The medullary cavity is within the diaphysis, which is the long "shaft" of a long bone - not a term for a "long bone". While the diaphysis is mainly consistent of 'compact bone' the medullary cavity is made up of 'soft bone'. 'Hard' and 'Soft' bone are essentially identical, the difference being the physical structure of the minerals created in the organ. |

The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored (which is why medullary cavity is also known as marrow cavity). Located in the main shaft (cortical bone) of a long bone (diaphysis) (consisting mostly of compact bone), the medullary cavity has walls composed of spongy bone(cancellous bone) and is lined with a thin, vascular membrane (endosteum). However, the medullary cavity is the area inside any bone (long, flat, etc.) that holds the bone marrow.[1]
This area is involved in the formation of red blood cells and white blood cells.
