Answer 10

AFTER!

Question 11

T/F:

2º growth cartilages undergo endochondral oss and are hyaline cart

Answer 11

FALSE. they are FIBROCART

Question 12

mand 2º growth cartilages:

Answer 12

coronoid, angular cart, condylar, symphyseal

Question 13

maxilla 2º growth cartilages

Answer 13

zygoma, palatal and articular eminence

Question 14

what develops PRIOR to bone and usually is a precursor that undergoes endo oss. and contributes the specific skull bones

Answer 14

PRIMARY growth cartilages

Question 15

what type of ossification do primary growth cartilages undergo

Answer 15

endochondral oss –> hyaline cart!

Question 16

what type of cart is primary growth cart

Answer 16

HYALINE

Question 17

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

Answer 17

SEPARATE

Question 18

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

Answer 18

SECONDARY growth cartilages

Question 19

what type of cartilage is seondary growth cart

Answer 19

FIBROcartilage

Question 20

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

Answer 20

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

Question 21

where does 2º growth cart develop

Answer 21

in areas of compression and pressure gradients

Question 22

wha are regions of CT b/w bony articulation

Answer 22

sutures

Question 23

sutures are the 1º growth sites for

Answer 23

mem VC and NC
cart NC

Question 24

what are the synCHONDroses sutures

Answer 24

HYALINE cart and endochond oss.

Question 25

where can we find synCHONDroses

Answer 25

cart NC --> cranial BASE

Question 26

what are the synDESmoses sutures

Answer 26

FIBROUS CT and intramem oss

Question 27

where can we find synDESmoses sutures

Answer 27

memb NC and VC and between these two

Question 28

T/F sutural growth occurs parallal to the suture

Answer 28

FALSE. PERPENDICULAR!!

Question 29

T/F sutural growth ONLY happens as long as the suture is PATENT

Answer 29

true!

Question 30

what type of joint is synARTHROSES

Answer 30

immoveable! think ARTHRitis

Question 31

what type of joint is synOSTOSES

Answer 31

remnant of an OSSIFIED suture

Question 32

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

Answer 32

1º displacement growth

Question 33

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

Answer 33

2º displacement growth

Question 34

1º or 2º displacement growth: the growth of the maxillary tuberosity against the cranial base displaces the maxilla forward

Answer 34

1º

Question 35

1º or 2º displacement growth: the nasomaxillary complex moves down and forward due to the growth of the middle cranial fossa and cranial base

Answer 35

2º

Question 36

2º growths of the mandible include

Answer 36

condylar symphyseal angular

Question 37

what ways does condylar cart grow

Answer 37

up, back and out

Question 38

symphyseal cart growth allows for

Answer 38

INCREASE in condylar distance

Question 39

angular cart growth allows for

Answer 39

INCREASED length in ramus

Question 40

T/F this is an example of displacement growth growth of cranial base and condylar cart move mandible down and forward

Answer 40

TRUE and i think its 2º??
