Q

What is the origin and insertion of the lateral pterygoid muscle?

A

Origin: sphenoid bone and pterygoid plate

Insertion: capsule and neck of mandible

17
Q

What actions does the lateral ptyergoid muscle do?

A

Anteriorly rotates disk on the condyle during closing, jaw protrusion, opening and deviation to the opposite side

18
Q

What cranial nerve supplies all muscles of mastication?

A

CN V - Trigeminal Nerve

19
Q

The arthorkinematics of the TMJ involve rotation and _____ translation in the sagittal, horizontal, and frontal planes

A

anterior

20
Q

Protusion and retrusion are _____ glides

A

planar

21
Q

Describe the arthrokinematics of the TMJ during mouth opening

A

The condyles begin to rotate anteriorly and translate inferiorly and laterally during first the 25 degrees. Then during the last 15 degrees the collateral ligaments tighten and rotation ceases which allows for translation of the disc and condyle to occur together

22
Q

Decreased mouth-opening due to masseter stiffness (clinching) can lead to what?

A

Over-recruitment of the upper cervical extensors, which leads to associated cervicogenic headaches and compressive TMJ pain

23
Q

What does centric relation test for?

A

Identification of pain caused by malpositioning

24
Q

What is indicated if there is pain associated with the centric relation test?

A

That the cause of malpositioning could possibly be due to structural problems

25
Q

What is indicated if there is no pain associated with the centric relation test?

A

That the cause of malpositioning is functional

26
Q

What is considered normal maximal opening of the mouth?

A

50 mm

27
Q

What is considered funtional opening of the mouth?

A

40 mm

28
Q

How do you elicit the TMJ reflex?

A

The patient’s mouth is relaxed and opened in the resting position. Clinician places their thumb on the mandible and lightly taps thumb with hammer. The mouth should close.

29
Q

Which 2 cranial nerves should be tested on all TMD patients?

A

CN V and VII

30
Q

True or False

HVLA manipulations (grade 5 mobilizations) can be used on the TMJ

A

False

31
Q

What is the goal of PIR?

A

The goal of post-isometric relaxation is relaxation of hypertonic or overactive muscles
