Chapter 6 - Anatomy of Articulation and Resonation Flashcards
vocal tract
-nasal passages, oral cavity, larynx
pharynx
-laryngopharynx, oropharynx, nasopharynx
phoneme production (source-filter theory)
sound source: larynx (voiced), constriction of tract (voiceless)
filter: vocal tract
articulation
joining structures together
articulators
mobile articulators, immobile articulators
mobile articulators (5)
mandible, lips, tongue, velum, vocal folds
immobile articulators (3)
maxillae, hard palate, alveolar ridge
bones of the face (6)
mandible, maxillae, nasal bones, palatine bones, vomer, zygomatic bone
mandible (6 features) - unpaired
ramus, coronoid process, condylar process, mylohyoid process, mental symphysis, alveolar process
microagnathia
small mandible, not enough room for tongue and floor of mouth
maxillae anterior (5 features)
- 2 parts fused in the middle
frontal process, infraorbital margin, zygomatic process, nasal crest, alveolar process
maxillae underneath 5 features
intermaxillary suture (where the maxillae fuse together), premaxilla-fused by the premaxillary suture, incisive foramen, palatine process,
canine fossa - on top of canine teeth,
cleft lip
-premaxillary suture fails to fuse (unilateral or bilateral)
-may or may not include alveolar process
SLP concerns with cleft lip
feeding/swallowing, articulation, resonance (not usually affected)
maxillary deficiency or maxillary hypoplasia
maxilla is underdeveloped
occlusion
upper and lower teeth into alignment
class I occlusion
normal orientation of mandible and maxillae
class II malocclusion
retracted mandible
class III malocclusion
advanced mandible
overbite vs overjet
overbite is vertical (whole lower teeth is covered)
overjet is horizontal (there’s a wide gap only)
parts of the nasal septum
vomer, perpendicular plate of the ethmoid bone, septal cartilage (there’s also the nasal bone)
what bone forms the cheekbone?
zygomatic bone
