Speech Anatomy Flashcards
(19 cards)
What are the systems of speech
Respiratory, Phonatory, Resonatory, Articulatory, Nervous system, and auditory system
Define Respiratory
(lungs) provides the energy source for speech
Define Phonatory
(larynx) provides the voicing (all vowels and certain phoneme)
Define resonatory
acoustic source provided by voicing is modified within the pharyngeal, oral and nasal cavities
define articulatory
acoustic source provided by voicing are modified by oral motor structures (mobile and immobile)
define nervous system
(cns and pns) controls musculature, receives and makes sense of input information
define auditory system
processes speech and non speech acoustic signals received and perceived by listener
what are the text system of speech
respiratory, laryngeal, and supralaryngeal
what are the mobile articulators
tongue, lips, velum, soft palate and jaw
what are the immobile artiuclators
alveolar ridge, teeth and hard palate
what are the anatomical structures of the larynx
Epiglottis, Hyoid bone, thryrohyoid membrane, throid cartilage, laryngeal prominences, criticoid cartilage, tracheal cartilage, cricothyroid ligament, trachea
What are the 3 major sections of the pharynx
Laryngopharynx
oropharynx
nasopharynx
what are the supralaryngeal system and articulators?
alveolar ridge, lips, teeth, madible, oral cavity, tongue, velum, hard palate and nasal cavity
What does the parynx do?
It directs airflow from larynx to oral and nasal cavities
Name the basic anatomy of the Larnynx
thyroid cartilage, arytenoid cartilages (2), corniculate cartilages, cricoid cartilages, epiglottis (directs food into the esophagus), hyoid bone, and glottis (space between the vf’s)
what is the difference between adduction and abuduction?
Adduction the vocal folds come together - they close
Abduction the vocal folds seperate - they open
What is the Bernoulli effect?
It is the drop in air pressure created by increased airlfow through a constriction that causes intense vocal fold adduction.
What are the function of inhalation?
- Thoracic cavity expands to allow lungs room to expand
- diaphragm contracts and lowers which expands thoracic cavity
- external intercostal muscles working during inhalation
- pressure differences are what trigger the process of inhalation-exhalation
Describe the functions of exhalation
- Lungs deflate - thoracic cavity space decreases
- Diaphragm relaxes and rises
- Internal intercostal muscles at work during exhalation
- air moves from the lungs into the trachea and up to the level of the larynx which causes the vocal folds to vibrate.
