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