In adults: Red marrow is found mainly in the flat bones hip bone, breast bone, skull, ribs, vertebrae and shoulder blades In the cancellous (spongy) material at the proximal ends of the long bones femur and humerus. Yellow marrow is found in the medullary cavity the hollow interior of the middle portion of long bones.In a child, all bone marrow is red bone marrow and can be found in nearly all flat and long bones, including the epiphysis and diaphysis.As the child ages the red bone marrow in the diaphysis of the long bones will be replaced with yellow bone marrow.ellow marrow is found in the medullary cavity the hollow interior of the middle portion of long bones.

Diaphysis. The largest part of any long bone is the long cylindrical middle, called the diaphysis. The diaphysis takes the brunt of the force a long bone must support, and is made up primarily of compact bone -- a dense, strong bone composed of minerals, as hard as many types of rock.The diaphysis also has small holes for blood vessels that carry nutrients to the compact bone cells.etaphysis. Between the ephiphysis cap and the long shaft of the diaphysis is a wide section of bone called the metaphysis. The metaphysis transfers load and stress from the joints at the ephphysis into the longer and stronger diaphysis.
