Physiological bone resorption is an integral part of bone functioning, while the bone is constantly growing thanks to two processes — breakdown and formation of bone tissue. [23] Locally, it could be manifested in tooth eruption when the movement of a tooth follicle is followed by an active resorption of jaw bone tissue.
The osteoclast disassembles and digests the composite of hydrated protein and mineral at a molecular level by secreting acid and a collagenase, a process known as bone resorption. This process also helps regulate the level of blood calcium. Osteoclasts are found on those surfaces of bone that are undergoing resorption. On such surfaces, the ...
Bone tissue is removed by osteoclasts, and then new bone tissue is formed by osteoblasts. Both processes utilize cytokine (TGF-β, IGF) signalling.In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
The bone formation portion (σ f) of the bone remodeling period is calculated as follows: [5] = in which MWT refers to the mean wall thickness of the completed bone unit and M f refers to the prevailing mean effective bone appositional rate. In other words, what this formula means is that the bone remodeling period is equivalent to the ...
ON is first characterized by pyknosis of nuclei, followed by hollow osteocyte lacunae. Capillary revascularization and reactive hyperemia slightly take place at the periphery of the necrosis site, followed by a repair process combining both bone resorption and production that incompletely changes dead with living bone.

Resorption is the absorption of cells or tissue into the circulatory system, usually by osteoclasts. [1] Types of resorption include: Bone resorption; Herniated Disc Resorption; Tooth resorption [2] Fetal resorption; Blood resorption
