3

What is the upper oesophageal stricture?

A complete circle of skeletal muscle called the cricopharyngeus at the level of the C6 vertebrae, at the junction between the laryngopharynx and the oesophagus

4

Where does the midde constrictor of the pharynx originate?

The lesser and greater horns of the hyoid bone

5

Where does the inferior constrictor arise from?

Just behind the oblique line of the thyroid cartilidge and the side of the cricoid cartilidge

6

Where does the stylopharyngeus muscle originate and insert?

Styloid process

Pharynx, between the layers of the superior and middle constrictors

7

What is the nerve supply to the stylopharyngeus?

CN IX

8

Which muscle of the pharynx connects the eustachian tubes to the thyroid cartilidge?

Salpingopharyngeus

9

Which muscle connects the soft palate to the thyroid cartilidge?

Palatopharyngeus

10

Which nerve supplies the palatopharyngeus and the salpingopharyngeus?

CN X

11

What is the nerve supply of the longitudinal muscles of the pharynx?

CN IX and CN X

12

What is the function of the longitudinal muscles of the pharynx?

Elevate the larynx towards the epiglottis to reduce the size of the laryngeal inlet during swallowing, reducing chance of aspiration

13

What are the tonsils involved in Waldeyer's ring?

Pharyngeal tonsil

Tubal tonsils

Palate associated lymphoid tissue

Palantine tonsil

Lingual tonsil

14

Where are the pharyngeal tonsils located?

In the mucosa of the roof of the nasopharynx

15

Where are the tubal tonsils located?

In the mucosa of the eustachian tube opening

16

Where are the lingual tonsils located?

In the musosa of the posterior 1/3 of the tongue

17

At which level does the pharynx become the oesophagus?

C6 vertebral level
