Answer 12

Amphiarthrotic joint

Question 13

What are the 4 structural features of ALL synovial joints?

Answer 13

Fibrous joint capsule (binding tissue) - wall
Synovial membrane - wall paper
Synovial fluid
Articular cartilage: Hyalin

Question 14

What type of tissue is the fibrous joint capsule of synovial joints?

Answer 14

Dense fibrous irregular connective tissue

Question 15

Where is the synovial membrane attached to in synovial joints?

Answer 15

Attached to margins of joint capsule (wall paper)

Question 16

What are the 3 functions of the synovial fluid in synovial joints?

Answer 16

Reduces friction associated with movement
Nourishes Articular cartilage
Evenly distributes pressure across Articular surfaces

Question 17

What are the functions of the Articular cartilage (Hyalin) in synovial joints?

Answer 17

Reduces frictional forces/stress
Deforms when loaded, reducing compressional stress (Stress = force/area)

Answer 18

Fibrocartilage pad
Ligaments

Question 19

What is the Fibrocartilage pad’s functions? (2)

Answer 19

Increase bony fit/congruency
Reduce compressional stress

Intrinsic ligament

Answer 21

Completely within joint

Question 22

Extrinsic ligament

Answer 22

Completely outside of joint

Question 23

Capsular ligament

Answer 24

Bone
Fibrous joint capsule
Synovial membrane
Synovial fluid
Articular cartilage (Hyalin)
Fibrocartilage pads
Intrinsic ligament
