1

Within the piriform recess you will find 2 nerves. What are they?

internal branch of the superior laryngeal nerve and the inferior laryngeal nerve (a continuation of the recurrent laryngeal nerve which changes its name at the cricothyroid joint)

2

What muscle passes from the arch of the cricoid cartilage (anteriorly) to the muscular process of the arytenoid cartilage (posteriorly)?

lateral cricoarytenoid muscle

3

the opening of the laryngeal cavity formed by the superior margin of the EPIGLOTTIS and the ARYEPIGLOTTIC FOLDS

aditus

4

Superior to the lateral cricoarytenoid muscle the ____ muscle attaches to the interior of the thyroid cartilage near its angle and to the arytenoid cartilage posteriorly.

thyroarytenoid muscle

5

the "true vocal fold" as it contains the vocal cord within the ligament

vocal fold

6

Through the mucosa you will find the lamina of the cricoid cartilage. Superior and lateral to the lamina you will see the ___ ___.

piriform recess

7

formed by two LAMINAE, joined anteriorly to form the angle and its LARYNGEAL PROMINENCE

thyroid cartilage

8

shaped like a ring with a broad, flat LAMINA that is posterior and an ARCH that is anterior

cricoid cartilage

9

the "false vocal fold" more superior of the paired folds

vestibular fold

10

suprahyoid muscles

geniohyoid, mylohyoid, stylohyoid, digastric

11

a ceruved, vertical recess of teh ventricle

saccule of the larynx

intrinsic

extrinsic (supra- and infrahyoid)

13

the space between the vocal folds and trachea

infraglottic cavity

14

the large part of the cavity between the aditus and the vestibular folds

vestibule of the larynx

15

infrahyoid muscles

sternohyoid, omohyoid, sternothyroid, thyrohyoid

16

What two muscles are found superior to the posterior cricoarytenoid muscle?

transverse and oblique arytenoid muscles of course

17

The vocal folds + the rima glottidis = ?

small bump more posterior and medial that its wedge-shaped cousin the cuneiform cartilage

corniculate tubercle

space between the vestibular and vocal folds (part of the transglottic space)

ventricle of the larynx

The interval (gap) between the left and right vocal folds is called the ____ _____.

rima glottidis

26

connects the superior border of the thyroid cartilage with the hyoid bone
