Flashcards in Ch 5 Lec 3 - Skeletal System Deck (46):
1

blank cartilage forms model of future bone

hyaline

2

in endochondral ossification, cells differentiate into blank

osteoblasts

3

in endochondral ossification, compact bone forms around the blank

diaphysis

4

spongy bone forms in the center of the model at the blank

primary ossification center

5

in endochondral ossification, the shaft is blank

remodeled

6

two types of cartilage that remain from endochondral ossification

articular, epiphyseal plate

7

the growth plate

epiphyseal plate

8

contact points of bone at joints has this cartilage

articular cartilage

9

bone growth, or elongation occurs at the blank

epiphyseal plate

10

growth in length continues until blank ossification center meet

2

11

the relative thickness of epiphyseal plate does not change until growth is almost blank

complete

12

cartilage depleted and epiphyseal plate narrows into the blank

epiphyseal

13

compact bone is deposited beneath periosteum and bone thickens in this growth

appositional growth

14

bone remodeling occurs blank life in appositional growth

throughout

15

bone remodeling is done by blank and blank

osteoclasts, osteoblasts

16

three types of bone

long, flat, sesamoid

17

longer length than width bones

long bones

18

bones that are thin and compact

flat bones

19

small bones in tendons that protect from wear and tear

sesamoid bones

20

three more types of bones

irregular, sutural, short

21

bone with complex shapes and difficult to categorize

irregular

22

bones that grow between sutures

sutural bone

23

cube shaped bones that have equal length and width

short bones

24

this is when osteoclasts carve out small tunnels and osteoblasts rebuild osteons

bone remodeling

25

blank percent of compact bone is remodeled each year

4

26

blank percent of spongy bone is remodeled per year

20

27

blank is fully remodeled every four months

distal femur

28

blank break does not penetrate skin

simple

29

blank break penetrates skin

compound

30

how the ankle fractures

pott's fracture

31

transverse fracture breaks on a blank

slant

32

fracture that splinters

greenstick fracture

33

fractures where the bone gets pushed out of place

epiphyseal fracture

34

fracture of spine where vertebra crush each other

compression fracture

35

fractures are treated by blank and blank

reduction, immobilization

36

a blank forms within hours of the injury and it is a mass of blood

fracture hematoma

37

blank and eliminate dead cells and matrix

osteoclasts

38

this consists of a mass bridging the broken ends of the bone after about 3 weeks

fibrocartilaginous callus

39

a blank forms after about 3 to 4 months after breaking bone

bony callus

40

a well healed fracture is blank

undetectable

41

bone remodeling can take blank to blank depending on the severity of the fracture

weeks, months

42

three factors affecting growth repair and development of bone

vitamin d, sunlight, balance hormones, physical stress

43

abnormal reduction of bone mass

osteoporosis

44

osteoporosis causes blank in bones

holes

45

fibrodysplasia is when the fibrous tissue becomes blank

ossified

46

fibrodysplasia is a blank disorder and injury results in inappropriate blank formation

genetic, bone
