Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.\n\n2. The tissue occupying the spaces of bone. It consists of blood vessel sinuses and a network of hematopoietic cells which give rise to the red cells, white cells, and megakaryocytes.\n\n3.
