Fundamental frequency
lowest frequency of a complex sound
Max. phonational frequency range
Compete range of frequencies that an individual can produce
Alveoli
microscopic thinwalled structures within the lungs filled with air
bronchial tree
part of the respiratory sysytem that includes the trachea, bronchi, ad bronchioles
bronchioles
smalled subdivisions of the bronchial system
chest wall system
part of the respiratory system that includes the rib cage, abdomen, and diaphragm
Dead air
small amount of air not involved in oxygen-CO2 exchange
Expiratory reserve volume
amount of air that can be exhaled below Tidal Volume
Functional residual capacity
amount of air in the lungs and airways at the end of a normal quiet exhalation
Inspiratory reserve volume
amount of air that can be inhaled above tidal volume
intercostal muscles
made upj of internal and external sets sof muscles running between the ribs on both sides
parietal pleura
membrane lining the inner surface of the thoracic cavity
pleural linkage
the mechanism by which the lungs and thoracic cavity are linked together to function as a unit
residual volume
volume of air remaining in the lungs after a maximum exhalation that cannot be voluntarily expelled
resting expiratory level
state of equilibrium in the respiratory system when P(alv) = P(atmos)
Tidal Volume
Volume of air breathed in and out during a cycle of respiration
Total Lung capacity
total amount of air that the lungs are capable of holding
Vital Capacity
maximum amount of air that can be exhaled after a max inhalation
Amplitude Perturbation
cycle to cycle variability in VF amilitude (aka "Shimmer")
Aryepiglottic folds
Folds of connective tissue and muscle fibers running from the sides of the epiglottis to the apex of the arytenoid carilages
Arytenoid cartilage
paired cartilages of the larynx, forming a joint with the cricoid cartilage
Breathiness
Vocal quality that sounds aspirated due to air loss and turbulence at the glottis
cricoid cartilage
unpaired ring of cartilage forming the inferior portion f the larynx
cricothyroid muscle
(CT) intrinsic muscle of the larynx composed of the oblique and erect parts; elongates and tenses the VFs
Dysphonia
any kind of vocal dysfunction resulting in a deviant-sounding voice
Electroglottography
(EGG) Method of evaluating VF function based on the difference between electircal conductivity of tissue and air, aka laryngography
epiglottis
unpaired cartilage of the larynx involved in swallowing
Falsetto
a range of very high Fo with a thin, breathy quality; aka loft
False vocal Folds
like parallel and superior to true VFs; aka ventricular VFs
Frequency Perturbation
cycle to cycle variability in Vocal frequency; aka "Jitter"
Glottis
space between the true VFs
Harmonics to Noise ratio
meausre in dB of the ratio of harmonic energy to noise energy in voice
Hoarseness
vocal quality combining breathy plus rough characteristics
Hyoid bone
bone from which the larynx is suspended; also forms the attachment for the tongue
Hyperadduction
VFs adducted with excessive medial compression
Hypoadduction
VFs adducted with insufficient medial copmression
Infrahyoid Muscles
extrinsic muscles of the larynx; depress the larunx
Interarytenoid muscle
(IA) intrinsic muscle of the larynx composed of the transverse and oblique fibers; adducts the VFs
Lx Wave
Waveform generated by EGG, with time on the horizontal axis and voltage on the vertical axis
Modal Register
most commonly used register for normal conversational speech, encompassing the midrage of Fo
Myoelastic aerodynamic theory of phonation
Theory that explains VF vibration in terms of muscular, elastic recoil, and aerodymanic forces
posterior cricoarytenoid muscle
intrinsic muscle of the larynx; abducts the VFs
pulse register
range of very low Fo with a creaky voice quality; aka glottal fry, vocal fry, creaky voice
shimmer
cycle to cycle variability in amplitude of VF vibration; aka amplitude perturbation
spectral noise
additive noise in the glottal spectrum
suprahyoid muscles
extrinsic muscles of the larynx; elevate the larynx
Thyroarytenoid muscle
(TA) body of the Vocal FOlds
Thyroid Cartilage
largest cartilage of the larynx, unpaired
transglottal pressure
pressure difference across the VFs, between tracheal pressure and supraglottal pressure
Spasmodic dysphonia
voice disorder characterized by laryngeal spasms
Aphonia
complete absense of voice
dopamine
neurotransmitter deficient in PD
Botox Injection
proceedure in which minute amounts of botulinum toxin are injected into the VFs to alleviate spasms
Endotrachial intubation
process in which a breathing tube is inserted into the trachea through the larynx
laryngectomy
partial or total removal of the larynx, usually due to cancer
Fetal Cell transplantation
surgical treatment for PD, designed to replenish missing dopamine
