Bone formation is called |
Ossification |
|
|
2 types of ossification and what bones they form |
1. Intramembranous ossification- forms skull, mandible, collarbone (Deposit bone on embryonic mesenchyme) 2. Endochondral- forms all other bones (Osteoblasts deposit bone on cartilage) *Cartilage does not turn into bone!!!! |
|
|
Epiphyseal plate= |
Growth plate (cartilage cells called chondrocytes) |
|
|
Interstitial bone growth |
Growth in length, only occurs at epiphyseal plate!! Occurs in children |
|
|
Appositional bone growth |
Growth of bone in width Occurs in children AND adults |
|
|
Epiphyseal line |
After hitting end of growth, in the epiphyseal plate the chondrocytes will stop dividing and get replaced by bone |
|
|
Growth grooming is made where? |
Pituitary gland in brain |
|
|
Gigantism & Acromegaly |
Gigantism- growth of bones in length- chondrocytes keep dividing rapidly until epiphyseal plate tunes to line. Acromegaly- causes rapid growth in width after epiphyseal plate has turned to line Both are results of issues of growth horomones |
