Phonotory System Cartilages Intrinsic Muscles Extrinsic Muscles Miscellaneous
100
What is the larynx
This structure houses the vocal folds
100
What is the thyroid
This is the largest laryngeal cartilage
100
What is thyroarytenoid
This is another name for the vocalis muscle
100
What suprahyoids and infrahyoids
These are extrinsic muscle subgroups
100
What is the adducted position
The vocal folds are in this position for phonation
200
What are the vocal folds
The vocalis muscle is the main muscle mass of this structure
200
What is the epiglottis
This is a flexible elastic cartilage that sits superiorly to the thryoid
200
What is the posterior cricoarytenoid
This is the only intrinsic, abductor laryngeal muscle
200
What is laryngeal elevator
This is the primary function of suprahyoids
200
What is the vibration of the vocal folds
This create the pitch of voice
300
What is the synovial joint
This type of joint is highly mobile
300
What are the corniculates
These are elastic conical-shaped cartilages
300
What are abduction, adduction, tension
These are the 3 main functions of intrinsic laryngeal muscles
300
What is the sternohyoid
This muscle extends from the chest bone to the "floating bone"
300
What is Bernoulli's principle
This principle explains the inverse relationship between air pressure and velocity
400
What is the cricothryoid or cricoarytenoid
This is one joint associated with the larynx
400
What are the arytenoids
The posterior portion of the vocalis muscles attaches to the vocal processes of these cartilages
400
What are transverse and oblique
These are the 2 parts of the interarytenoids
400
What is the geniohyoid
This muscle is deeper than the mylohyoid and runs from the hyoid to the chin
400
What are the true vocal folds, false (ventricular)folds, and aryepiglottic folds
These are the 3 sets of folds found within the larynx
500
What is 13-18 mm....males have a range of 17-25 mm
This is the length range of female's vocal folds
500
What is antero-inferior movement
The cricothyroid joint allows for this movement of the thyroid
500
What is the cricothryoid
This muscle is a major contributor to increasing vocal fold length and tension
500
What are CNs V, VII, and XII
These are the 3 cranial nerves involved with innervating the extrinsic laryngeal muscles
500
What are mass, elasticity, and length
These are 3 physical factors that affect the vibration of the vocals folds
