Steps of Ossification:

Step 1:

Definition
Cartilage Model: hayaline catilage forms smooth bony shape
Term

Steps of Ossification:

Step 2

 

Definition
Bony Collar: the cartilage is replaced by bone
Term

Steps of Ossification:

Step 3

Definition
Primary ossification center: center of diaphysis expands because more osteoblasts becomes osteocast
Term

Steps of Ossificaiton:

Step 4

Definition
Medullary Cavity: This forms after blood vessel invade
Term

Steps of Ossificaiton:

Step 5

Definition
Secondary Ossification Center: The ends of each epiphysis start to form.
Term

Steps of Ossification:

Step 6

Definition
Growth Plate: Starts to become visiable, and Osteoclast and Osteoblast invade
Term

Steps of Intramembranous Ossification:

Step 1:

Definition
Sub-dermal: tissue forms a layer mesenchyme dermis
Term

Steps of Intramembranous Ossification:

Step 2:

Definition
Differentiate: from mesenchyme into osteoblast to osteiod
Term

Steps of Intramembranous Ossification:

Step 3:

Definition
Osteiod & Calcification: crystalites trap osteoblasts that become osteocytes
Term

Steps of Intramembranous Ossification:

Step 3:

Definition
Blood Vessel invasion
Term

Steps of Intramembranous Ossification:

Step 5:

Definition
Outer layer remodeling converts: lamellae with osteons
Term
Healing of fracture
Definition

1. Hematoma=blood clot

2. soft callus=blood gets replaced by hyaline cartilage

3. Bony callus= replaced cartilage with forms of osteoblast

4. Remodeling= build new bone; take away the old.
