Question 1

Base the larynx sits on

Answer 1

Cricoid cartilage

Question 2

Attachment for laryngeal muscles and protect VF, sit on top of cricoid

Answer 2

Thyroid cartilage

Question 3

True vocal folds ligament attaches to

Answer 3

Vocal processes of arytenoids

Question 4

Cricoid -> thyroid, rocking/sliding of thyroid on cricoid to elongate VF (increase pitch)

Answer 4

Cricothyroid joint

Question 5

Cricoid -> arytenoid, rocking and lateral movement to determine glottal opening

Answer 5

Cricoarytenoid joint

Question 6

General functions of intrinsic laryngeal muscles

Answer 6

Change length of VF, change glottal opening, medial compression of VF

Question 7

Inferior horns of thyroid -> anterior cricoid, lengthen/tense VF, decrease space between cricoid & thyroid

Answer 7

Cricothyroid muscle (CT)

Question 8

Shorten VF

Answer 8

Thyroarytenoid muscle (TA)

Question 9

Attach vocal process -> internal thyroid notch, adduct front and tense VF

Answer 9

Thyrovocalis (medial TA)

Question 10

Attach muscular process -> thyroid notch, relax VF

Answer 10

Thyromuscularis (lateral TA)

Question 11

Attach muscular process -> lateral cricoid, adduct VF by bringing arytenoid to midline, regulate medial compression

Answer 11

Lateral cricoarytenoid muscle (LCA)

Question 12

Adduct VF by bringing arytenoids -> midline

Answer 12

Interarytenoid muscle (IA)

Question 13

Attach horizontally around arytenoids, pull bases together to adduct

Answer 13

Transverse IA (TIA)

Question 14

Attach diagonal from one muscular process -> apex of other, superficial to TIA, pull tips together to adduct, close posterior glottis

Answer 14

Oblique IA

Question 15

Attach muscular process -> lateral cricoid, abduct VF by opening and elevating vocal processes, stabilze arytenoids, antagonized by LCA/IA

Answer 15

Posterior cricoarytenoid muscle (PCA)
