Q

small bones in tendons that protect from wear and tear

A

20
Q

three more types of bones

A

irregular, sutural, short

21
Q

bone with complex shapes and difficult to categorize

22
Q

bones that grow between sutures

A

sutural bone

23
Q

cube shaped bones that have equal length and width

A

short bones

24
Q

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

A

bone remodeling

25
blank percent of compact bone is remodeled each year

26
blank percent of spongy bone is remodeled per year

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
