Bone is not a solid uniform material; it has spaces between the hard elements.
The hard outer layer of the bone is made up of the compact cortical bone tissue that gives bone the hard, white, smooth solid appearance. This is often called 'dense' bone.
The inside of the bone is filled with trabecular bone tissue (cancellous or spongy bone) which has a honeycombed appearance due to its open cell porous network made up of rod and plate elements that give the bone lightness and room for the blood vessels and bone marrow.
The innermost layer is the bone marrow.

Bones are composed of multiple layers, including the periosteum (outer layer), compact bone (dense, strong layer), spongy bone (porous inner layer), and bone marrow (innermost layer where blood cells are produced). These layers work together to provide structure, support, and protection to the body.

The four main layers of bones are the periosteum (outer layer), compact bone (dense and hard layer), spongy bone (porous inner layer), and bone marrow (innermost layer responsible for blood cell production).
