Medullary cavity
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.
