Anatomy
These are the 5 main intrinsic muscles of the larynx
What are the thyroarytenoid, posterior cricoarytenoid, lateral cricoarytenoid, arytenoids (transverse and oblique), cricothyroid?
These membranes are extrinsic
What are the thyrohyoid membrane, hyoepiglottic ligament, and cricotracheal membrane?
There are this many muscles in the larynx (name at least 2)
What are 5?
Posterior and lateral cricoarytenoid
Transverse and oblique arytenoid
Cricothyroid
Thyromuscularis
Thyrovocalis
These make up the structure of the larynx
What are the hyoid bone, thyroid cartilage, arytenoid cartilages, corniculate cartilages, and cricoid cartliages?
The entryway to the larynx
What is the vestibule?
These are the sites of vocal fold attachment
Where are anteriorly to the thyroid cartilage (below the thyroid notch) and posteriorly to the arytenoid cartilages?
This cartilage containing hyaline prevents instability of the trachea and contains muscles that elongate the vocal folds
What is the cricoid cartilage?
This muscle pulls the arytenoids out laterally
What is the posterior cricoarytenoid?
This sits atop the trachea, inferior to thyroid cartilage
What is the cricoid cartilage?
The space between the vocal folds
What is the glottis?
This allows for adduction/abduction of the vocal folds in a rocking and gliding motion
What is the Cricoarytenoid?
These are intrinsic membranes
What are the quadrangular membrane and conus elasticus?
These are ADDuctors muscles
What are the lateral cricoarytenoid, oblique arytenoid, and transverse arytenoid?
Two of this kind of muscle aids in the shortening and thickening of the folds
What are thyroarytenoids?
This space is between the true and false vocal folds and helps keep the the vocal folds moist
What is the ventricle?
This allows for tensing and relaxing of the vocal folds
What is the Cricothyroid?
These are triangular folds of mucous membrane of the larynx
What are the aryepiglottic folds?
The vibratory patterns of the VF are set by which two types of muscles
What are tensor and relaxer muscles?
This is an ABductor muscle
What is the posterior cricoarytenoid?
The glottis is also known as
What is the Rima glottidis?
This structure helps protect the airway during swallowing
What is the epiglottis?
This cartilage’s primary function is to protect the airway during swallowing
What is epiglottis?
This muscle pulls the arytenoids together
What is the transverse arytenoid?
These are tensor muscles
What are cricothyroid muscles, pars rectus, and pars oblique?
This thin sheet that forms the muscular floor of the oral cavity
What is the Mylohyoid?
