MICROANATOMY

Detailed explanation-1: -The endosteum is lined by a single thin layer of bone-lining cells (mature osteoblasts) and osteoblasts which form a membrane over endocortical and trabecular bone surfaces to enclose the bone marrow [34].

Detailed explanation-2: -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-3: -The medullary cavity has a delicate membranous lining called the endosteum (end-= “inside”; oste-= “bone”), where bone growth, repair, and remodeling occur. The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri– = “around” or “surrounding”).

Detailed explanation-4: -The periosteum, endosteum and perichondrium are all layers of tissue in and around your bones. The periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal. The endosteum is a membrane that lines the center of your bones that contain bone marrow.
