Question

the bone having no medullary cavity?​

Answer 1

Answer:

The interior part of the long bone is the medullary cavity with the inner core of the bone cavity being composed of marrow. Flat bones have broad surfaces for protection or muscular attachment. Flat bones are composed of two thin layers of compact bone that surround a layer of cancellous (spongy) bone.

However, the medullary cavity is the area inside any bone (long, flat, etc.) that holds the bone marrow. This area is involved in the formation of red blood cells and white blood cells, and the calcium supply for bird eggshells. The area has been detected in fossil bones despite the fossilization process.

Answer 2

Answer:

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; 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). However, the medullary cavity is the area inside any bone (long, flat, etc.) that holds the bone marrow....
