Question 1

types of joints

Answer 1

fibrous, cartilaginous, synovial

Question 2

types of synovial joint

Answer 2

hinge
pivot
saddle
condylar
plane
ball and socket

Question 3

what type of collagen in hyaline cartilage

Answer 3

type 2

Question 4

fibrocartilage looks like

Answer 4

lines of collagen fibres. makes it thick

Question 5

hyaline cartilage looks like

Answer 5

still contains collagen fibres just cant see
not as much as fibrocartilage

Question 6

what does synovium do (membrane)

Answer 6

direct exchange of oxygen, carbon dioxide and metabolites between blood and synovial fluid

rich capillary network
no epithelial lining

Question 7

type A synoviocytes

Answer 7

look like macrophages
remove debris
contribute to synovial fluid production

Question 8

type B synoviocytes

Answer 8

main producer of synovial fluid
fibroblast like

Question 9

effect of ageing on joints

Answer 9

thinning of articular cartilage
water content in cartilage decreases
concentration of key molecules decreases
increased collagen cross linking due to formation of advanced glycation end- products

increased stiffness and brittleness
reduced shock absorption
less protection of articular surfaces and increased risk of damage
