normal voice Flashcards
what are the subsystems of voice
breathing, phonation, resonace and articulation
what are the characteristics of inhalation
ribcage expands
diaphragm lowers
low pressure causes lungs to draw in air
what are the characteristics of exhalation
elastic recoil
diaphragm relaxes
high pressure - lungs puch air out
what is the glottis
space between vocal folds
what makes a person’s voice unique
resonace
whats the difference between abducted and adducted
Abducted - vocal cords apart
Adducted - vocal cords together
what is resonance
The amplification, richness, and quality of your voice
what muscles are involved in vocal adduction
Thyroarytenoid muscle
Lateral cricoarytenoid muscle (R & L muscles)
Inter-arytenoid muscle (transverse and oblique)
what is the thyroarytenoid muscle attached to
thyroid and arytenoid cartilage
what is the function of the thyroarytenoid muscle
shortens and relaxes vocal ligament
what is the Lateral cricoarytenoid muscle attached to
cricoid and arytenoid cartilage
what is the function of the Lateral cricoarytenoid muscle
closes vocal cords
what is the inter-arytenoid muscle attached to
right and left arytenoid cartilages
what is the function of the inter-arytenoid muscle
closes inlet of larynx
what is the function of the posterior cricoarytenoid muscle
abduct vocal cords by moving arytenoid cartilages
what mucles are involoved with pitch and tension
vocalis muscle and cricothyroid muscle
what is the function of the vocalis muscle
Alters vocal fold tension/relaxation during speaking or singing
what is the function of the cricothyroid muscle
tilts the thyroid cartilage - increasing tension of vocal folds
what does the recurrent laryngeal nerve innervate
all muscles reponsble for voicing except the cricothyroid (pitching)
what is the cricothyrioid muscle innervated by
superior laryngeal nerve
what is the function of the vocal fold mucosa
jiggles over the stiffer lower layers, giving rise to the mucosal wave
what is part of the vocal fold mucosa
epithelium, basement membrane, Reinke’s space
how is the glottis affected by pitch
high pitch - narrow glottis
low pitch - wide glottis
what are the factors of voice modulation
Duration, Intensity, Loudness, Pitch, Tone
