module 1 reinforcement

Question 1

which decade is craniofacial skeletal growth completed

Answer 1

upper jaw
-teens to twenties
vertical
- grown throughout our life (50s and later = answer)

Question 2

growth

Answer 2

1) change
2) increase in size and number

Question 3

development

Answer 3

1) increase in complexity
2) gaining cell specialization

Question 4

growth pattern is the predicatable changes in body proportions over time

Answer 4

true

Question 5

maxilla grows faster before mandible during adolescent growth (A)

because it is closer to the brain (B)

Answer 5

a) false, it is BEFORE adolescent growth that it is faster
b) this is true and related

Question 6

cephalocaudal gradient

Answer 6

1) changes in body proportion over time
2) fetus head is 50%
3) at birth 25%
4 )adult 10-14%
—
1) maxilla grows faster than mandible before adolescence

Question 7

maxilla

Answer 7

1) influenced more by growth at the cranial base of the brain
2) accelerates early on then plateaus

Question 8

mandible

Answer 8

1) influenced more closely to the general body curve
2) accelerate, plateau, then growth at the pubertal spurt

Question 9

monitoring

Answer 9

1) male and female
- pediatric growth charts
2) weight and standing height
3) predicts how a patient will grow
- and treat if they do not grow in a normal way
4) pubertal growth spurt is BEST time for mandible ortho treatment

Question 10

craniometry

Answer 10

1) human growth measurements

Question 11

anthropometry

Answer 11

1) living individual measurements

Question 12

cephalometric radiology

Answer 12

1) used in ortho to check CVM

Question 13

6 stages of cervical vertebral maturation

Answer 13

1) working out the timing of ortho treatment
- where are they in skeletal maturation phases
2) C2, C3, C4
- those have specific shapes in growth
- width, height, concavity
3) stage 3 is the best time

Question 14

synchondroses

Answer 14

1) filled with cartilage
2) active, independent growth
3) capable of independent growth

4) not direct ossification
- deposition of bone on bone (aka intramembranous)

Question 15

how does a long bone grow

Answer 15

1) growth plate present
2) grows in a layer of periosteum adjacent to bone surface

Question 16

osteoclasts

Answer 16

1) just does bone resorption

Question 17

endochondral ossification

Answer 17

1) invasion of blood vessels
2) etc

Question 18

intramembranous

Answer 18

1) bony deposition

Question 19

endochondral ossification

Answer 19

1) modelled in cartilage and replaced by bone

Question 20

mandible grows by

Answer 20

1) apposition and remodeling resorption at the ramus
- ramus goes back and pushes lower jaw forward
2) endochondral replacement at condyles
- some growth because of this
3) pulled away from the skull by the growth of the soft tissue

Question 21

mandibular condyle

Answer 21

1) growth cartilage involved in growth
2) site of growth

Question 22

growth centers

Answer 22

1) base of skull (sychondroses)
2) and nasal septum
- pulls maxilla down and forwards

Question 23

which of the synchondroses fuses at birth

Answer 23

1) endochondral ossification that doesn’t fuse immediately
2) at birth
- intra-sphenoidal
3) spheno-occifpital 17-25
3) sphenoethmoidal 6 yr

Question 24

base of brain

Answer 24

1) ethmoid, sphenoid, occipital
- endochondral ossification

Question 25

melvin moss

Answer 25

1) the functional matrix hypothesis

Question 26

secretion of ECM is the most important activity for growth of the craniofacial skeleton

Answer 26

1) true
- gives size and growth

Question 27

bone is

Answer 27

1) grows under tension
2) is tension adapted
3) grows in length at the epiphyseal plate
4) increases in diameter by appositional growth
