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. There are two processes resulting in the formation of normal, healthy bone tissue: ...

Increase in circumference of the bone shaft is achieved by formation of new bone on the outer surface of the cortical bone. Bone modelling. Modeling is when bone resorption and bone formation occur on separate surfaces (i.e. formation and resorption are not coupled). An example of this process is during long bone increases in length and diameter.

Bone Development | Boundless Anatomy and Physiology

The formation of bone during the fetal stage of development occurs by two processes: intramembranous ossification and endochondral ossification. Secondary ossification occurs after birth and forms the epiphyses of long bones and the extremities of irregular and flat bones.

Bone Resorption Inhibitors

The bisphosphonates bind calcium and are rapidly taken up in bone matrix where they suppress osteoclastic activity and change the balance between bone resorption and bone formation, thus increasing bone mass. The bisphosphonates have been shown to be effective in treating malignant hypercalcemia and in preventing and treating osteoporosis.

Active sites of bone formation are characterized by large basophilic osteoblasts. The osteoclast is usually found in depressions (Howship's lacunae) at the surfaces of bony tissue and is associated with bone resorption; it is a large multi-nucleated cell derived from blood monocytes.

Bone Formation Ossification, Bone Resorption Removal ...

Osteoporosis is caused by an imbalance in the bone remodeling (rebuilding) process. This process is made up of two components: the bone formation ossification and the bone resorption (removal) processes. Usually, the removal and formation of bone are in perfect balance and skeletal strength and integrity is maintained.

2. Resorption-During resorption, osteoclasts invade the bone surface and erode it, dissolving the mineral and the matrix.. Resorption Complete-A small cavity is created in the bone surface – resorption is complete.. Formation Repair-Bone forming cells called osteoblasts begin to fill in the cavity with new bone..

Bone Deposition and Resorption

The formation and resorption of bone occur constantly at rates determined by the relative activity of osteoblasts and os-teoclasts. Body growth during the first two decades of life occurs because bone formation proceeds at a faster rate than bone resorption. By ageor, the rate of bone resorption often exceeds the rate of bone deposition.

Biochemical Pathways

Bone remodeling is a naturally occurring process in which old bone tissue is removed and replaced with newer bone tissue. "The speed or rate of bone resorption (removal) is controlled by how fast the osteoclasts (cells that break down old bone tissues) are formed and matured" ( "Bone Formation Ossification, Bone Resorption Removal Information").

6.Bone Formation and Development

All bone formation is a replacement process. Embryos develop a cartilaginous skeleton and various membranes. During development, these are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue.

Endochondral bone formation. To obtain clues as to the origin of the bone-forming cells, the lateral “walls” of marrow tunnels were examined in great detail. In the bones from younger chick embryos, the majority of edges appeared to be “quiescent,” i.e., there was no evidence for either bone formation or resorption.

Abnormal Excess Bone Growth in Heterotopic Ossification

Heterotopic ossification occurs when the body gets signals mixed up, and bone cells begin to create new bone outside of the normal skeleton. The body constantly makes new bone to replace bone within the skeleton. When fractures occur in the bone, new bone is formed to heal the damaged bone.
