Bone Formation Flashcards
The skeleton is formed from two of the strongest and most supportive tissues in the body
Cartilage and bone
In embryos
The skeleton is made up of hyaline cartilage that is replaced as bone when we become toddlers
Cartilage is mainly at
Bridge of nose,parts of ribs and joints
Most bones develop using hyaline cartilage as their models
Except for flat bones they use fibrous membranes
Bone formation is called
Ossification
Osteoblast
Are bone building cells cartilage is enclosed with real bone in embryo
In order for the bones to increase in length as the infants child
New cartilage is formed continuously on the external face
Mdedullary cavity
Acts like a case in bones to store stuff like red marrow yellow marrow
To maintain proper proportion
Growing bones widen as they lengthen due to osteoblasts add bone matrix and osteoclast removes bone from inner
Osteoblasts form bone matrix and gets trapped
To make osteocytes to keep remoulding

Rickets in children
Are when bones fail to calcify causing bowed legs
Epiphyseal plate
Enable longitudinal growth of bone
