Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2]. Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4].

STRUCTIRE OF A BONE

FUNCTION OF A BONE

Bones have many functions. They support the body structurally, protect our vital organs, and allow us to move. Also, they provide an environment for bone marrow, where the blood cells are created, and they act as a storage area for minerals, particularly calcium.

At birth, we have around 270 soft bones. As we grow, some of these fuse. Once we reach adulthood, we have 206 bones.

The largest bone in the human body is the thighbone or femur, and the smallest is the stapes in the middle ear, which are just 3 millimeters (mm) long.

Bones are mostly made of the protein collagen, which forms a soft framework. The mineral calcium phosphate hardens this framework, giving it strength. More than 99 percent of our body’s calcium is held in our bones and teeth.

Bones have an internal structure similar to a honeycomb, which makes them rigid yet relatively light.
