntary, smooth is involuntary

5

What part of the esophagus is composed of striated muscle?

The upper third

6

What part of the esophagus is composed of smooth muscle?

The lower two thirds

7

What innervates the esophagus?

Vagus & sympathetic divisions of the nervous system

8

Vagal activity increases ______.

Esophageal activity

9

What makes up the Upper Esophageal Sphincter (UES)?

(2)

Cricoid lamina

Cricopharyngeal muscle fibers (inferior constrictor)

10

What does the Upper Esophageal Sphincter (UES) do?

(2)

Prevents air from entering the esophagus during respiration

Prevents material from reflexing back up the esophagus and into the pharynx

11

What does the Lower Esophageal Sphincter (LES) do?

Prevents gastric reflux

12

What are the four phases of swallowing?

Oral Prep Phrase

Oral Transport Phase

Pharyngeal Transport Phase

Esophageal Transport Phase

13

What is the Oral Prep Phase?

(4)

Food enters mouth and is chewed

Bolus is prepped

Saliva is incorporated into food

Liquid is collected for drinking

14

What is the Oral Transport Phase?

Food is moved from the front of the mouth to the back of the mouth

15

What is the Pharyngeal Transport Phase?

(2)

Food is transferred to the pharynx towards the esophagus

The velopharyngus, vocal folds, and epiglottis are closed

16

What is the Esophageal Transport Phase?

Food is transferred into the esophagus

17

Which swallowing phases are voluntary?

(2)

Oral Prep Phrase

Oral Transport Phase

18

Which swallowing phases are involuntary?

(2)

Pharyngeal Transport Phase

Esophageal Transport Phase

19

What happens to the tongue during the Oral Prep Phase?

It is dished and moves posteriorly

20

What are the three types of salivary glands?

Submandibular (under jaw)

Sublingual (under tongue)

Parotid

(There are other smaller glands)

21

What does saliva do?

(4)

Maintains oral moisture

Reduces tooth decay

Assists in digestion

Holds bolus together

22

What are the two different kinds of saliva?

Viscous (watery)

Serous (thick & mucousy)

23

What happens during the Oral Phase?

(2)

Bolus is transported from anterior mouth to mid oral cavity via tongue

Tongue touches velum & faucial pillars triggering the velum

24

What triggers the Pharyngeal Phase?

The bolus passing over the back of the tongue

25

What happens during the Pharyngeal Phase?

(2)

Airway is protected

Bolus is moved

26

How is the airway protected during the Pharyngeal Phase?

(4)

Velopharynx is closed

Hyo-larynx is pulled up and forward

Vocal folds close

Eversion of the epiglottis

27

What makes the bolus move during the Pharyngeal Phase?

(3)

Peristalsis - progressive contraction of the pharynx

Pressure behind the bolus

Lubrication- serous saliva by the parotid glands

28

What is the path of the bolus during the Pharyngeal Phase?

(3)

It moves from the back of the tongue and valleculae

It separates into two equal parts and course around larynx & epiglottis through the pyriform sinuses

The two halves join once they reach the esophagus

29

What happens during the Esophageal Phase?

(4)

Upper esophageal sphincter is relaxed

Generation of low pressure in front of the bolus

Esophageal peristalsis (coursing contraction & relaxation

Dilation of the lower esophageal sphincter

30

What happens to airflow when we swallow?

We slightly exhale then have a period of apnea
