A bone is a hard organ that forms part of the endoskeleton of vertebrates. Bones function to move, support, and protect the body, produce red and white blood cells and store minerals. Bones come in a variety of shapes and have a complex internal and external structure, allowing them to be lightweight yet strong and hard, while fulfilling their many other functions. One of the types of tissues that makes up bones is the mineralized osseous tissue, also called bone tissue, that gives bones their rigidity and honeycomb-like three-dimensional internal structure. Other tissue types found in bones include marrow, the periosteum, nerves, blood vessels and cartilage.
