Answer 18

3

Question 19

Answer 19

No

Question 20

Give 3 reasons why the hip is an extremely stable joint

Answer 20

-a complete bony socket
-a strong articular capsule
-supporting ligaments

Question 21

How does a meniscus function in a joint? ((Articulardisc))

Answer 21

Menisci may subdivide a synovial cavity, channel the flow of synovial fluid, and allow variations in shape of the articular surfaces. They also act as cushions and shock absorbers

Question 22

Partial or complete dislocation of the acromioclavicular joint is called a..

Answer 22

Shoulder separation

Question 23

How do articular cartilages differ from other cartilage in the body?

Answer 23

Articular cartilages lack a perichondrium and their matrix contains more water than the matrix of other cartilage

Question 24

Differentiate between a slipped disc and a herniated disc

Answer 24

In a slipped disc, the nucleus pulposus does NOT extrude
In a herniated disc, the nucleus pulposus breaks through the anulus fibrosus

Question 25

Explain the characteristic decrease in height with advancing age

Answer 25

In part due to osteoporosis in the vertebrae, and in part a result of the decline in water content of the nucleus pulposus region of intervertebral discs

Question 26

List the 6 different types of diarthrosis, and give an example of each

Answer 26

1. Gliding - clavicle and sternum
2. Hinge - elbow
3. Pivot - atlas and axis
4. Condylar - radius and carpal bones
5. Saddle - thumb
6. Ball and socket - shoulder
