Articulation System 1

Articulation

sound shaper system

Mobile articulators

tongue, mandible, velum, lips, cheeks, fauces, pharynx, larynx

Articulation

sound shaper system

Mobile articulators

tongue, mandible, velum, lips, cheeks, fauces, pharynx, larynx

Immobile Articulators

alveolar ridge, hard palate, teeth

Source-Filter Theory

Sound source at VF or slightly above, then articulators act as a filter to block some things and allow others to pass through

Sound source

Glottal and supraglottal

Filter

Vocal tract

Facial bones

lacrimal, nasal, palatine, zygmatic, inferior nasal concha, vomer, maxilla and mandible

Cranial Bones

Parietal, frontal, occipital, temporal, sphenoid, mandible and maxilla, nasal, ethmoid

Parts of tooth

Crown, root, enamel, dentin

Labial surface

outer part of front teeth on top and bottom touches lip

-front 4-6

Buccal surface

outer surface of teeth touches cheek laterally

-bicuspids and molars

Incisal surface

bottom part of teeth, where they touch against eachother

Palatal surface

touches your palate

Occlusal surface

parts of teeth that are going to touch together

-closure

Distal

Back most molar

Mesial

Space between teeth

Occlusal

Top of molar

Class 1

bad closure

teeth crooked

Class 2

Overbite

Class 3

Underbite

Openbite

teeth don’t touch in the front

Overjet

Over but teeth are bent

buck teeth

Pharyngeal Cavities

Nasopharynx, oropharynx, laryngopharynx

Oral Anterior cavity

Teeth and alveolar processes

Oral Superior cavity

Palate (hard and soft)

Oral Inferior cavity

Tongue and floor of mouth

Oral Posterior cavity

Palatoglossal arch

Mandibular Muscles: Elevators

masseter, temporalis, medial pterygoid, lateral pterygoid

Intrinsic Tongue Muscles

Superior longitudinal, inferior longitudinal, transverse, vertical

Job of Intrinsic Tongue Muscles

Change shape of tongue

Job of Extrinsic Tongue Muscles

Change movement of tongue

Extrinsic Tongue Muscles

Pharyngeal Muscles

constrictors: superior, middle, inferior- cricopharyngeus and thyropharyngeus

salpingopharyngeus

stylopharyngeus

TMJ Disorder (tempomandibular joint)

temporomandibular ligament- temporal bone to mandible

sphenomandibular ligament- sphenoid bone to mandible

stylomandibular ligament- styloid process to mandible
