endosteumiin
Endosteum is a thin membrane of connective tissue that lines the inner surface of the bony walls of the medullary cavity. It also covers the trabeculae of spongy bone within the bone tissue. The endosteum consists of a single layer of osteoblasts and osteoclasts, along with a small amount of extracellular matrix. Its primary function is to maintain the bone matrix and to participate in bone remodeling. The endosteum plays a crucial role in the growth and repair of bones, facilitating the deposition and resorption of bone tissue. It is also involved in the formation of blood cells within the bone marrow, which is housed in the medullary cavity. The endosteum is a vital component of the skeletal system, contributing to its structural integrity and metabolic functions.
