Detailed explanation-1: -Endosteum – membrane that lines the medullary canal and keeps the yellow marrow intact.

Detailed explanation-2: -The medullary cavity has a delicate membranous lining called the endosteum. The outer surface of bone, except in regions covered with articular cartilage, is covered with a fibrous membrane called the periosteum.

Detailed explanation-3: -The endosteum lines the inner bone surfaces and is composed of a single layer of connective tissue that lines the surface of the medullary cavity.

Detailed explanation-4: -The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.

Detailed explanation-5: -The endosteum (plural endostea) is a thin vascular membrane of connective tissue that lines the inner surface of the bony tissue that forms the medullary cavity of long bones. Endosteum covers the inside of bones, and surrounds the medullary cavity.
