What is the endosteum?

endosteum is a soft, thin connective tissue that lines the inner cavity of long bones. It plays an important role in the healing of fractures by creating new cells necessary for bone fusion. This connective tissue also has hematopoietic potency, which means that it contains hematopoietic stem cells (HSC). HSCs are significant because they can create any type of blood cells.

There are several medical expressions used to describe the bone area that contains an endosteum. These include the medular cavity and the medular membrane. This membrane is located in a diaphyic or a shaft of long bones. The walls of this cavity are made of spongy bone. This is responsible for only 20 percent of the skeleton weight. The medular cavity contains red and yellow bone marrow.

There are three different types of endoste. They are cortical, osteonation and trabecular. The name of each type refers to the area of ​​the inner bone where it is located.

The cortical endoste lines of cortical bones. It also creates the boundaries of the marrow cavity. ThisThe cavity contains yellow bone marrow, which stores fat cells for the body. In the case of extreme malnutrition, these cells are used by the body for fuel.

The

trabecular endosteum covers the inner surface of the trabeculae, which covers the mushroom bones on the shaft. Trabeculae are bony bars that help bone contact without damage. They also contain red pulp that contains HSC and is responsible for creating new blood cells for the body.

osteonal endosteum consists of lining osteon channels. These are in compact bones and are home to bone blood and nerve reserves. They are also known as the Haversian Canals, after the doctor who discovered them.

When an individual is malnourished, the endosteum is reabsorbed by the body. Because it is part of the inner bone, dechytnation results in less thickness and bone density. This reduces the cortical thickness of the bone that is devastating to the body because the cortical bone is the responsibilityScience for many body functions, including storage and release of calcium. It can also reduce weight because the cortical bone is about 80 percent of the human skeleton.

periosteum is the equivalent of the endosteu on the outside of the bone. It is durable and strong. Periosteum is also important in fracture healing because it produces the cells needed to rebuild the bone.
