Question 1

How long does the oral transit stage last?

Answer 1

1 second

Question 2

When does the oral transit phase begin?

Answer 2

When mastication ends

Question 3

Phase of swallowing where tongue forms ramp and moves bolus from the oral cavity to the pharyngeal cavity; labial seal and nasal breathing is maintained

Answer 3

Oral transit

Question 4

What CN helps to retract the tongue and helps to form the tongue into ramp to move the bolus posteriorly?

Answer 4

V

Question 5

What tongue muscles does CN V control?

Answer 5

Digastric, mylohyoid

Question 6

What CN is responsible for controlling most of the intrinsic and extrinsic tongue muscles, and innervates tongue to squeeze bolus from the anterior part of the mouth to the posterior part of the mouth?

Answer 6

XII

Question 7

Is the pharyngeal phase voluntary or involuntary?

Answer 7

Involuntary

Question 8

How long does the pharyngeal phase last?

Answer 8

1 second

Question 9

When does the pharyngeal phase start?

Answer 9

Bolus contacts faucial arches?

Question 10

Swallowing phase when the velum closes, larynx raises and closes, breathing ceases, soft palate elevates, cricopharyngeus relaxes

Answer 10

Pharyngeal phase

Question 11

Crucial in keeping food/liquid out of nasal cavity

Answer 11

Soft palate (velum) closure

Question 12

How many pairs of faucial pillars do we have?

Answer 12

2

Question 13

What cranial nerves are involved in soft palate/velar movement?

Answer 13

V, X, XI

Question 14

What are some things you want to see when you view someone’s velum?

Answer 14

Pink/red color, symmetry

Question 15

Question 16

What happens when you say the consonants m, n?

Answer 16

Nasality, air goes out through nose

Question 17

What are the 3 valves that close to protect the airway from the bolus entering it?

Answer 17

Epiglottis, true vocal cords, false vocal cords

Question 18

Muscles that contract during the pharyngeal phase that raise the larynx under the closing epiglottis and further seal off the airway, protecting it from the bolus

Answer 18

Suprahyoid muscles

Question 19

What 2 cranial nerves control the superior, middle, and inferior pharyngeal constrictor and account for the squeezing sensation we feel in the throat during the pharyngeal swallow?

Answer 19

X, XI
