MICROANATOMY

Detailed explanation-1: -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. The walls of the diaphysis are composed of dense and hard compact bone.

Detailed explanation-2: -The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat).

Detailed explanation-3: -The shaft of a long bone is called the diaphysis.

Detailed explanation-4: -The diaphysis plays an essential role in the structural functionality, the transport of oxygen and immune support, and mineral and fat storage. The medullary cavity, housed within the diaphysis, is where blood products, including red blood cells, white blood cells, and platelets, are formed.

Detailed explanation-5: -The correct answer is c-the region of a long bone between the end of the bone (known as the epiphysis) and the shaft (known as the diaphysis) is the metaphysis. The inside of the bone is known as the medullary cavity and is the location of the bone marrow.
