The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity. Located in the main shaft of a long bone (diaphysis) (consisting mostly of compact bone), the medullary cavity has walls composed of spongy bone (can… WebThe function of bone tissue is both supportive and locomotive. Bones not only provide the physical scaffold of the body but enable locomotion by providing attachment sites for muscles, tendons and ligaments. In addition, bones permit motor capability, protect vital organs, facilitate breathing, play a role in homeostasis, and produce a variety of cells in …

WebA long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard compact bone. WebFor example, as osteoblasts lay down new layers on the surface of the shafts of long bones, osteoclasts remove bone from the medullary canal to maintain a constant ratio between the thickness of the bone and the diameter of the bone. Hence, as the outside diameter of the bone gets larger so does the diameter of the medullary cavity. five thirty eight how popular is joe biden

Trabeculae form a mesh-like network of bony spicules of varying size that are aligned along regions of biomechanical stress.
