Intro test 1 p2 Flashcards
Thoracic cavity ( Respiratory System)
“Thoracic cage: rib cage” Had 12 pairs of ribs
Respiratory system
Process of breathing, Inhale and exhale, Produces air under pressure which generates speech
Diaphragm ( respiratory system)
thick muscle shaped like a dome
Pulmonary system (respiratory system)
cone shaped lung, includes upper and lower airways
Upper airway (respiratory system)
includes mouth nose and upper portions of throat
Lower airway (respiratory system)
includes the tracea
Respiratory stucture
Vocal cords sit right on top of trachea
phonate
To phonate is to produce voice
Phonotation
sub-glottal Air pressure, Bernoulli effect, myoelastic aerodynamic theory.
Variations in patterns of movement (Phonatory system)
Pitch- how high
Loudness how loud
larynx
a valve that opens and closes, sets molecules from breath stream into vibration ( vocal folds), sound production when phonation occurs.
when silenced are vocal folds open or closed?
open
Air molecules vibrating at a rate in a particular range
Air molecules vibrating at a rate in a particular range
phonatory muscles
-throaryteniod muscles, muscles that move the vocal folds
adductor
lateral cricoarytenoid
abductor
posterior
vocal fold vibration
is result rom buildup of air pressure below vocal fold which is responsible for making exhaled air vibrate.
Rate of vibrations are determinded by
length, mass, tension
pitch
determined by elasticity, tension, mass
hz for females male and children
125 for males
225 for females
up to 400 for children
loudness
degree of subgglottal air pressure
degree of voacal folds compression
factors
- intensity: force with which the folds open and close
-amplitude: extent of vocal fold movement
voice qualifications
affected by Physical symmetry of the folds
Breathy (types of voice qualifications)
Incomplete closure of vocal folds
Harsh (types of voice qualifications)
irregular vibration of vocal folds
Hoarse (types of voice qualifications)
excessive air leakage ad irregular vibration
Nasal (types of voice qualifications)
added to sound when passed through nose
Hyper-nasality (types of voice qualifications)
abnormal nasal resonance
Resonance
Monification of the tone produced at the larynx
Articulators
Moveable parts that play a major role in articulation.
soft palate
velum
Hard palate
Maxillae and cleft of the palate.
jaw
mandible
Parts of the tongue
tip, blade, dorsum, root.
major articulator of tongue
stops airflow and release in plosive manner
constrict air passage and creat friction noises
Stops airflow and releases with a fricative noise
bunniator
muscle of the cheek
Orbicularis Oris
Muscle of the mouth
Neurons
Cntral nervous ststem is made up of billions of theres
Parts of the neuron
nucleus, dendrites, axon
peripheral nervous system
anyting outside the skull and the spinal colum
The cranial nerve
has 12 pairs, referred by Roman numeral, originated from the base of the brain,
where does the cranial nerve connect
connects to peripheral structures of the head neck and face
the cranial nerve info
7 pairs are important to speech hearing and they can be sensory motor or mixed
Trigeminal V
sensory an motor
Consist of three divisions or branches that serve many structure of the face
Facial Vll.
mixed
Senory ascpect is partly tast
mortor aspect is facial movements
