Q

ORIGIN OF THE MASSETER

A

zygomatic arch

17
Q

INSERTION OF THE MASSETER

A

lateral border and corner of mandible

18
Q

ACTION OF THE MASSETER

19
Q

HOW TO TEST THE MASSETER

A

1 finger intraoral and 2 extraoral, ask them to clench, its sore in those who have clenching habit

20
Q

ORIGIN OF THE TEMPORALIS

A

floor of infratemporal fossa

21
Q

INSERTION OF THE TEMPORALIS

A

ant border and coronoid process of mandbile

22
Q

ACTION OF TEMPORALIS

A

elevates and retracts

23
Q

HOW TO TEST THE TEMPORALIS

A

palpate the origin and ask them to clench, feel from the middle of the superior and inferior temporal fossa, forward to the supra-orbital area
tender in those with bruxism

24
Q

WHAT IS BRUXISM

A

clenching and grinding habit

25
ORIGIN OF THE LATERAL PTERYGOID
lateral surface of the lateral pterygoid plate
26
INSERTION OF THE LATERAL PTERYGOID
superior head - intra-articular disc | inferior head - anterior border of condyle
27
INSERTION OF THE LATERAL PTERYGOID
superior head - intra-articular disc | inferior head - anterior border of condyle
28
ACTION OF THE LATERAL PTERYGOID
protrudes and laterally deviates (superior head) depresses (inferior head)
29
HOW TO TEST THE LATERAL PTERYGOID
cant palpate so test response to resisted movement by holding jaw and then getting them to move it tender = if this hurts
30
ORIGIN OF THE MEDIAL PTERGOID
deep head = medial surface of the lateral pterygoid plate | superficial head = tuberosity of the maxilla
31
INSERTION OF THE MEDIAL PTERYGOID
medial surface and angle of mandible
32
ACTION OF THE MEDIAL PTERYGOID
elevates and protrudes
33
HOW TO TEST THE MEDIAL PTERGOID
cant | too deep and doesn't respond to resisted movement
34
WHICH IS THE ONLY MUSCLE WHICH RETRACTS THE MANDIBLE
temporalis
35
WHICH MUSCLES PROTRUDE THE MANDIBLE
medial and lateral pterygoid
36
WHICH MUSLCES ELEVATE THE MANDIBLE
masseter temporalis medial pterygoid
37
WHICH MUSCLES DEPRESS THE MANDIBLE
lateral pterygoid omohyoid thyrohyoid sternohyoid
