recurrent laryngeal (a branch of the vagus)

2

the cricothyroid is the one intrinsic laryngeal muscle that isn't innervated by the recurrent laryngeal. Instead it's innervated by the...

external laryngeal nerve

3

the lateral cricoarytenoid muscle is located btwn... and does what?

btwn: cricoid and arytenoid.
contraction causes adduction of the vocal ligament

4

posterior cricoarytenoid muscles are innervated by...

the recurrent laryngeal nerve

5

posterior cricoarytenoid goes from where to where? does what?

goes from: cricoid ---> arytenoid cartilages.
it abducts the vocal ligament

6

the thyroarytenoid muscle is innervated by what?

recurrent laryngeal nerve

7

the thyroarytenoid muscle connects what? does what?

thyroid ---> arytenoid cartilage
does: loosening of the vocal ligament

8

vocalis muscle is innervated by...

recurrent laryngeal nerve

9

vocalis muscle connects what? does what?

connects: the most medial part of the thyoarytenoid muscle ---> thyroid cartilage/vocal ligament or arytenoid cartilage/vocal lig.
- it causes tension on segments of the vocal ligament

10

only muscle in the intrinsic laryngeal muscles not innervated by the recurrent laryngeal?

cricothyroid
