5 microscopic anatomy of bone

A

OSTEON
LAMELLAE
LACUNAE
CANALICULI
CENTRAL CANAL

27
Q

aka haversian system; composed of central canal, lamellae, lacunae, canaliculi, and osteocytes

A

OSTEON

28
Q

concentric ring of bone tissue

A

LAMELLAE

29
Q

cavity embedded in the lamellae; houses osteocytes

A

LACUNAE

30
Q

tiny canals that directly connect the lacunae/osteocytes to central canal

A

CANALICULI

31
Q

houses blood vessels and nerves

A

CENTRAL CANAL

32
Q

process of bone formation

A

OSSIFICATION

33
Q

two major steps of ossification

A

ENDOCHONDRAL OSSIFICATION
INTRAMEMBRANOUS OSSIFICATION

34
Q

contributes to longitudinal growth

A

ENDOCHONDRAL OSSIFICATION

35
Q

occuring primarily in the bones of skull

A

INTRAMEMBRANOUS OSSIFICATION

36
Q

2 factors affecting bone remodeling

A

CALCIUM LEVELS IN THE BLOOD

PULL OF GRAVITY AND MUSCLES ON THE SKELETON

37
Q

disease in children in which the bone fail of calcify

A

RICKETS

38
Q

is any condition in which bone breakdown outpaces bone formation, causing bones to become weak and porous

A

OSTEOPOROSIS

39
Q

is characterized by excessive and abnormal remodeling

A

PAGET’S DISEASE

40
Q

as for old age, bones become thin and weaken

A

FRACTURES

41
Q

fractures may be classified by 4

A

POSITION OF THE BONE ENDS AFTER FRACTURE

COMPLETENESS OF THE BREAK

ORIENTATION OF THE BREAL RELATIVE TO THE LONG AXIS OF THE BONE

WHETHER THE BONE PENETRATE THE SKIN

42
Q

bone fragments into three or more pieces

A

COMMINUTED

43
Q

bone is crushed

A

COMPRESSION

44
Q

ragged break occurs when excessive twisting forces are applied to a bone; common sports fracture

A

SPIRAL

45
Q

epiphysis separates from the diaphysis along the epiphyseal plate

A

EPIPHYSEAL

46
Q

broken bone portion is pressed inward; typical of skull fracture

A

DEPRESSED

47
Q

bone breaks incompletely, much in the way a green twig breaks

A

GREENSTICK

48
Q

when the blood calcium ion level is too high

A

HYPERCALCEMIA

49
Q

softening of the bones

A

OSTEOMALACIA

50
Q

4 stages in the healing of a bone fracture

A

HEMATOMA FORMATION

FIBROCARTILAGE CALLUS FORMATION

BONY CALLUS FORMATION

BONE REMODELING
