Q

maxilla grows faster before mandible during adolescent growth (A)

because it is closer to the brain (B)

A

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

cephalocaudal gradient

A

1) changes in body proportion over time
2) fetus head is 50%
3) at birth 25%
4 )adult 10-14%

Q

maxilla

A

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

Q

mandible

A

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

Q

monitoring

A

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

Q

6 stages of cervical vertebral maturation

A

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

Q

synchondroses

A

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

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

16
Q

osteoclasts

A

1) just does bone resorption

17
Q

endochondral ossification

A

1) invasion of blood vessels
2) etc

18
Q

intramembranous

A

1) bony deposition

19
Q

endochondral ossification

A

1) modelled in cartilage and replaced by bone

20
Q

mandible grows by

A

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

21
Q

mandibular condyle

A

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

22
Q

growth centers

A

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

23
Q

which of the synchondroses fuses at birth

A

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

24
Q

base of brain

A

1) ethmoid, sphenoid, occipital
- endochondral ossification

25
Q

melvin moss

A

1) the functional matrix hypothesis

26
Q

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

A

1) true
- gives size and growth

27
Q

bone is

A

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