3-nose cartilage
4-larynx cartilage
5- trachea cartilage
6-skeleton of fetus
7-long bone of epiphysis

Question 3

Structure of hyaline cartilage

Answer 3

1-matrix
2-cartilage cells
3-perichondrium

Question 4

What’s the composition of perichondrium

Answer 4

1- outer fibrous layer
2-blood vessels
3-fibroblast
4-an inner cellular layer

Question 5

What’s difference between inner and outer layer of perichonderium

Answer 5

An outer contain Collagen fiber and inner contain cells such as chondrogenic and chondroblast

Question 6

What’s the functions of perichondrium

Answer 6

Nutrition and repair, growth of cartilage

Question 7

The chondroblast what the place where derived

Answer 7

1-from mesenchymal chondrogenic cells

2-from chondrogenic cells within the inner layer of perichonderium

Question 8

The cells of cartilage what’s contains

Answer 8

Lipid droplets
Glycogen

Question 9

Chondroblast cell’s what’s contains

Answer 9

Contains lipid droplet and glycogen

Question 10

What’s organelles Found in chondroblast

Answer 10

Golgi complex
And endoplasmic reticulum

Question 11

What’s the compound

Answer 11

Proteglycan

Question 12

Intercellular substance is basophilic, true or false

Answer 12

True

Question 13

What’s the types of growth of cartilage

Answer 13

1-interstitial growth

2-appositional growth

Question 14

How the interstitial occurs?

Answer 14

1-chondrocyte division
2-synthesis of matrix
3-expands of cartilage from within

Question 15

How the appositional occurs ?

Answer 15

By differentiation of chondrogenic cell in perichonderium
This types of growth result in the formation of chondroblast and new chondrocyte

False ,
Chondrocyte
