Articulatory/resonance Structures W8 Flashcards
(11 cards)
vocal tract
supra laryngeal system consists of a series of cavities, muscles, bones, teeth from the larynx to the lips
identify parts of the vocal tract

oral cavity, nasal cavity, pahryngeal cavity
identify the parts of the oral cavity


movable vs fixed parts of oral cavity
movable: tongue, mandible, velum, lips
fixed: teeth, alveolar ridge, hard palate
lips

philtrum
vermillion zone - border
cupids bow
teeth
2 sets of teeth - 20 in childhood deciduous teeth, 32 in adulthood permanent teeth
4 types of teeth, incisors - chisel, cuspids - canine, premolars - flat, molars - flat

teeth alignment
occlusion or malocclusion

tongue
muscular hydrostat
dorsum
body
root
blade
apex
lingual frenulum
lingual septum
longitudinal median sulcus

mandible
articulates with the temporal bone of the skull
TMJ - condular process of mandible and mandibular fossa of temporal bone separated by fibrocartilage
articulation is held in place by ligaments
allows vertical, anteroposterior, and lateral movement
faucial pillars
anterior - palatoglosses
posterior - palatopharyngeus

velopharyngeal port

space between the velum and the posterior pharyngeal wall
regulates communication between oral and nasal cavities
velum approximates ppw, port is closed - levator veli palatini, superior pharyngeal constrictor, musculus uvulae
velum and PPW are separated, port is open - palatopharyngeus, palatoglossus, tensor veli palatini
