What is Bone?

The bone is a rigid structure formed of an organic part i.e. connective tissue made up of collagen fibrils and an inorganic part i.e. hydroxyapatite and a very small amount of water. The bone has different structural parts such as compact bone tissue, spongy bone tissue, bone marrow, epiphyseal line, and network of blood vessels.

Bone Definition: A bone is a rigid, mineralized organ that forms the major part of the vertebrate skeletal system.

Bone Anatomy – 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.

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....

Conclusion – Bone Anatomy – Functions and Types

The bone is made up of various cell types viz. Osteoblasts, osteoclasts, osteocytes and bone lining cells. Each type of bone cell has a specific role in bone formation, damage repair, allowing cell to cell communication, and Calcium mineral deposition. Bones are constantly changing. This process is called Bone remodelling. The factors influencing these changes are age, sex, pressure, stress and strain on bones. The physiology of the body also contributes to changes in bone architecture. The key role in bone remodelling is played by bone cells, Vitamin D, and parathyroid hormones....
