Function of hyoid bone correct answers provides attachment for more than 20 muscles and
support for tongue
what is the thyroid cartilage tissue composition correct answers hyaline
how is the thyroid cartilage formed correct answers by fusion of two laminae, extending
posteriorly into the superior and inferior horns.
what forms most of the anterior and lateral walls of the larynx correct answers thyroid cartilage
what is the cricoid cartilage made of correct answers hyaline
what does the cricoid cartilage attach to and what does it form correct answers Attaches via
cricotracheal membrane to the 1st tracheal ring
Forms the lower portion of laryngeal framework
what is the epiglottis made of correct answers unpaired, elastic cartilage
what does the epiglottis attach to correct answers thyroid (bellow notch) by thyroepiglottic
ligament
hyoid bone by hyoepiglottic ligament
base of tongue by 1 median and 2 lateral glossoepiglottic ligaments
function of the epiglottis correct answers Keeps food from entering larynx (trapdoor)
what are the arytenoid cartilages anatomical features correct answers apex, muscular process,
vocal process
what are the arytenoid cartilages made of correct answers paired hyaline (mainly) pyramidal
shaped cartilage
what do the arytenoid cartilages articulate with correct answers cricoid (cricoarytenoid joint)
what are arytenoid cartilages attached by correct answers Attached by posterior and anterior
cricoarytenoid ligaments
what are the corniculate and cuneiform cartilages made of correct answers paired elastic
cartilages
where are corniculate cartilages located correct answers The corniculate cartilages sit on the
apexes of the arytenoid cartilages
, Attachment to aryepiglottic folds
where are cuneiform cartilages located correct answers The cuneiform cartilages are embedded
within the aryepiglottic folds
function of cuneiform cartilages correct answers May help keep airway open
Support for folds
function of cricothyroid joint correct answers Regulates longitudinal tension of vocal folds for
pitch change
function of cricoarytenoid joint correct answers Mediates abduction and adduction of the vocal
folds
diarthrodial
what type of joint is the cricothyroid joint correct answers pivot
what type of joint is the cricoarytenoid joint correct answers saddle (rocking and some gliding)
what are the extrinsic laryngeal membranes correct answers Hyothyroid membrane
Median hyothyroid ligaments
Lateral hyothyroid ligaments
Hyoepiglottic ligament
Cricotracheal membrane
list the intrinsic laryngeal membranes correct answers Cricothyroid ligaments
Anterior (medial) cricothyroid ligament (1)
Lateral cricothyroid membranes (conus elasticus) (2)
Quandrangular membrane
describe the mucous membrane correct answers one or more layers of epithelial cells overlying a
layer of loose connective tissue
Lines the entire larynxfrom the mouth and laryngeal cavity, to the trachea
Rich in mucous glands between the vocal and ventricular folds
Closely adherent to epiglottis, aryepiglottic folds and vocal folds; loose elsewhere
what makes up the entrance (auditus) correct answers Epiglottis
Aryepiglottic folds
Apexes of arytenoid cartilages
what are the landmarks of the larynx correct answers Aryepiglottic folds
Vestibular/Ventricle/ false folds
Vocal Folds
where are the aryepiglottic folds located correct answers Upper border of quadrangular
membrane
