The bones of a human foot

A bone is a rigid organ that constitutes part of the vertebral skeleton. Bones support and protect the various organs of the body, produce red and white blood cells, store minerals, and also enable mobility. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and sizes and have a complex internal and external structure. They are lightweight yet strong and hard, and serve multiple functions. Mineralised osseous tissue or bone tissue, is of two types—cortical and cancellous—and gives it rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels, and cartilage. Bone is an active tissue composed of different cells.

The evil that men do lives after them; The good is oft interred with their bones.
