Articulation, Resonation, and Ingestion Lecture Notes

Vocabulary flashcards covering the anatomy, terminology, and pathology associated with articulation, resonation, and deglutition.

Articulation (Speech Definition)

Process of bringing the mobile and immobile articulators into contact for the purpose of shaping the sounds of speech.

Articulation (Anatomy Definition)

Connect or join together.

Resonation

The sound quality given to voiced sounds by the vocal tract.

Deglutition

Swallowing.

Mastication

Chewing.

Bolus

Ball of food or liquid to be swallowed.

Vocal Tract

The system consisting of the nasal cavity, oral cavity, and pharynx.

Mobile Articulators

Lips, tongue, mandible, velum (soft palate), pharynx, fauces (faucial pillars), cheeks, and uvula.

Immobile Articulators

Hard palate, alveolar ridge, and teeth.

Bones of the Face

Mandible, maxillae, nasal bones, inferior nasal conchae, vomer, zygomatic bones, lacrimal bones, palatine bones, and hyoid.

Bones of the Cranial Skeleton

Frontal, parietal, sphenoid, ethmoid, temporal, and occipital.

Craniosynostosis

When the sutures of the skull become ossified prematurely; can affect brain development and may require surgery.

Dental Development (Permanent Teeth)

The stage of dentition containing $16$ teeth in each arch.

Dental Development (Deciduous Teeth)

Also known as baby teeth, consisting of $10$ teeth in each arch.

Class I Dental Occlusion (Neutrocclusion)

Normal position where the first mandibular molar is $\frac{1}{2}$ tooth anterior to the first maxillary molar.

Class II Malocclusion

Condition where the first mandibular molar is posterior to normal position and the mandible is retracted.

Class III Malocclusion

Condition where the first mandibular molar is anterior to normal position and the mandible is protruded.

Micrognathia

Condition in which the mandible is small in relation to the maxilla, which may interfere with infant feeding.

Open Bite

Condition where anterior teeth do not occlude because of excessive eruption of posterior teeth.

Closed Bite

Condition where posterior teeth do not occlude because of excessive eruption of anterior teeth.

Buccal Cavity

The space between the teeth and the cheeks.

Ankyloglossia

Known as tongue tied; characterized by a short, thick, or tight lingual frenulum that restricts the tongue's range of motion.

Source-Filter Theory of Vowel Production

States that speech is the product of sending an acoustic source, such as vibrating vocal cords, through the filter of the vocal tract that shapes the output.

Dysphagia

Any difficulty, discomfort, or pain associated with swallowing; a swallowing disorder.
