Exam 3 Flashcards
study guide minus diagrams
creation of speech sounds using movements of vocal tract
Articulation
open vocal tract, always have vocal fold vibration
Vowels
more constricted vocal tract, with or without phonation
Consonants
states that a voices source is generated by vocal folds & routed through vocal tract - this sound then shaped into sounds of speech
Source - Filter Theory
voice sound created by VF (vocal fold) vibration or movement of vocal tract
Source
shape of vocal tract cavities that filter sound
Filter
frequency regions of high acoustic energy caused by vocal tract shape
Resonance
LOOK AT WHERE PHARYNX PARTS ARE LOCATED
LOOK AT WHERE PHARYNX PARTS ARE LOCATED
extends from vocal folds
Laryngopharynx
hyoid up to faucial pillars
Oropharynx
from soft palate to beginning of nasal cavity
Nasopharynx
opening between naso & oropharynx (stays open for nasal sound, closed for everything else - blocks off nasal cavity)
Velopharyngeal Port
very top, from nostrils to nasopharynx
Nasal Cavity
everything in mouth from faucial pillars
Oral Cavity
jawbone, movable articulator, 2 halves fused together
Mandible
where teeth hook, makes up hard palate
Maxillae
bridge of nose, vomer inside
Nasal Bone
teeth, fixed articulators
Dentition
inferior, middle, superior, protrudes into nasal cavity
Nasal Conchae
cheek bones
Zygomatic
around your lips, main muscle of lips, main purpose constrict opening
Orbicularis Oris
muscle of cheek, attaches to orbicularis oris
Buccinator
muscle of jaw, fan like muscle, helps elevate mandible
Masseter
levator superioris - elevates upper lip
Labaii 1
levator superioris alaeque nasi - elevates upper lip
Labaii 2
depressor inferioris - pulls lips down and out
Labaii 3
levator - draws corner of mouth up & medially
Anguli Oris 1
depressor - depresses corner of mouth
Anguli Oris 2
faces out into oropharynx, 1/3 of tongue surface
Tongue Base
2/3 of tongue surface with tongue tip
Tongue Body
2/3 tongue surface with tongue body, speech
Tongue Tip
longitudinal muscles, transverse, vertical
Intrinsic Muscles of Tongue
run the length of tongue, superior ones elevate tongue tip, inferior ones contract to depress tongue tip
Longitudinal Muscles
run with vertical, run from middle out, horizontally, narrow tongue
Transverse Muscles
run with transverse, run up and down, helps depress tongue
Vertical Muscles
genioglossus, hyoglossus, palatoglossus, mylohyiod, styloglossus
Extrinsic Muscles of Tongue
move tongue down, hyo pulls sides of tongue down
Genioglossus & Hyoglossus
helps elevate postierior tongue and lower velum*****
Palatoglussus
fan like, helps depress mandible
Mylohyoid
moves tongue back and up
Syloglossus
levator veli palatini, tensor veli palatini, palatopharyngeus, palatoglussus
Velum Parts
elevates the velum, closes off velopharyngeal port
Levator Veli Palatini
dialates (makes wider), eustachian tube in ear
Tensor Veli Palatini
velum depressor, narrows pharynx
Palatopharyngeus
lowers velum **also helps elevate tongue
Palatoglossus
pulls phayngeal wall forward, constricts opening especially used during swallowing
Superior Pharyngeal Constrictor
constricts middle portion of pharynx
Middle Pharyngeal Constrictor
at level of vocal folds, helps form cricolaryngeous muscles
Inferior Pharyngeal Constrictor
upper esophogeal sphincter, gateway for food into esophagus
Cricolaryngeous
