17
Q

are primary growth cartilages incorporated into the bone or are they separate

A

SEPARATE

18
Q

what are transient and develop AFTER a bone has started intramem oss

A

SECONDARY growth cartilages

19
Q

what type of cartilage is seondary growth cart

A

FIBROcartilage

20
Q

does the fibrocart in 2º growth cart become incorporated into the bone or stay separate

A

it becomes incorporated or will degenerated after growth is achieved. it is surrounded by developing bone

21
Q

where does 2º growth cart develop

A

in areas of compression and pressure gradients

22
Q

wha are regions of CT b/w bony articulation

A

sutures

23
Q

sutures are the 1º growth sites for

A

mem VC and NC
cart NC

24
Q

what are the synCHONDroses sutures

A

HYALINE cart and endochond oss.

25
Q

where can we find synCHONDroses

A

cart NC –> cranial BASE

26
Q

what are the synDESmoses sutures

A

FIBROUS CT and intramem oss

27
Q

where can we find synDESmoses sutures

A

memb NC and VC and between these two

28
Q

T/F

sutural growth occurs parallal to the suture

A

FALSE. PERPENDICULAR!!

29
Q

T/F

sutural growth ONLY happens as long as the suture is PATENT

A

true!

30
Q

what type of joint is synARTHROSES

A

immoveable!

think ARTHRitis

31
Q

what type of joint is synOSTOSES

A

remnant of an OSSIFIED suture

32
Q

what type of displacement is a growth of a bone moves THE BONE to a new position

A

1º displacement growth

33
Q

what type of displacement is a growth of a NEIGHBORING bone moving an ADJACENT bone to a new position

A

2º displacement growth

34
Q

1º or 2º displacement growth:

the growth of the maxillary tuberosity against the cranial base displaces the maxilla forward

A

1º

35
Q

1º or 2º displacement growth:

the nasomaxillary complex moves down and forward due to the growth of the middle cranial fossa and cranial base

A

2º

36
Q

2º growths of the mandible include

A

condylar
symphyseal
angular

37
Q

what ways does condylar cart grow

A

up, back and out

38
Q

symphyseal cart growth allows for

A

INCREASE in condylar distance

39
Q

angular cart growth allows for

A

INCREASED length in ramus

40
Q

T/F this is an example of displacement growth

growth of cranial base and condylar cart move mandible down and forward

A

TRUE

and i think its 2º??
