Anatomy of Articulation + Resonation Flashcards
vocal tract consists of
oral cavity
nasal cavity
pharynx
source filter theory of speech production
vocal folds produce a tone that is passed through vocal tract filter which is manipulable so you can change its shape and therefore change the sound
oral, nasal, pharynx linkage
provides the variable resonating cavity that produces speech
source
vocal fold oscillation
produces many frequencies
fundamental frequency
lowest frequency component of sound source which corresponds to rate of vibration of vocal folds
filter
vocal tract
boosts some frequencies and damps others based on vocal tract shape and size
(lets liquid through and traps particles)
mobile articulators
tongue (largest)
mandible (2nd largest)
velum (soft palate)
lips
cheeks
pharynx
larynx and hyoid
immobile articulators
alveolar ridge of maxilla
hard palate
teeth
external nose
hyaline cartilage plates and bones
nares or nostrils
where nasal cavity begins
choanae
posterior opening into pharynx where nasal cavity begins
vestibule
anterior part of nasal cavity
nasal septum
wall of tissue that divides nasal cavity in half
conchae
3 lateral bony ridges
meatus
tunnels beneath each concha where air passes through
bony nasal septum
made up of vomer, perpendicular plate of ethmoid bone and midline septal cartilage
cribiform plate
olfactory system
horizontal plate of palatine bone
behind palatine process of maxilla
how many molars
12
how many premolars
8
how many canines
4
how many incisors
8
crown
visible part of tooth above gum line
root
portion of tooth below gum line
enamel
wear-resistant outer layer of dental crown
dentin
tissue beneath enamel
pulp
soft living tissue in center of tooth
contains nerves and blood vessels
cementum
bony tissue covers root and anchors to jawbone
gingiva
soft tissue surrounding and support tooth
protecting it from bacteria and trauma
