PPT 4 Phonation Anatomy 1 Flashcards
Phonation Anatomy
produced without use of vocal folds
voiceless sounds
produced by action of vocal folds
voiced sounds
vibrating vocal folds within the larynx
phonation
what provides the energy source for phonation
air from the lungs
space between the vocal folds
glottis
most important laryngeal space for speech
glottis
defined why the variable sphincter that allows voicing
glottis
below the vocal folds
sub glottal
primary function of the phonatory system
protection of the vocal folds through throat clearing
secondary function of the phonatory system
phonation
process of adducting folds to begin process of phoning
attack
abduction of vocal folds
termination
the larynx is what type of structure
musculo-cartilaginous
located at the top of the first ring of the trachea
larynx
the larynx is adjacent to where
cervical vertebrae 4 through 6
average length of larynx in adult males
44 mm
average length of larynx in adult females
36 mm
what is the only bone in the body that isn’t articulated with any other bone
hyoid bone
list the three unpaired cartilages
thyroid, cricoid, and epiglottis
list the three paired cartilages
arytenoid, corniculate, and cuneiform
the left and right lamina make up the
thyroid cartilage
the left and right lamina meet at the
laryngeal prominence
we can see the oblique line , an attachment point for various other muscles, from what view
lateral
the hyoid bone and thyroid cartilage are held together by
thyroid membrane
where the arytenoid cartilage sits
superior facet
where the inferior forms of the thyroid articulate
lateral facet
name the two joints of the larynx
cricoidarytenoid and cricothyroid
the movement of the cricothyroid joint
anterior tilt (forward and back)
the movements of the cricoarytenoid joint
glide (opening and closing) and rotating
the cricoarytenoid joint helps to _ the vocal folds
elongate
which process is closer to the thyroid
vocal process.
which process is the posterior part of the vocal folds
muscular process
where the movement of the vocal folds begins
cartilaginous margin
when the vocal folds glide and rotate what is set into motion
membranous margin
short and skinny vocal folds with result in a voice that is _ in pitch
higher
typical length of vocal folds in adult males
17-21 mm
typical length of vocal folds in adult females
11-15 mm
t/f vocal fold abduction requires both folds pulling away from one another
false
the cricoarytenoid joint is a _ joint
synovial
the three movements of the cricoarytenoid joint help to
bring the vocal folds closer together
closes over the larynx and airway when swallowing
epiglottis
used to visualize the vocal folds
laryngeal mirror
the five layers of the vocal folds
squamous epithelium, superficial lamina propria, intermediate lamina propria, deep lamina propria, thyroaryenoid muscle thyrovocalis part, thyroarytenoid muscle thyromuscularis part
The muscular process serves as an articulation point for the
thyromuscularis
the vocal process serves as an articulation point for the
thyrovocalis
space between aditus and the ventricular folds
vestibule
middle space of the larynx between the ventricular and the vocal folds
middle vestibule
taking out a part or the whole larynx
laryngectomy
Consequences of laryngectomy
swallowing difficulties, speaking difficulties
