how is phonation related to respiration

respiration is the source of energy for speech

production of voice due to the cyclic opening and closing of the vocal folds

2 principles that allow the vocal folds to open and close

1) muscle tension (myoelasticity) 2) aerodynamics

characteristics of the larynx (4)

1) funnel shaped made of: 2) cartilage 3)connective tissue 4) muscle

anatomical position/orientation of larynx (2)

1) anterior/ventral to esophagus and spine 2)superior to trachea

primary function of larynx (biological or speech function)

biological, protects/prevents entry of foreign objects past larynx into trachea, then lungs

4 biological functions of the larynx

1) coughing 2)throat clearing 3)abdominal fixation 4)reflexive actions

coughing physiology + purpose

1) deep inhale, VFs open widely 2) elevation of larynx 3) tense/ tightly close vocal folds 4)subglottal air pressure blows apart vocal folds purpose: expel foreign object

throat clearing physiology + purpose

1) deep inhale, VFs open widely 2) elevation of larynx 3)tense/tightly close VFs 4)positive subglottal pressure blows VFs apart purpose- expel mucus

similarity and difference between cough/throat clear

similarity: excessiveness/repetition causes damage to voice difference: cough is more violent,

abdominal fixation (physiology + purpose)

1) deep inhale 2) tense/ tightly close VFs purpose- capture air in thorax to stabilize torso -good for weight lifting

reflexive actions physiology + purpose

dilation/opening of larynx -mostly involuntary purpose

which 2 nonspeech functions can be used in therapy to get initial phonation

1) coughing 2) abdominal fixation

anatomical position/orientation of true and false vocal folds

the false vocal folds are superior to the vocal folds

5 layers of the vocal folds (3)

1) squamous epithelium (w/ basement membrane) 2,3,4) lamina propria (3 connective tissue layers) 5) muscle

layers of the lamina propria

layers 2,3, and 4 of the vocal folds (superficial to deep) 2) elastin (cover) 3) elastin (body) 4) collagen (density + tensile strength)

what does layer 5 of the vocal folds consist of (2)

1)thyrovocalis 2)thyromuscularis muscles

vocal fold movement (2, caused by what)

1)adduction 2)abduction -both caused by muscular action

closing of vocal folds (used in phonation + other biological functions)

opening of vocal folds (used in breathing)

Question	Answer
how is phonation related to respiration	respiration is the source of energy for speech
what is phonation	production of voice due to the cyclic opening and closing of the vocal folds
2 principles that allow the vocal folds to open and close	1) muscle tension (myoelasticity) 2) aerodynamics
main structure for phonation	larynx
characteristics of the larynx (4)	1) funnel shaped made of: 2) cartilage 3)connective tissue 4) muscle
anatomical position/orientation of larynx (2)	1) anterior/ventral to esophagus and spine 2)superior to trachea
primary function of larynx (biological or speech function)	biological, protects/prevents entry of foreign objects past larynx into trachea, then lungs
4 biological functions of the larynx	1) coughing 2)throat clearing 3)abdominal fixation 4)reflexive actions
coughing physiology + purpose	1) deep inhale, VFs open widely 2) elevation of larynx 3) tense/ tightly close vocal folds 4)subglottal air pressure blows apart vocal folds purpose: expel foreign object
throat clearing physiology + purpose	1) deep inhale, VFs open widely 2) elevation of larynx 3)tense/tightly close VFs 4)positive subglottal pressure blows VFs apart purpose- expel mucus
similarity and difference between cough/throat clear	similarity: excessiveness/repetition causes damage to voice difference: cough is more violent,
abdominal fixation (physiology + purpose)	1) deep inhale 2) tense/ tightly close VFs purpose- capture air in thorax to stabilize torso -good for weight lifting
reflexive actions physiology + purpose	dilation/opening of larynx -mostly involuntary purpose
which 2 nonspeech functions can be used in therapy to get initial phonation	1) coughing 2) abdominal fixation
secondary function of the larynx	-phonation (not biological)
glottis	space between vocal folds
what are the vocal folds also called	the TRUE vocal folds
what are the false vocal folds also called	vestibular/ventricular folds
anatomical position/orientation of true and false vocal folds	the false vocal folds are superior to the vocal folds
5 layers of the vocal folds (3)	1) squamous epithelium (w/ basement membrane) 2,3,4) lamina propria (3 connective tissue layers) 5) muscle
layers of the lamina propria	layers 2,3, and 4 of the vocal folds (superficial to deep) 2) elastin (cover) 3) elastin (body) 4) collagen (density + tensile strength)

vocal fold movement (2, caused by what)	1)adduction 2)abduction -both caused by muscular action
adduction	closing of vocal folds (used in phonation + other biological functions)
abduction	opening of vocal folds (used in breathing)
