It can be found at the ends of long bones like the femur, where the bone is actually not solid but is full of holes connected by thin rods and plates of bone tissue. The holes (the volume not directly occupied by bone trabecula) is the intertrabecular space, and is occupied by red bone marrow, where all the blood cells are made, as well as fibrous tissue.
