yellow marrow

bone marrow in which the fat cells predominate in the meshes of the reticular network. See also bone marrow.
One of two types of bone marrow—the other is red—which, like red, contains abundant capillaries, as well as specialised lipid storage tissue but, unlike red marrow, no haematopoietic tissue. Yellow marrow is found in middle of long bones and, in the face of severe blood loss, is converted to haematopoietic red marrow
