Larynx Flashcards
these two structures of the neck are found at the same region the thyroid cartilage is found
pharynx and larynx
in the posterior part of larynx, what is in between corniculate cartilage around C4 and the cricoid cartilage around C6
arytenoid cartilage
what cartilage is connected to the vocal cord in anterior part of larynx and also connected to the corniculate cartilage in posterior part of larynx
arytenoid cartilage
2 parts of the arytenoid cartilage
vocal process
muscular process
what connects the vestibule of the epiglottis to the cricoid cartilage (2 folds)
vestibular fold
true vocal fold
what is in between the two folds of interior larynx
ventricle
spot between vestibular and vocal folds
rima
the mucous membrane of the vestibule (supraglottic) region
Quandragular membrane
mucous membrane of the infraglottic region
Conus elasticus
innervation to the supraglottic region
internal laryngeal n. (branch of CN X)
sensory to the infraglottic region
inferior laryngeal n. (branch of CN X)
motor innervation of the intrinsic muscles of larynx
CN X
only intrinsic muscle NOT innervated by inferior laryngeal n.
Cricothyroid
innervation to cricothyroid
external laryngeal n.
this muscle tenses the vocal ligament
Cricothyroid
this muscle is innervated by the inferior laryngeal n. and abducts the focal ligaments (gets air in to breathe)
Posterior Cricoarytenoid
this muscle is innervated by the inferior laryngeal n. and adducts the vocal ligaments
Lateral Cricoarytenoid
