Q
Medullary cavity
A
The hallow centre region in a long bone containing bone marrow
25
What does the medullary cavity contain
Yellow bone marrow thats stores fat
26
Periosteum
Though fiberous layer surrounding each bone
27
Cartilage
Covers the tips of bones in joints reducing friction and acting as a shock absorber
28
Compact bone
Contains Living cells (osteoblasts) embedded in calcium salts and protein (collagen)
29
Osteocytes
mature osteoblasts that have become trapped within the bone matrix they produced
30
Collagen
Protein in compact bones
31
Where is collagen found
Outer edge of the bone
32
Spongy bone
Makes blood cells and gives strenght to bones and makes them lighter
33
Joint
Where two bones meet
34
Ligaments
Elastic tissues that connect bone to bone
35
3 main types of joints
Immovable
Partially movable
Movable
36
Immovable joint
Bones are fused eg skulls and pelvis
37
Partially movable
Bones slide over each other eg wrist ankle
38
Name the two types of synovial joints
Ball and socket
| Hinge
39
Ball and socket joints
Allows movement in most directions eg hip and shoulder
40
Hinge joint
Allows movement in one place only eg elbow knee finger toe
41
Muscles
Pull on bones and provide movement
42
What are muscles attached to bones by
Tendons
43
When can muscles pull
When they contract
44
Example of a bone disorder
Arthritis
45
Arthritis
A painful disorder where inflammation in one or more joints resulting in swelling and restricted movement
46
Causes of arthritis
Diseases eg gout, tb snd infections of the synovial membranes
47
Prevention of arthritis
Good diet
| Care in footwear
48
Treatment of arthritis
Aspirin
| Replacement
49
Synovial fluid
Produced in movable joints to lubricate and reduce friction
50
Tendons
connect muscle to bone
51
What does muscle contraction need
Energy
52
Red bone marrow makes
Blood cells
53
Yellow bone marrow is
Inactive
54
What is the vertebrae seperated by
Discs of cartiglage
55
Three types of ribs
True false floating
56
Yellow bone marrow stores
Fat
57
Osteoarthritis
Wear and tear of the bone
58
Osteoclasts
Digest bone
59
Osteoblasts
Create/ build bone and deposit it on the outside of the bone
60
Cause of wear and tear of bone
Joints wearing faster than can be replaced
