MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.

Detailed explanation-3: -The medullary cavity is the hollow part of bone that contains bone marrow. The bone marrow makes blood cells and stores fat.

Detailed explanation-4: -The medullary cavity is described as a hollow area in the diaphysis part of the bone and is lined by a delicate membrane called endosteum.

Detailed explanation-5: -There are two types of bone marrow: red and yellow. Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow bone marrow is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells.
