Q

65% of bone volume is

A

calcium and phosphate mineral salts

26
Q

osteoblasts build

A

bone

27
Q

mineral salts bind around collagen fibers which

A

makes bones hard

28
Q

osteoblasts secrete

A

osteoid

29
Q

osteoids included

A

ground substance and collagen

30
Q

osteoids help with bone

A

flexibility and tensile strength

31
Q

four types of bone cells types

A

osteoprogenitor cells, osteoblasts, osteocytes, osteoclasts

32
Q

osteoprogenitor cells are

A

stem cells, give rise to osteoblasts and cytes,

33
Q

osteoprogenitor cells line

A

lining outer surface of bone, crucial in bone fracture

34
Q

osteoblasts arise from

A

ostgeoprogenitor cells

35
Q

osteogenesis is made by

A

osteoblasts

36
Q

osteoblasts trapped in tissue is

A

osteocytes

37
Q

osteocytes maintains

A

health and structure

38
Q

osteoclasts come from

A

hemotopic blood cells

39
Q

osteoclasts job is to

A

break down bone

40
Q

two types of bone

A

spongy and compact

41
Q

spongy bone is

A

deeper in

42
Q

denser bone on outside of bone

A

compact bone

43
Q

osteon is

A

center has space called central canal

44
Q

from the central canal there is rings of tree called

A

lamella

45
Q

perferating canals connects

A

central canal of one osteon to another

46
Q

between bone lamella there are

A

spaces called lacuna

47
Q

osteocytes reside in

A

lacuna

48
Q

lacuna are connected through

A

canaliculus

49
Q

prior to 8 weeks of gestation is

A

no bones

50
Q

bone tissue begings to develolp through

A

intramembranous ossification

51
Q

intramembranous ossification begins with

A

fibrous membrane turning to a bone

52
Q

spicules form within

A

fibrous membrane

53
Q

endochondral means it is in the

A

cartilage

54
Q

thin layer of cartilage present on both ends of bone called

A

epiphysial plate

55
Q

when your epiphyseal plate goes to line this means

A

done growing

56
Q

bones change how mujch

A

all the time

57
Q

once a decade all of what type of bone is replaced

A

compact

58
Q

bone remodeling

A

is osteoblasts lay down near bone and osteoclasts resorbing old bone

59
Q

spongy bone is replaced every

A

3-4 years

60
Q

bone remodeling prevents

A

brittle bone
