The medullary cavity (medulla, innermost part) is the central cavity of
adipose
tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.
Located in the main shaft 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).[1][2]
This area is involved in the formation of
white blood cells, and the calcium supply for bird eggshells. The area has been detected in fossil bones despite the fossilization process.[3]
Intramedullary is a medical term meaning the inside of a bone. Examples include
tumors occurring in some forms of cancer or benign tumors such as an enchondroma
.
