Term
what is resonation?
Definition
the process by which the voice is modified when some frequency components are dampened and others are enhanced
Term
what three structures modify laryngeal tone?
Definition
pharynx, nasal cavity and oral cavity
Term
the velum is in what position to produce all sounds (except nasals)
Definition
elevated and retracted
Term
what is the source filter theory?
Definition
energy from the vibrating vocal folds (the source) is modified by the resonance characteristics of the vocal tract (the filter)
- the vocal tract is visualized as a series of linked tubes
Term
what governs the resonance characteristics of the vocal tract?
Definition
changes in the configuration and shape of the articulators
Term
what refers to the movement of speech structures to produce speech sounds?
Definition
articulation
Term
what are the three structures of the pharynx?
Definition
laryngopharynx, oropharynx and nasopharynx
Term
what two structures add resonance to sounds produced by the larynx?
Definition
laryngopharynx and oropharynx
Term
most pharyngeal muscles are innervated by which cranial nerves?
Definition
X and XI
Term
what happens when the soft palate is lowered? raised/retracted?
Definition
lowered: coupling of the nasal and oral cavities for nasal sounds or quiet breathing through the nose
raised/retracted: muscles of the pharynx move inward to meet the muscles of the soft palate, and the nasal port is then closed (thus, velopharyngeal closure)
Term
the portion of the maxillary bone that forms the majority of the hard palate is called _______________.
Definition
the palatine process
Term
the outer edges of the maxillary bone are called the _____________
Definition
alveolar process
Term
posteriorly, the maxillary bone joins with which bone?
Definition
the palatine bone - this is where the soft palate attaches
Term
the mandible forms the floor of the ________
Definition
mouth
Term
which part of the mandible houses the teeth?
Definition
alveolar arch
Term
what are the two major functions of the mandible?
Definition
opening and closing the mouth, and chewing the food
Term
what is the major function of the teeth? secondary?
Definition
major: chewing
secondary: production of some speech sounds
Term
what are the four major parts of the tongue?
Definition
tip, blade, dorsum and root
Term
what connects the mandible with the inferior portion of the tongue?
Definition
lingual frenulum
