Bone Quiz

Question 1

what is the bone’s main composition at the Epiphyses?

Answer 1

spongy bone (enclosed by compact bone covered by articular cartilage)

Question 2

What is the difference between the periosteum and articular cartilage?

Answer 2

different places the protection is in and the different materials each is made out of

Question 3

How does the bone change from puberty to adulthood

Answer 3

the Epiphyseal plate is replaced with Epiphyseal line bone

Question 4

what type of fracture causes a dent?

Answer 4

depressed

Question 5

what are some examples that cause fractures (4)?

Answer 5

• car accidents
• sport injuries
• sudden fall
• disease

Question 6

what is the difference between an open fracture and closed fracture?

Answer 6

• open fracture pierces through the skin

- closed fracture is inside the skin

Question 7

what is bone remodeling?

Answer 7

a life-long process where mature bone tissue is removed from the skeleton, and new bone tissue is formed

Question 8

what is the first step in bone remodeling

Answer 8

resorption (osteoclasts digest old bone)

Question 9

what are osteoclasts

Answer 9

giant bone-destroying cells in bones to break down the bone matrix and release calcium ions into the blood

Question 10

all terms beginning with “T” are?

Answer 10

projections

Question 11

bone markings reveal where:

Answer 11

muscles, tendons, and ligaments were attached

Question 12

which is not a projection?

Answer 12

Fossa

Question 13

what are the types of reductions?

Answer 13

closed reduction and open reduction

Question 14

what is a hematoma

Answer 14

a blood filled swelling in the tissues (bruise)

Question 15

what happens after the hematoma forms? (second step)

Answer 15

the break is splinted by a fibrocartilage callus (a mass of repair tissue) that closes the gap

Question 16

what produces hyaline cartilage

Answer 16

chondrocytes from the epiphyseal plate

Question 17

when do your bones stop growing

Answer 17

girls=after puberty

boys=20s-30s

Question 18

what are osteocytes

Answer 18

mature bone cells

Question 19

explain how osteocytes, lacunae, lamellae, and central canals are related

Answer 19

osteocytes are mature bone cells that are found in tiny cavaties within the matrix which is the lacunae. The lacunae make up the concentric circles of the lamellae the canals that surround in the central canals

Question 20

how is microscopic anatomy broken down and what does each part entail

Answer 20

cytology=analysis of structure of individual cells

histology=examination of tissues

Question 21

what are perforating canals?

Answer 21

canals that run into the compact bone at right angles to the shaft that completes the communication pathay from the outside of the bone to its interior

Question 22

define a greenstick fracture

Answer 22

bone does not break all the way around the outside layer

Question 23

what hormone is released into blood during bone remodeling

Answer 23

parathyroid hormone

Question 24

what is the head

Answer 24

a bony expansion carried on a narrow neck

Question 25

two factors that affect height

Answer 25

genetics and nutrition
