The endosteum (pl.: 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. [1] [2] This endosteal surface is usually resorbed during long periods of malnutrition, resulting in less cortical thickness. [citation needed]

May 1, 2023 · Periosteum and endosteum contain cells (osteoblasts, osteoclasts, and osteoprogenitor cells) required for bone development and remodeling of the bone. Understanding the histology of the endosteum and periosteum will …

Oct 30, 2023 · The endosteum refers to a layer of connective tissue that line the inner surfaces of bones including both the medullary (marrow) cavity of compact bone and the thin spicules or trabeculae of cancellous (spongy) bone.

Sep 3, 2017 · What is Endosteum? Endosteum is a thin, soft, connective tissue, lining the cavity of long bones like Humerus and Femur. It acts as a coating for the inner compact bone and the trabeculae of the spongy tissue.

Jan 21, 2025 · Endosteum is a thin, vascular membrane lining the inner surface of bones. It covers the medullary cavity, trabeculae of spongy bone, and the inner surfaces of the central canals of compact bone.

The endosteum is the tissue lining all inner aspects of the bones, including the medullary cavity (Dorland, 2011). The endosteum is a thin osteogenic layer that is lined with osteoblasts and precursors to osteoblasts. In times of inactivity, these cells are flat and are not easy to distinguish from each other.

The endosteum is a thin membrane of connective tissue that lines the inner surfaces of bones. It is primarily composed of osteoprogenitor cells, which are bone stem cells. The endosteum is found lining the medullary cavity of long bones, as well as the trabeculae of spongy bone.

What Is Endosteum? Endosteum is a structure found on the inner surface of the bone. It is a membrane layer that coats the medullary cavity, bony trabeculae; the spongy part of the bone, inner walls of the compact bones and haversian canals. 1
