Occlusal: ____ phase, _____ closing phase, occlusal surface ____ & ____ contaction

1) opening, 10-15 mm, separation of teeth
2) rapid jaw, meet trap food, isotonic contraction
3) power phase, slow jaw or contact phase, in between crush food particles, isometric contraction

Complete the ff:

Incisal
action: _____, teeth: _____

Direct crushing
action: ____ thru mandile, teeth: ____; balance & working side

Mortar & Pestle
action: _____; teeth:____, _____ of food; soundless due to ______

Molar = 91 - 198 lbs (41.3 - 89.8 kg)
Incisor = 29-51 lbs (13.2 - 23.1 kg)

____ major role is take & maneuvering food inside oral cavity and dividing soft food & sweeping food debris after eating

Tongue

_____ is an innate function, series of coordinated muscle contraction that moves the bolus

Deglutition “Swallowing”

Decision to swallow is based on sev factors such as:

1) Degree of fineness of food
2) Degree of bolus
3) Intensity of taste extracted

Stage of swallowing that occurs simultaneously that occurs in what duration?

2) Pharyngeal stage - pharynx
3) Esopharyngeal stage - esophagus

Complete the ff

Oral stage is _____ mechanical process; reflex ____

Pharyngeal stage __________ to avoid choking

Esophageal stage upper section is _____ & lower section is ____

Reflex wave of contraction is also known as _____

2) Air / Nasal passage closes

3) Voluntary; Involuntary

4) Peristaltic waves

Types of swallowing complete the ff Somatic swallow: occurs in ____; tongue ______; give structures _________ Visceral/Infantile swallow: occurs in ___; tongue ____; give structures ______

Somatic: common ppl, tongue: inside the oral cavity, normal seal, occlusion, antero-posterior relationship maxilla & mandible, harmoneous rel w cranial & facial structures Infantile: open bite px, tongue: abnormally large in between maxillary & mandibular gumpads, no normal seal & harmoneous rel, lips are sealed and appear stiff
