no it is avascular and aneural

Question 9

what is the retrodiscal tissue attached ant and post

Answer 9

the post capsule and the ant tympatic plate

the condyle view the medial and lateral ligament

Question 10

what are disc issue normally due to

Answer 10

stretching of retrodiscal tissue

Question 11

what happens when we open the mouth

Answer 11

the disc moves forward with the condyle and creates stress on the retrodiscal tissue

Question 12

what happens when we close the mouth

Answer 12

the retrodiscal tissue pulls the disc back to move with the condyle

where is the upper compartment

Answer 13

disk and mandibualr fossa

Question 14

where is the lower compartment

Answer 14

disc and the condyle of the mandicular bone

Question 15

what plane does the mouth move in for opening and closing

Answer 15

cornal
- plane passes through the condyles

Question 16

phase 1 of opening

Answer 16

rot of the condyle in the lower compartment

Question 17

pahse 2 of opening

Answer 17

translation of the disc and the condyle together in the upper compartment

Question 18

closing and opening phases

Answer 18

close is the same as opening but opp

Question 19

who much movement do we see with opening

Answer 19

40-50 mm

Question 20

what kind of movement are mandibular protrusion and retrusion

Answer 20

translation movement

Question 21

what comp does protrusion and retrusion occur in

Answer 21

upper comp

Question 22

how much movement do we see with protrusion

Answer 22

6-9 mm

manible juts forward

Question 23

how much movement do we see with retrusion

Answer 23

3 mm
mandible pulls back

Question 24

mandibular lateral deviation axises

Answer 24

vertical and horizontal axis AP axis

Question 25

vertical axis for mandibular lateral deviation

Answer 25

spin around the isp condyle translation of contra condyle

Question 26

how much movement do we see with mandibular lateral deviation

Answer 26

8 mm

Question 27

A-P axis mandibular lateral deviation

Answer 27

spin in the frontal plane of isp condyle depression of contra condyle

Question 28

what motions are see in chewing and griinding

Answer 28

all of the motions

Question 29

what do we use to open our mouth

Answer 29

grvaity, inf lateral pyertiod, ant epigastric

Question 30

mouth closers

Answer 30

temporalis, masseter, medial pyterygoid, sup lat pyertiod - keeps disc sligtly forward during closing

Question 31

right laterl deviator muslces

Answer 31

left medial and lat ptyeriod right post temporilis muscle

Question 32

left lat deviators

Answer 32

right medial and lat ptyeriod left post temporilis muscle

Question 33

protruders

Answer 33

bilat infer ptyeroids assisted by medial ptyeroids

Question 34

retruders

Answer 34

post temporalis muscle post diagastric deep masseter

Question 35

DDWOR

Answer 35

history of jaw locking or catching

Question 36

DDWR

Answer 36

opening or closing clicks - disc displacement with reduction

Question 37

lateral pyter what is the cheif complaint if you see this issue

Answer 37

lateral face pain - pain reproduced with resisted protrusion

Question 38

power stroke

Answer 38

forced closing of the mouth

Question 39

macrotrama TMD

Answer 39

fracture dislocation

Question 40

diseas and TMD

Answer 40

OA RA infections

Question 41

reffered pain TMD

Answer 41

referred pain around the eyes, ears, zygomatic arch, temple areas

Question 42

ear problem with TMD

Answer 42

tinnitus - ringing of the ears

Question 43

where do we palpate

Answer 43

lateral pole behind lateral poles along the lateral ligamament

Question 44

unilateral loading with gauze

Answer 44

gauze - distraction non gauze - closing down

Question 45

what does no pain mean with compression

Answer 45

release means reliefs of compression

Question 46

what does pain with comrpession mean

Answer 46

the capsule is irritated from tensile loads

Question 47

anterior disc location that reduces - openeing

Answer 47

loud clicking during opening - this means the disc has relocated

Question 48

anterior disc location that reduces - closing

Answer 48

the disc has been displaced ant, condyles behind the disc

Question 49

anterior disc location that does not reduce general

Answer 49

no clicking - there are restriction during opening may have a past history of clicking but this is gone now

Question 50

anterior disc location that does not reduce - what is the issue

Answer 50

restriction due to disc blocking translation

Question 51

TMJ capsular restrictions

Answer 51

deviation to the right with less opening deviation to the right with protrusion decrease L lat movements there is not history of clicking there is not snapping on the distraction of the joint

Question 52

TMJ subluxation

Answer 52

excessive opening palpate lateral pole to see with they move to far forward may hear a nosie at the start of close or end of large open may be due to muscle imbalances

Question 53

what do we see with unilateral sublux

Answer 53

might see quick deviation to the contralateral side at the end of openeing

Question 54

translation occurs to soon with opening

Answer 54

jutting of the jaw forward with opening may be due to muscle imbalances

Question 55

what to do with translation occuring to soon

Answer 55

focus on neuromuscluar reducation

Question 56

what does head posture have to do with TMD

Answer 56

forawrd head can effect the position of the manibles may result in a bad bite pattern
