yellow marrow

Question 12

site of longitudinal growth in a child

Answer 12

epiphyseal plates

Question 13

Why do bone injuries heal faster than cartilage injuries?

Answer 13

bones have a higher blood supply which contains more nutrients to heal

Question 14

Bone cells

Answer 14

osteocytes

Question 15

where are osteocytes located?

Answer 15

lacunae

Question 16

Immature or matrix-depositing bone cells

Answer 16

osteoblast

Question 17

Bone cells that liquefy bone matrix and release calcium to the blood

Answer 17

osteoclast

Question 18

Why do astronauts do isometric exercises when in space?

Answer 18

lack of gravity

Question 19

Residences of osteocytes

Answer 19

Lacunae

Question 20

Longitudinal canal carrying blood vessels and nerves

Answer 20

haversian canal

Question 21

Nonliving structural part of bone

Answer 21

bone matrix

Question 22

Tiny canals connecting lacunae

Answer 22

canaliculi

Question 23

What is the function of the inorganic part of the matrix?

Answer 23

flexibility and strength

Question 24

The formation of bone

Answer 24

ossification

Question 25

how does intramembraneous bones form?

Answer 25

Osteoblasts appear in the connective tissue and deposit bony matrix which makes spongy bone form

Question 26

How does endochondral bones form?

Answer 26

Cartilage models form and rapidly divides, forms compact bone and blood vessels

Question 27

Name two ways the fetal skull differs from the adult skull

Answer 27

Fetal skull can still move around because it still has soft spots. Adult skulls have the parts of the skull fused together making the head more durable

Question 28

A break in a bone

Answer 28

fracture

Question 29

What are the 6 types of fractures?

Answer 29

spiral, greenstick, fissured, comminuted, transverse, oblique

Question 30

How do fractures heal?

Answer 30

Blood escaping from the damaged blood vessels form a hematoma, spongy bone and fibrocartilage form, bony callus replaces the cartilage and osteoclasts remove the excess bony tissue

Question 31

What are 2 factors that keep bones healthy?

Answer 31

good nutrition and exercise

Question 32

What are 2 factors that can cause bone to become soft?

Answer 32

lack of nutrition (minerals) not enough calcium in bones

Question 33

Putting bones back in place

Answer 33

Reduction

Question 34

A cylinder shaped unit including bone cells that surround a central canal

Answer 34

Osteon

Question 35

Fracture that occurs on the convex surface of the bend in the bone

Answer 35

Greenstick

Question 36

Longitudinal break in bone

Answer 36

Fissured

Question 37

A complete fracture and fragments in the bone

Answer 37

Comminuted

Question 38

Break occurs at a right angle to the axis of the bone

Answer 38

Transverse

Question 39

Occurs at an angle other than at a right angle to the axis of the bone

Answer 39

Oblique

Question 40

Caused by excessive twisting of a bone

Answer 40

Spiral

Question 41

Consists of the bones of the upper and lower limbs and the bones that anchor the limbs to the axial skeleton

Answer 41

Appendicular skeleton

Question 42

Consists of bony and cartilaginous parts that support and protect the organs of the head, neck, and trunk

Answer 42

Axial skeleton

Question 43

How many bones are included in the appendicular skeleton?

Answer 43

126

Question 44

How many bones are included in the axial skeleton?

Answer 44

80
