The endosteum is the lining around the innermost layer of the bone. It is not the layer where bone marrow is stored.

The osteogenic bone cell is not a layer of the bones. Osteogenic cells is another term for bone marrow.
- Medullary cavity
The medullary cavity is the innermost layer of the bones. It is the location where bone marrow is stored.
The skeletal bones can be categorized and classified in several ways.
Bones typically have three layers: the periosteum, the endosteum, and the medullary cavity. The medullary cavity is the innermost part of the bone. Its primary function is the storage of bone marrow.
