What are the laryngeal cartilages?

epiglottis, thyroid, arytenoid, cricoid

2

What is the rostral boundary of the larynx?

the epiglottis

3

What is the ventral and lateral boundary of the larynx?

thyroid cartilage

4

What is the dorsal boundary of the larynx?

arytenoid cartilage

5

What is the only paired cartilage in the larynx?

the arytenoid cartilage

6

Which laryngeal cartilage is a complete ring?

the cricoid cartilage

7

What part of the cricoid cartilage is the largest?

the dorsal side

8

What is located on the caudal aspect of the thyroid cartilage in the horse?

the caudal thyroid notch and the cricothyroid ligament

9

What does the cricothyroid ligament connect?

they thyroid and cricoid cartilages

10

Why is the cricothyroid ligament clinically relevant?

it is used to access the larynx during surgery

11

Where is the cuneiform process in the horse?

it is at the base of the epiglottis on both sides

12

What are the parts of the equine arytenoid cartilage?

corniculate process, muscular process, and vocal folds

13

What are the non-cartilagenous structures of the larynx in the horse and pig?

vestibular fold, vocal fold, lateral laryngeal ventricle, median laryngeal ventricle

14

Where is the lateral laryngeal ventricle located?

in between the vestibular and vocal folds

15

Where is the median laryngeal ventricle located?

rostral ventral to the lateral laryngeal ventricle

16

What are the non-cartilagenous structures of the larynx in the ruminant?

the vocal fold

17

What are the laryngeal muscles?

cricoarytenoideus dorsalis, cricothyroideus, thyroarytenoideus

18

What innervates the cricoarytenoideus dorsalis?

the caudal laryngeal nerve of the reccurent laryngeal of the vagus

19

What does the cricoarytnoideus dorsalis do?

abducts the arytenoids and vocal cords, and opens the epiglottis

20

What innervates the cricothyroideus?

the cranial laryngeal nerve of the vagus

21

What innervates the thyroarytenoideus?

the caudal laryngeal nerve of the recurrent laryngeal of the vagus

22

What innervates the pharyngeal constrictors?

the caudal laryngeal nerve of the recurrent laryngeal

23

What are the bones of the hyoid apparatus in the horse?

basihyoid, thyrohyoid, certaohyoid, epihyoid, stylohyoid, tympanohyoid

24

Which part of the hyoid apparatus is unpaired?

the basihyoid

25

Which part of the hyoid apparatus has a lingual process?

the basihyoid

26

What is the smallest part of the hyoid apparatus?

the epihyoid

27

What does the epihyoid fuse with?

the stylohyoid

28

What is the largest bone of the hyoid apparatus?

the stylohyoid

29

What is the tympanohyoid made up of?

hyaline cartilage

30

Where is the tympanohyoid located?

where the hyoid apparatus meets the skull
