bone cartilage

Question 1

perchondrium

Answer 1

double layer connective tissue sheath covering cartilage

Question 2

perichondrium outer layer made of

Answer 2

dense irregular connective tissue with fibroblasts

Question 3

perichondrium inner layer made of

Answer 3

more delicate, few fibers and contains chondroblasts

Question 4

blood vessels and nerves relationship to perichondirum

Answer 4

penetrate outer layer, but do not go into cartilage matrix, so chondrocytes get to nutrition by diffusion

Question 5

articular cartilage

Answer 5

hyaline cartilage that covers ends of bones at join sites,
NO perichondrium, blood vessels or nerves

Question 6

two types of cartilage growth

Answer 6

appositional
interstitial

Question 7

appositional growth

Answer 7

chondroblasts in perichondrium add new cartilage to outside edge of existing cartilage

Question 8

interstistial growth

Answer 8

chondroCYTES in existing tissue divide and add matrix between existing cells

Question 9

cartilage matrix contains

Answer 9

collagen–provides strength
proteoglycans–makes cartilage resilent by trapping water

Question 10

most bones in the body start out as

Answer 10

hyaline cartilage

Question 11

Answer 11
