Where is bone marrow located?

Bone marrow is a spongy substance found in the center of the bones. It manufactures bone marrow stem cells and other substances, which in turn produce blood cells. Each type of blood cell made by the bone marrow has an important job. Red blood cells carry oxygen to tissues in the body.

The bone is made up of compact bone, spongy bone, and bone marrow.

Although extremely porous, spongy bone makes up the majority of interior bone density and is highly vascularized. In adults, all red marrow is found only in the proximal ends of the long bones of the limbs like the femur (as shown in the illustration) and in the breastbone, spine, ribs, shoulder blades, pelvis, and skull.

What makes up the outside of a long bone?

Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone.
