Q

PMR:

A 
Perio Mechanical Receptors
Regulate force by teeth, adapt load
Slow apex, fast fulcrum
More sensitivity to low force = implication >high occ

A

Pain and Temp

20
Q

Proprioception travels through

A

Mesencephalic nucleus V (Midbrain)

21
Q

Mesencephalic nucleus V (Midbrain) deals with

A

22
Q

Reflexes:

A
  1. Jaw close/Jaw Jerk
  2. Opening
  3. Unloading
  4. Tooth contact
  5. Horizontal
23
Q

Jaw close/Jaw Jerk Reflex:

A

Stretch spindle in masseter (7-12ms)

-Tap chin in rest = contract = teeth occlude

24
Q

Opening Reflex:

A

Polysynaptic > Mech/Elec stimuli to lips/gingiva/mucosa

=Opening > inhibit md elevator w/o stim cont of depressor

25
Q

Unloading Reflex:

A

Protective > sudden unload > inhibits elevators and excites depressors (PDL)
- bite on stone during mastication

26
Q

Tooth contact reflex:

A

transient, silent then increase and decrease elevator, nothing in depressors (snap together)

27
Q

Horizontal reflex:

A

Lateral, protrusive = retrusive md

28
Q

2 point detection

A

tip of tongue

29
Q

Cold and warm felt most:

A

Dorsum of tongue

30
Q

Cold only felt:

A

gingiva > Bu Mu> palate
