Answer 23

Function: withstanding stress in areas subjected to high impact loads

long bones

Question 24

Spongy/Cancellous Bone

Answer 24

Function: Shock absorption due to its ability to change shape
Honey cone shaped

vertebral

Question 25

Calcium carbonate/calcium phosphate

Answer 25

-stiffness -resistance to pressing and squeezing forces 60-70% bone

Question 26

Collagen fibres

Answer 26

- flexibility - resist pulling and stretching forces - when lost bone becomes brittle - as in aging

Question 27

Wolffs Law

Answer 27

bone adapts to applied loads

Question 28

joint definition

Answer 28

- connection between two or more bones - strands of CT ensure stability and hold joint together - classified by the degree of movement

Question 29

Fibrous Joints

Answer 29

- no movement - absorb shock ex) skull suture

Question 30

Cartilaginous joints

Answer 30

- limited movement, absorb shock | ex) intervertebral discs

Question 31

Synovial Joints

Answer 31

- greatest degree of movement - allows movement ex) hip joint

Question 32

Joint Capsule

Answer 32

- surrounds the joint and provides support | - Lined with synovial membrane that secretes synovial fluid

Question 33

Hyaline Cartilage

Answer 33

-Dense white CT that covers and protects the ends of the articulating bones

Question 34

Ligaments

Answer 34

-support the joint and connect the articulating bones of the joint

Question 35

Uniaxial

Answer 35

movement about one axis | ex) pivot and hinge joint

Question 36

Biaxial

Answer 36

- movement about two perpendicular axis | ex) Condyloid and saddle-shaped

Question 37

Mutliaxial

Answer 37

- movement about all three perpendicular axis | ex) ball and socket, and plane joint

Question 38

Pivot Joint

Answer 38

one bone rotates around one axis, uniaxial | ex)neck
