309 Larnyx Test
Intrinsic and Extrinsic muscles

Questions and Answers

1.

Muscles with both attachments inside the larynx -change status of glottis: adduct, abduct, tense relax -always acts in pairs -adjust glottal closure through - medial compression, longitudinal tension
2.

Intrinsic muscle that tenses, relaxes and ADDUCTS -main mass of the vocal folds -consists of two muscle masses
3.

Thyroarytenoid muscle that -originates at the posterior border of angle of the thyroid -inserts into the VOCAL process and lateral surface of arytenoids
4.

Thyroarytenoid muscle that -originates at the thyroid lamina lateral to the vocalis -inserts anterolateral surface and MUSCULAR process of arytenoids *Regulator of muscle tension ---when not opposedby other muscles, shortens the vocal folds, causing less tension ---may assist in close vocal folds by drawing muscular processes forward ---with other muscles active tenses vocal folds
5.

Intrinsic muscle that is a tensor, fan shaped muscle with two parts
6.

Cricothyroid muscle that is lateral -inserts into the inferior horn of the thyroid -function is slides thyroid slightly anterior
7.

Cricothyroid muscle that in anterior -inserts into the lower margin of thyroid lamina -function is to reduce the distance between the cricoids and causing the vocal folds to lengthen and tense
8.

Intrinsic muscle that is the ONLY abductor, broad fan-shaped muscle -originates posterior aspect of quadrate lamina -inserts into the muscular process of arytenoids -function rotates muscular processes laterallly, opening vocal folds
9.

Intrinsic muscle that adducts, fan shaped located deep to the thyroid cartilage -originates at the upper border of anterolateral arch of cricoid -inserts muscular process of arytenoids -function rotates muscular process medially to close the vocal folds
10.

Intrinsic muscle that has two parts on the posterior surface of arytenoids BOTH functions are to slide arytenoids medially
11.

An interarytenoid that is more superficial -origin is posterior surface of one arytenoid -inserts near apex of opposite arytenoid
12.

Interarytenoid that is deeper than oblique -origin lateral margin and posterior surface of each arytenoid -lateral margin and posterior surface of other arytenoids
13.

Muscles with one attachment outside of the larynx -support the larynx inthe neck -may aid in production of extreme or high and low frequencies
14.

Extrinsic muscles that are all laryngeal elevators and one attachment is above the hyoid bone. *All have attachments on the skull
15.

Suprahyoid muscle that is paired and divided into two bellies BOTH elevate the hyoid bone
16.

Digastric muscle that originates at the lower border of mandible near midline and attaches to intermediate tendon which attaches to the lesser horn of the hyoid bone
17.

Digastric muscle that originates onthe mastoid process of the temporal bone and inserts into the intermediate tendon
18.

Long and slender suprahyoid muscle that originates at the styloid process of the temporal bone that draws hyoid bone up and back
19.

Thin sheet of muscle that forms the floor of the mouth (suprahyoid) -originates on the inner surface of mandible from mental symphysis to last molar -inserts anterior fibers from each side meed at midline raphe, posterior fibers insert directly into the hyoid bone -function elevates the hyoid and base of the tongue
20.

Suprahyoid muscle that is paried cylindrical muscle located just above mylohyoid -originates onthe lower part of mental symphysis -inserts to the body of the hyoid -function with mandible fixed, raises hyoid bone up and forward
21.

Extrinsic muscle that are laryngeal depressors has one attachment below the hyoid bone
22.

Infrahyoid muscle that is a flat sheet lying on the anterior surface of the neck -originates posterior surface of manubrium and medial end of clavicle -inserts body of the hyoid -function depress hyoid bone
23.

Infrahyoid muscle that is long, narrow, and two bellied
24.

Omohyoid that originates on the upper border of scapula and inserts into the intermediate tendon (depresses hyoid bone)
25.

Omohyoid that originates at the intermediate tendon and inserts into the greater horn of the hyoid (depresses hyoid bone)
26.

Infrahyoid muscle that is logn slender in the anterior of the neck -originates at the manubrium and first costal cartilage -inserts into the thyroid lamina function: stabilize larynx, may draw hyoid down
27.

Infrahyoid muscle that is superior extension of the sternothyroid -originates at the thyroid lamina -inserts into the greater horn of the hyoid bone function: decreases distance between the thyroid and hyoid
