Ossification

Question 1

Osteogenesis/ ossification of bone

Answer 1

Bone tissue formation

Question 2

Osteogenesis/ ossification of bone stages

Answer 2

Bone formation (2 month of development)
Postnatal bone growth (until early adulthood) 
Bone remodeling and repair (life long)

Question 3

Two types of ossification

Answer 3

Intramebraneous ossification

Endochondral ossification

Question 4

Intramembraneous ossification

Answer 4

Membrane bone develops from fibrous membrane

Forms most flat bones

Question 5

Intramembraneous ossification step one

Answer 5

Ossification center appear in fibrous connect tissue membrane

Question 6

Intramembraneous ossification step two

Answer 6

Bone matrix (osteoid) is secretes within fibrous membrane and calcified

Question 7

Intramembraneous ossification step 3

Answer 7

Woven bone and periosteum form

Question 8

Intramembraneous ossification step four

Answer 8

Lamellar bone replaces woven bone, deep to periosteum. Red marrow appears

Question 9

Endochondral ossification

Answer 9

Cartilage bone forms by replacing hyaline cartilage
Uses hyaline cartilage as model
Forms most of the rest of the Skelton

Question 10

Endochondral ossification step one

Answer 10

Bone collar forms around hyaline cartilage model

Question 11

Endochondral ossification step two

Answer 11

Cartilage in the center of the diaphysis calcified and develops cavities

Question 12

Endochondral ossification step 3

Answer 12

Periosteum bud invades internal cavities and spongy bone begins to form

Question 13

Endochondral ossification step 4

Answer 13

Diaphysis elongates
Medullary cavity forms
Secondary ossification centers appear in epiphysis

Question 14

Endochondral ossification step 5

Answer 14

Epiphysis ossify

Question 15

At the end of endochondral ossification where is hyaline cartilage

Answer 15

At end hyaline cartilage remains only in epiphyseal plates and articulate cartilage
