ANATOMY

Detailed explanation-1: -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.

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 endosteum is a membrane that lines the center of your bones that contain bone marrow. The perichondrium is very similar to the periosteum. It covers the cartilage on the ends of your bones.

Detailed explanation-5: -it is an osteogenic membrane: a delicate connective membrane containing mainly osteocytes and osteoclasts. Endosteum covers all the bones’ inner cavities that contain marrow and/or blood vessels.
