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.

The first layer of the bone of the skull is the outer table, which is composed of dense, compact bone. This layer provides protection and strength to the skull, forming the outermost part of the cranial vault. Beneath the outer table lies the diploë, a spongy bone layer that contains bone marrow and contributes to the overall lightweight structure of the skull. The inner table, which is the innermost layer, is also made of compact bone and lines the cranial cavity.
The endocardium is the innermost layer of the heart wall.
there are 5 layers of atmosphere.i think trposphere is the innermost layer of the atmosphere
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.
