WebWolff's law. Wolff's law, developed by the German anatomist and surgeon Julius Wolff (1836–1902) in the 19th century, states that bone in a healthy animal will adapt to the loads under which it is placed. [1] If loading on a particular bone increases, the bone will remodel itself over time to become stronger to resist that sort of loading. Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation. There are two processes resulting in the formation of normal, healthy bone tissue: Intramembranous ossification is the direct laying down of bone into the primitive connective tissue (mesenchyme), while endochondral ossification involves cartilage as a precursor.
WebNational Center for Biotechnology Information WebEtiology and Pathophysiology a. Osteoporosis is caused by an imbalance between bone formation and resorption, resulting in a net loss of bone mass and density. b. The primary cell types involved in bone metabolism are osteoblasts, which build new bone tissue, and osteoclasts, which break down old bone tissue. c.

WebBone spurs, or osteophytes, are smooth, bony growths, usually near joints. They develop over time in patients with arthritis or joint damage. The feet, hands, knees and spine often develop bone spurs. A healthy lifestyle can delay symptoms like pain, stiffness and limited motion. Medications, physical therapy and surgery may help.
