Phonation: Module 9

Unpaired Cartilage

thyroid, epiglottis, criciod

paired cartilage

arytenoid, circulate, cuniform

which cartilage contains superior and inferior horns

thyroid cartilage

a leaf shaped cartilage ring attached to the thyroid cartilage and the hyoid bone

epiglottis

the true vocal folds attach to the

antieror commisure

which cartilage is located immediately superior to the trachea

cricoid cartilage

form a joint with the cricoid cartilage, allow vocal folds to adduct and abduct

arytenoid cartilages

the arch and quadrate laminate form part of which cartilage

cricoid cartilage

which cartilages are located on the apex of each arytenoid cartilage

corniculate

the cricothyriod joints are

synovial

leaf shaped structure attached to the hyoid and thyroid cartilage

epiglottis

joint involved in vocal fold adduction and abduction

cricoarytenoid joint

posterior portion of the cricoid cartilage

quadrate lamina

embedded within the aryepiglottic folds

cuneiform cartilage

on the thyroid laminate where extrinsic muscles attach

oblique line

projects anteriorly from the base of each arytenoid cartilage

vocal process

joint involved in pitch regulation

cricothyroid joint

extensions of the thyroid cartilage attached to the hyoid

superior horns

from the sides of the hyoid bone

major horns

projects posteroleterally from the base of the arytenoid cartilage

muscular process

point at which the vocal folds attach anteriorly

anterior commisure

located on the apex of each arytenoid cartilage

corniculate cartilage

the larynx is suspended from the

hyoid bone

true vocal folds attach to the thyroid cartilage at the

anterior commissure

the posterior portion of the cricoid cartilage is called the

quadrate lamina

the ___ membrane attaches the cricoid cartilage to the thyroid cartilage

cricothyroid

the ____ is the narrowest part of the epiglottis

petiole

the ____ of the arytenoids projects anteriorly and attaches to the vocal folds

vocal process

front portion of the cricoid cartilage

arch

most inferior of the laryngeal cartilages

cricoid

cartilage that forms the Adams apple

thyroid

folds: arytenoids to epiglottis

aryepiglottis

narrowest portion of the epiglottis

petiole

these cartilages sit on top of the arytenoids

corniculates

contain the vocal and muscular processes

arytenoid

soem people have these small cartilages within the thyroid membrane

triticeal

cartilage embedded in the aryepiglottic fold

cuneiform

covers the larynx during swallowing

epiglottis

has a body, major horns, and minor horns

hyoid

membrane that connects the cricoid cartilage to the trachea

cricotracheal

membrane that connects the thyroid to the hyoid

thyrohyoid membrane

The vestibular folds are located superior to the

true vocal folds

the __________ bone is an independent bone that does not contact any other bone

hyoid

From the outer most, the vocal folds layers are epithelium, superficial layer of the lamina propria, _________________, ________________, and thyrovocalis muscle.

intermediate layer of the lamina propria, deep layer of the lamina propria

The only muscle that abduct the vocal folds is _______

posterior cricoarytenoid muscle

Thyrovocalis muscle is also called

medial thyroarytenoid

Extrinsic muscles contribute to stabilize and adjust the ____ to facilitate proper actions of the intrinsic muscles.

laryngeal positionlarynx

airway protection, fixation of the thorax and abdomen, phonation

are primary functions of the larynx.

between the true vocal folds

glottis

fine motor control of vocal folds

intrinsic muscless

stabilize and adjust laryngeal position

extrinsic muscles

move arytenoids, change vocal fold position, adducting and abducting

cricoarytenoid muscle

changes vocal fold length and tension, regulates pitch, changes pitch

cricothyroid

on thyroid lamina that provides attachment for muscles

oblique line

Intrinsic muscles located

within larynx

Extrinsic muscles located

outside larynx

sole abductor (airway)

PCA

fine control of vocal fold tension and stiffness

vocalas

Supra (up)

digjstic, mylohyoid, geneohyoi, stylohyoid

Infra (down)

sternohyoid, omhyoid, thyrohyoid, sternothyroid
