Bone formation and g

QuestionAnswer
Ossification (osteogenesis) Process of bone formation -begins in embryo and continues thru childhood
Calcification Deposit of clacium salt (occurs during bone formation)
What are the two forms of ossification? Endochondral-hyaline cartilage model Intramembranous ossofication- mesenchymal model
What age do bones stop growing? 25
Endochondral ossification -how most bones form -developed inside hyaine cartilage
Primary ossofication center -cartilage is surrounded by perichodrium with immature chondeoblasts -cartilage is gradually replaced by bone
Epiphyseal closure Puberty affecting cartilage growth and upping osteblast
Articular cartilage this cartilage prevents damaging the joint from home to bone contact
Interstitial growth Growth in length
Epiphyseal closure Completion of bone growth
Zone of reserve cartilage Cells are not directly involved in bone growth
Zone of proliferation Actively dividing chondeoblasts, push cells into next zone (elongate bone)
Zone of hypertrophy and maturation Mature chondrocytes in lacuna, actively producing ECM
Zone of calcification Chondrocytes for as ECM calcified and nutrients are cut off
Zone of ossification Osteoblasts and osteoclasts present, replace calcified tissue with new osteoid matrix
Appositional growth Growth in width/circumstance -thicken/strengthens -deepest layers become replaces by osteons -during process, osteoclasts slowly remodel and remove bone matrix at inner surface of bone
Intramembranous ossification (dermal ossification) -occurs in dermis -produces dermal bones like cranial, lower jaw, collar bones
How are areas of spongy bone remodeled? Using diploƫ and thin covering of compact bone
Hope does blood supply get to bones? -internal artery and veins -pass through nutrient foramina in diaphysis
What supplies blood to epiphyseal cartilages where bone growth occurs? Metaphyseal vessels
What supplies blood to superficial osteons and secondary ossification centers? Peiosteal vessels
