P2-ORTHO PPT 4

-Increase in size and number

-Purely anatomic

-Size, weight and structure

Define growth

-Physiologic & behavioral

-COmplexity

DEfine development

P

-Pattern

-Variability

-TIming

List the 3 concepts of growth

Pattern

This concept is abotu changes that occur from infancy to childhood

VAriability

THis concept of growth is where indifivual differences in the rate & timing of growth among individuals

Timing

THis concept is bioolgical clocks

Infancy

This is rapid growth, length singificantly increases

Childhood

THis is gradually gain height & weight, growth continues at a slower rate

Puberty

This is rapid growth & development, significant hormonal changes

S-curved growth pattern

What pattern is used for general tissues

Adulthood

This is when stop growing taller, muscle mass increases, boen density contineus to strengthen

Genital

In the scammon's curve, this is where rapid acceleration of growth during puberty

CEPHALOCAUDAL GRADIENT OF GROWTH

This is a pattern of growth & development in which the head & upper body develop before the lower body

Deviate from what is deemed normal

Define variability

Neural

In scammon's curve, this is where is it nearly complete by 6-7 years old

-Craniometry

-cephalometrics

-Anthropometry

-3D imaging

lISt the methods of studying physical growth

Lymphoid

In scammon's curve, this is where the tissues at 200% size (10-12 years old)

CRANIOMETRY

THis study is based on mesurements of skulls found among human skeletal remains

Cephalometrics

THis study is on lateral radiograph of the head

Anthropometry

This study is about skeletal dimension on living indiviudals

3D-IMAGING

This study is on CT SCAN MRI

-Intramembranous

-Endochondral

List the 2 bone formation

Intramembranous

THis bone formation is direct bone formation

Endochondral

THis boen formation is indirect bone formation

occurs during growth & development

occurance of modeling

Adulthood

Occurance of remodeling

-OCCURS DURING GROWTH & DEVELOPMENT

-SHAPES THE BONE

-INFLUENCED BY HORMONES

DEFINE MODELING

-OCCURS THROUGHOUT CHILDHOOD

-MAINTINS BONE STRENGTH, REPAIRS DAMAGE

-ADAPTS BONE TO MECHNICAL STRESS

DEFINE REMODELING

-frontal

-Parital

-Occipital

-Temporal

List the bones in cranial vautl

-Occipital (basilar part)

-SPhenoid

-Ethmoid

-Temporal

List the bones of cranial base (endochondral)

Clavicles

1st bone form is?

Intertstitial growth

Type of growht within the tissue

Interstitial growth

THis growth is a characteristic of all soft tissue & uncalcified

iNterstitial growth

THis growht is for lengthening

MSX-1

Predominant cell for tooth formation

-hyperplasia

-HYpertrophy

WHat 2 process is present in interstitial growth

-Appositional growth

This growth cuases widening of the tissues

Appositional growth

THis growth is for tissue growth and bone formation

Endochondral

WHich bone growth is where cartilage turns into bone

-Very accurate values

give advantage to craniometry

Measure at a certain time

disadvantage of craniometry

Slightly variation of measurement

Disadvatnage of anthropometry
