Morph Module 2 Quiz 3

Front 1

Behavior Pattern

Back 1

Muscle activity
Reflex
Brain Feedback

Front 2

Factors Guiding conditioned reflex patterns

Back 2

Proprioception in PDL & TMJ
Sensation from oral mucosa & tongue
Muscles of mastication

Front 3

Factors influencing pattern of mastication

Back 3

Incisal guidance
Curve of spee
Plane of occlusion
condylar guidance
Incline planes or cusp angles

Front 4

Chewing cycle

Back 4

.6-1 sec
Time of tooth contact .2 sec

Front 5

Texture of food influence

Back 5

Softer foods are chewed at lower rate
Coarser the food, the greater the lateral component of chewing cycle

Front 6

Conditions that produce asymmetric lateral movements

Back 6

Pain, interference, absence of teeth, TMJ dysfunction

Front 7

stages of swallowing

Back 7

Voluntary
Involuntary
Reflex muscle activity

Front 8

Stage 1

Back 8

Formation of bolus
Lips closed to seal oral cavity
Bolus on hard palate
Max intercuspation to stabilize mandible
Bolus on soft palate triggers reflex

Front 9

Stage 2

Back 9

Bolus reaches pharynx & contrictors move bolus into esophagus
Epiglottis closes
Eustachian tubes open

Front 10

Stage 3

Back 10

Reflex muscle activity
Bolus goes from esophagus to stomach,

Front 11

Tooth contacts during swallowing

Back 11

Liquids cause light to no contact
Solids cause .683 seconds of contact

Front 12

Determinants of stomatognathic system

Back 12

Left & right TMJ
Occlusion
Neuromuscular system

Front 13

Initiating position

Back 13

Centric relation
Most easily reproduced

Front 14

Three planes in direction of motion

Back 14

Frontal plane
Saggital plane
horizontal plane

Front 15

Clinical significance of condylar angle

Back 15

Greater the angle of condylar eminence, the longer the cusps must be

Front 16

Side shift of working condyle

Back 16

Greater the sideshift, the more mesial lingual groove of mandibular first molar will be

Front 17

Vertical & horizontal overlap of anterior teeth

Back 17

Vertical - Greater the overlap, longer the cusps of posterior teeth

Horizontal - Lesser the overlap, the longer cusps must be
