Question 1

superior joint of tmj is blank

Answer 1

gliding

Question 2

inferior joint of tmj is blank

Answer 2

hinge

Question 3

this many bones make up a compound joint

Answer 3

3

Question 4

three “bones” that make up tmj

Answer 4

condyle of mandible, articular disc, articular fossa of temporal bone

Question 5

if we didnt have the gliding joint on top of the hinge joint at the tmj, this would be crushed

Answer 5

parotid

Question 6

hinge joint is aka

Answer 6

ginglymoid

Question 7

gliding joint is blank

Answer 7

arthrodial

Question 8

combination of the two types of joints at the tmj is called blank

Answer 8

ginglymoarthrodial

Question 9

the muscle that attaches to condylar process and disk

Answer 9

lateral pterygoid

Question 10

jaw joint in mammals is formed by blank but in any other jawed animal it is formed by blank

Answer 10

membranous ossification, endochondral ossification

Question 11

tmj forms between these weeks

Answer 11

7-11

Question 12

tmj is totally formed by blank

Answer 12

12th week

Question 13

tmj malformations during pregnancy caused by teratogens can occur during the blank trimester

Answer 13

first

Question 14

lower head of lateral pterygoid attaches here

Answer 14

condylar process

Question 15

upper head of lateral pterygoid attaches here

Answer 15

and forms part of the articular disc

Question 16

mesencymal precursor to temporal bone

Answer 16

glenoid blastema

Question 17

mesenchymal precursor to mandible

Answer 17

condylar blastema

Question 18

meckel’s cartilage plays a blank role in forming tmj

Answer 18

indirect

Question 19

meckel’s cartilage turns into these

Answer 19

sphenomandibular ligament, anterior ligament of malleus, malleus

Question 20

developing condyle of the mandible is called blank because it originates within local mesenchymal condylar blastema

Answer 20

secondary cartilage

Question 21

fully ossified mandible is done at about this age

Answer 21

17

Question 22

pole that is slightly prominent beyond the outer surface of the ramus

Answer 22

lateral

Question 23

pole that juts considerably beyond the surface of the ramus

Answer 23

medial

Question 24

because condyles form an angle between blank anterior to the foramen magnum, radiographs of tmj must be taken at blank projection

Answer 24

145-160, oblique

Question 25

shallow cavity located on the anteromedial aspect of mandibular neck

Answer 25

pterygoid fovea

Question 26

when mandible is in the maximal intercuspaction, the articular surface of the condyle faces the blank slope of the articular eminence and not the blank

Answer 26

posterior, glenoid fossa

Question 27

where the chorda tympani and anterio tympanic artery and vein pass through

Answer 27

petrotympanic fissure

Question 28

posterior slope of eminence is blank than the slope anterior to the crest of the eminence

Answer 28

steeper

Question 29

sometimes the eminence is not developed during the first blank of life so opening mouth has condyle going blank to the crest

Answer 29

10 years, anterior

Question 30

zone of disc without nerves, blood vessels, and takes most pressure

Answer 30

intermediate

Question 31

this is highly innervated and give proprioceptive feedback

Answer 31

articular capsule

Question 32

articular capsule is reinforced laterally only by the blank

Answer 32

temporomandibular ligament

Question 33

medial capsule is reinforced by blank

Answer 33

nothing

Question 34

part of temporomandibular ligament that limits lateral movement

Answer 34

oblique fibers

Question 35

part of temporomandibular ligament that limits posterior movement of condyle and disk

Answer 35

horizontal

Question 36

accessory ligament that attaches on or around the lingula and to the spine of sphenoid bone

Answer 36

sphenomandibular ligament

Question 37

accessory ligament that attaches to the angle of the mandible and to the styloid process

Answer 37

stylomandibular ligament

Question 38

stylomandibular ligament limits excessive blank of the mandible

Answer 38

protrusion
