How is the intramembranous bone differ from that of the endochondral bone?
Intramembranous ossification [flat bones] & endochondral ossification [long bones].The essential between them is the presence or absence of cartilaginous phase.Intramembranous ossification occurs when mesenchymal precursor cells proliferate & subsequently differentiate directly into osteoblasts w/c mineralize an immature bone tissue called woven bone,characterize by irregular bundles of randomly oriented collagen fibers & an abundance of partially calcified immature new bone called asteoid.At later stages this woven bone is progressively remodeled to mature,lamellar bone. Endochondral ossification entails the conversion of a cartilaginous template into bone.Mesenchymal cells condense & differentiate into chondrocytes w/c secrete the cartilaginous matrix.This embryonic cartilage is avascular,& during its early development,a ring of woven bone is formed by intramembranous ossification in the future mid shaft area.This calcified woven bone is then invaded by vascular tissue,& osteoclasts & osteoblasts are recruited to replace the cartilage scaffold w/ bone matrix & excavate the hematopoietic bone marrow cavity.
Describe in proper order the events of endochondral ossification?
1. a bone collar is laid down around the diaphysis of the hyaline cartilage model. 2. cartilage in the center of the diaphysis calcifies and then develops cavities. 3. the periosteal bud invades the internal cavities and spongy bone forms. 4. the diaphysis elongates and a medullary cavity forms. 5. the epiphyses ossify.
What is ossification?
Ossification is the process of laying down new bone material by cells called Osteoblasts.
The cell derived from osteoprogenitor cells which produces ossification is the?
Mesenchymal cells
Why are babies mostly cartilage?
Babies are not mostly cartilage, fetuses are. The reason why they are is because they undergo a process known as endochondral ossification. Basically, the fetus creates an outline of what the skeleton should look like with a hyaline cartilage model. Then this cartilage is replaced with the bone cells which create a bone matrix.

What cell responsible for early stage of endocondral ossification?
Osteoprogenitor cells are undifferentiated cells found in the perichondrium. These later become osteoblasts - which secrete osteoid (part of the bone matrix). Chondrocytes are responsible for calcification.

Intramembranous ossification begins with what cells?
Intramembranous ossification begins when osteoblasts differentiate within a mesenchymal or fibrous connective tissue.
Are macrophages responsible for allergic reactions?
No, macrophages are responsible for removing dying or dead cells in the early stages of inflammation. Macrophages essentially ingest these.
The remodeling of bone is a function of which cells?
Ossification.
Definition of ossification?
Ossification (or osteogenesis) in bone remodeling is the process of laying down new bone material by cells called osteoblasts. It is synonymous with bone tissue formation.
What is formed through a process called ossification?
Bone is formed through a process called ossification. Osteoclasts are cells that release an acid which dissolves the collagen and mineral coating. Osteoblasts are cells that lay down new collagen. in ossification the osteoclasts and osteoblasts are involved in breaking down bone.. then forming bone which happens continuously in life
Process of bone formation?
In case of bones you have Diaphysis in the center of bone and Epiphysis at either end. In between you have a plate of cartilage called as Metaphysis. New cells are is formed in this cartilage and get deposition of calcium salt at the end of Diaphysis. There by increasing the length of bone. When maturity age comes, usually by 18 to 20 years, this Metaphysis get ossified and no further growth in length of bones occur. Bone is a living tissue. In which Osteoclast cells continuously remove the bone and Osteoblast cellscontinuously deposit calcium salt in bones. Osteoclast remove the calcium salt and Osteoblasts deposit the calcium salt according to the need of the hour.
