Flashcards in 10.2 The Pharynx and Disorders of the Pharynx Deck (34):
1

Where is the nasopharynx?

Between base of skull and start of soft palate

2

What epithelium is found in the nasopharynx?

Pseudostratified ciliated columnar epithelium

3

What does the nasopharynx contain?

Adenoids and eustachian tube orifice

4

Where is the oropharynx?

Behind oral cavity. From soft palate to superior border of epiglottis

5

What epithelium is found in the oropharynx?

Stratifies squamous epithelium

6

What does the oropharynx contain?

Palatine tonsils

7

What are the palatine tonsils?

Lymphoid tissue covered in squamous epithelium and encapsulated in large crypts.

8

Where are the palatine tonsils found within the oropharynx?

Between the palatoglossal arch (anterior) and palatopharyngeal (posterior) arch

9

What are the 4 types of lymph tissue which make up Waldeyer's ring?

Pharyngeal
Tubal
Palatine
Lingual

10

Where is the epiglottis?

Between superior border of epiglottis and inferior border of cricoid cartilage

11

What type of epithelia is found in the laryngopharynx?

Stratified squamous epithelium

12

What does the laryngopharynx open up into posteriorly?

Oesophagus

13

What does the laryngopharynx open up into anteriorly?

Trachea

14

What nerve provides sensory innervation to the nasopharynx?

Maxillary nerve

15

What nerve provides sensory innervation to the oropharynx?

Glossophayngeal nerve

16

What nerve provides sensory innervation to the laryngopharynx?

Vagus nerve

17

Which vessels supply the pharynx?

Ascending pharyngeal
Lingual
Facial
Maxillary

18

What vessels drain the pharynx?

Pharyngeal venous plexus

19

Name the 3 circular muscles around the pharynx

Superior constrictor
Middle constrictor
Inferior constrictor

20

What nerve innervates the constrictor muscles of the pharynx?

Vagus

21

Where do the constrictor muscles attach to posteriorly?

Anterior raphe

22

What are the 2 parts of the inferior constrictor?

Thyropharyngeus
Cricopharyngeus

23

Name the 3 longitudinal muscles of the pharynx

Stylopharyngeus
Palatopharyngeus
Salpingopharyngeus

24

Where is the pathway of the stylopharyngeus muscle?

Styloid process to pharynx

25

Where is the pathway of the palatopharyngeus muscle?

Hard palate to pharynx

26

Where is the pathway of the salpingopharyngeus muscle?

Eustachian tube to pharynx

27

Which nerve innervates the stylopharyngeus muscle?

Glossophayngeal nerve

28

Which nerve innervates the salpingopharyngeus and palatopharyngeus muscle?

Vagus nerve

29

How is the pharynx involved with swallowing?

Food pushed from oral cavity to oropharynx
Tongue and suprahyoid muscles pull hyoid and larynx up
Soft palate elevates and nasopharynx is sealed off
Superior constrictors contract
Food bolus passes into laryngopharynx using middle and inferior constricters
Cricopharyngeus relaxes

30

What are the effects on enlarged adenoids?

Mouth breathing
Hyponasal speech
Breastfeeding difficulty
Snoring
Otitis media

31

What is obstructive sleep apnoea?

Partial airway constriction when sleeping. Results in snoring and daytime tiredness

32

What is an adenoidectomy?

Removal of the adenoids

33

What is a tonsilectomy?

Removal of pallatine tonsils

34

What is a pharyngeal pouch?

Posterior herniation of the pharyngeal mucosa through the gap between the 2 parts of the inferior constrictor muscle. Incoordination of swallowing, cricopharyngea spasms and bad breath
