Windpipe, connects lungs to the larynx

Question 2

Diaphragm

Answer 2

Major muscle of inspiration

Question 3

Intercostal muscles

Answer 3

Muscles of the rib cage that facilitate expiration

Question 4

Glottis

Answer 4

The space between the vocal folds

Question 5

Anterior commissure

Answer 5

Anterior juncture of the true vocal folds

Question 6

Posterior commissure

Answer 6

Posterior junction of the true vocal folds

Question 7

Supraglottic area

Answer 7

Area above the true vocal folds

Question 8

Subglottic area

Answer 8

Area below the true vocal folds

Question 9

Abduction

Answer 9

Open; away from midline

Question 10

Adduction

Answer 10

Closed; toward midline

Question 11

Thyroid cartilage

Answer 11

Largest cartilage in the larynx. Fused thyroid plates form thyroid notch (Adam’s apple)

Question 12

Cricoid cartilage

Answer 12

Cartilage found below the thyroid cartilage and above the trachea

Question 13

Arytenoid cartilages

Answer 13

Pair of pyramid shaped cartilages that serve as posterior attachment of the vocal folds. Movement is responsible for abduction and adduction of the vocal folds

Question 14

Muscular process

Answer 14

The extensions where the posterior and lateral cricoarytenoid muscles attach

Question 15

Vocal process

Answer 15

The anterior and medial extension of the arytenoid cartilages, where the posterior vocal fold ligament attaches via a tendon-like structure called the macula flava

Question 16

Epiglottis

Answer 16

The superior part of the larynx, located posterior to the hyoid bone and base of the tongue

Question 17

Corniculate cartilages

Answer 17

Paired elastic cartilages mounted on top of the arytenoid cartilages

Question 18

Cuneiform cartilages

Answer 18

Paired elastic cartilages embedded in the aryepiglottic muscle/fold

Question 19

Cricothyroid joint

Answer 19

A synovial joint formed between the cricoid and arytenoid cartilages

Question 20

Aryepiglottic folds

Answer 20

The false cords

Question 21

Laryngeal vestibule

Answer 21

The space between the laryngeal side of the epiglottis, aryepiglottic folds, vocal folds, and arytenoids

Question 22

Laryngeal ventricle

Answer 22

Space between the ventricular folds and the true vocal folds

Question 23

Vallecula

Answer 23

Space between tongue and epiglottis

Question 24

Thyroarytenoid muscle

Answer 24

Muscle within the vocal folds

Question 25

Posterior cricoarytenoid muscle (PCA)

Answer 25

An intrinsic laryngeal muscle that when contracted abducts the vocal folds

Question 26

Lateral cricoarytenoid muscle (LCA)

Answer 26

An intrinsic laryngeal muscle that serves to adduct the vocal folds

Question 27

Cricothyroid muscle

Answer 27

Intrinsic laryngeal muscle primarily increasing vocal fold length and the elevation of vocal pitch

Question 28

Interarytenoid muscles

Answer 28

Muscles connecting the arytenoids that adduct the vocal folds when contracted

Question 29

Recurrent laryngeal nerves

Answer 29

Branch of vagus nerve that innervates the intrinsic laryngeal muscles

Question 30

Suprahyoid muscles

Answer 30

Elevate the hyoid bone and larynx (digastric, anterior and posterior bellies, mylohyoid, geniohyoid, stylohyoid)

Question 31

Infrahyoid muscles

Answer 31

Primarily depress the hyoid and larynx (sternohyoid, sternothyroid, omohyoid, thyrohyoid)
