All about the Vocal Cords
any space BELOW the vocal cords is called...
subglottal space
this is the only floating bone in our body
Hyoid
the largest cartilage in the larynx is called?
thyroid cartilage
Laryngeal muscles are divided in 2 groups... which ones are they?
Intrinsic = adjust vocal mechanism
Extrinsic = elevate/depress larynx
describe what "pitch" is
how high or low a voice sounds
this is the product of the vibration of the vocal cords
voice or phonation
this is the MOST important laryngeal space for speech
Glottis
List the different cartilages
cricoid, thyroid, and epiglottis = unpaired
arytenoid, corniculate, and cuneiform = paired
What are the 5 categories of the Intrinsic Muscles?
adductors, abductors, tensors, relaxers, auxiliary musculature
Describe vocal intensity
The increase of subglottal pressure to produce a louder voice
what's the name of the deepest layer of the vocal cords?
Vocalis
what is the other name we can use for "false vocal cords"
Ventricular folds
These are THE most important cartilages of the larynx
Arytenoid and Corniculate Cartilage
Explain the difference between INFRAhyoid and SUPRAhyoid muscles
Infrahyoid = muscles below the hyoid bone and Suprahyoid - muscles above the hyoid bone
the most important function of the larynx is to...
protect the airway!
the name of the space between the vocal cords is called?
Glottis
what is the term used for "laryngeal entrance"?
Aditus Laryngis
This cartilage is very important during swallowing. It protects the airway.
Epiglottis
What's the job of the laryngeal elevators?
The muscles elevate the hyoid and the larynx
Give me 3 examples of vocal registers
falsetto, glottal fry, modal, whistle register, breathy/pressed phonation, whispering
List the 5 layers of the Vocal Cords
epithelium, superior lamina propia, intermediate lamina propia, deep lamina propia and vocalis
Thi sis the first cavity of the larynx
Vestibule
Why are the arytenoid and corniculate cartilages important in phonation?
They allow the onset and offset for voicing
What's the job of the laryngeal depressors?
Depress the larynx
In regards to phonation, why is the Bernoulli Effect important?
It helps explain how the vocal folds come back together during vibration.
(remember the hourglass movement)
