3 basic cavities for sound production:
- Nasal Cavity
- Oral Cavity
- Pharynx
- Vocal folds→ the sound source, oscillating vocal folds; when the oscillate, they create
a vocal tone
- Sound waves move up to either the oral or nasal cavity
- Vowels create through placement and tenseness of the tongue
- Consonantsturbulence
- /s/ vs. /∫/ is lip rounding
- ***cavity size and dimension changes in order to create different sounds***
Articulators:
- Lips
- Velum
- Tonuge
- Mandible/Jaw→ helps open oral cavity
- Alveolar ridge
- Hard palate
- Teeth
Bones of the Skull:
- Mandible→ known as jaw bone, one bone; part of the facial skeleton, connected to the
cranium
- Teeth come out of the mandible in their own little holes; grows out of the alveolus
- Corpus: body of the mandible
- Foramen→ holes for blood vessels and nerve tissue to go through
- Angle: at posterior of the corpus
- Ramus: on both sides above the angle
- Condyle: area where the joint of the mandible and the cranium connect
- Coronoid Process: front point of the condyle; connects with muscles
- Mylohyoid Line: where mylohyoid connects
- Mental Prominence: chin
- Maxilla→ two bones that come together in utero; considered a paired bone
- Frontal Process: connects with the frontal bone
- Zygomatic process: connects with zygomatic bone
- Maxillary sinus: cavity; can fill with secretions causing sinus headaches
- Alveolus (alveolar process): where the teeth come out
- Hard Palate: has many suture lines that fused in utero
- Premaxilla: little triangle, with premaxillary sutures
- Palatine Process: two of them; joined by intermaxillary suture
- Incisive foramen: junction of premaxillary and intermaxillary suture
- Transverse Palatine Suture: separates the maxilla from the palatine bone
- ***child with cleft palate has an issue with the sutures

- Palatine Bone behind the maxilla
- Sphenoidal Process
- Orbital process: connects the orbit of the eye
- Horizontal Plate: posterior third of the hard palate; part of palatine bone
Taste:
- Sweet
- Sour
- Bitter
- Umami (savory/protein based)
- Salty
→ if you add smell to taste, then it becomes flavor
Chemesthesis: chemical reaction to putting things in your mouth
People with highly concentrated tastebuds→ supertasters
People with less concentrated tastebuds→ tasters
Carbonation→ when you feel the fizziness, that is considered pain
Tactile feedback→ the feeling of the “crunch” and texture when eating
- Taste and cravings for certain foods have a basis on what your mother ate during her
pregnancy
Behavior:
- Perception:
- Sweet
- Salty
- Sour
- Bitter
- Ingestion
- Tongue protrusions
- Salivation
- Insulin release
- Swallowing
- Protection
- Gag→ protects you from something that is toxic/not good for the body
- Coughing→ larynx protection that will remove liquid from lungs
- Retch
- Vomit→ very protective, includes the gag to remove the food.
- Salivation
Glossopharyngeal nerve IX→
