Fetal bone Flashcards
what is replaced by bone
the cartilage
In embryos the Skelton is primarily
hyaline cartilage
how many stages have ossification
6
steam cells called mesenchymal cell cluster
Development of cartilage model
differentiate into clusters of,…
chondroblast that secret the hyaline cartilage
growth of cartilage model
cartilage grows in length and width
Growth within
intersitial growth
growth at the outer surface
appositional growth
osteoblast begin to form the periosteum of the bone
development of the first ossification center
osteoclast break down the inner part of the bone matrix
development of the medullary cavity
development of the secondary ossification center
osteoblast build up the periosteum and endoestuem of the bone
formation of the articular cartilage/ epiphyseal plate
-hyaline become articular cartilage on the epiphysis and remains at the epiphyseal plate where growth occurs
