Question 1

how does cartilage obtain nutrition and secrete waste

Answer 1

diffusion

Question 2

periosteum covers what and perichondrium covers what

Answer 2

periosteum - covers bone surfaces
perichondrium - covers cartilage surfaces

Question 3

hyaline vs fibrocartilage

Answer 3

hyaline - relatively translucent matrix
fibrocartilage - tough, fibrous tissue matrix

Question 4

osteoblast vs osteoclast

Answer 4

osteoblast - mineralize bone
osteoclast - resorb bone

Question 5

mononuclear cells coat resorbed surfaces so new bone can be attached

Answer 5

cement substance

Question 6

specialized bone matrix, collagen, and ground substance that is subsequently mineralized

Answer 6

osteoid

Question 7

is the periochondrium vascularized or avascularized

Answer 7

vascularized CT w surface growth potential

Question 8

avascular hyalinee cartilage grows interstitially and ossifies to form bone in what zone

Answer 8

zone of endochondral ossification

Question 9

formed by mineralization of hyaline cartilage (endochondral bone formation)

Answer 9

bone spicule

Question 10

produces circulating blood cells, which includes preosteoclasts that form osteoclasts to resorb bone

Answer 10

bone marrow

Question 11

avascular fibrous tissue matrix w no inherent growth potential that is produced by compressively loaded peristudeum

Answer 11

fibrocartilage

Question 12
