What is Bone Resorption and Bone Remodelling
Bone architecture constantly changes based on age, injury, mechanical damages caused due to strain and stress on the body. This continuous process of bone formation and replacing damaged parts by adding new cells is called bone remodelling. Rate and speed of bone remodelling is faster in children of young age and in adults. It slows down with increasing age in older individuals.
Bone Resorption
Bone resorption is a physiological process in which osteoclasts are formed to break down and remove old or damaged bone tissue. Osteoclasts create an acidic environment and secrete enzymes to dissolve the mineral and organic components of bone, releasing minerals like calcium and phosphorus into the bloodstream. This process is tightly regulated by hormones, growth factors, and mechanical stimuli to maintain skeletal health and mineral homeostasis. This process results in formation of small cavities called resorption pits or lacunae.
Bone Anatomy β Functions, and Types
Bones are essential organs of the skeletal system in vertebrates, providing structural support and protection to internal organs. They also facilitate movement, blood cell production, and mineral storage. Bones in the human body are made of bone tissue, cartilage, marrow, blood vessels, and nerves.
Each bone has a specific function and shape. Bone growth and remodeling occur throughout life. These processes are regulated by ossification and bone resorption. Let us discuss bones, their structure, function, and more in detail.
