People are born with only red bone marrow.

The red bone marrow in the middle of the bigger bones is what makes the red blood cells that we need.

In the hollows between the trabeculae is red bone marrow, which produces blood cells.

It is mainly found as the red bone marrow in bones, and is often synonymous with this.

In postnatal birds and mammals (including humans), this usually occurs within the red bone marrow.

Once the fetus is delivered, the formation of blood stem cells in infants shifts to the red bone marrow.

The epiphysis is filled with red bone marrow, which produces erythrocytes (red blood cells).

At this point, the long part of the bone, which started as cartilage, is compact bone with red bone marrow in the center.

Blood vessels grow into the cartilage and bring red bone marrow cells and other bone cells with them.

Osteoclasts follow behind the osteoblasts and break down the spongy bone, making a cavity for red bone marrow to fill.

Red bone marrow is found mostly in the ribs, breastbone, shoulder blades, collarbones, hip bones, skull, and spine.

Cancellous bone is highly vascular and frequently contains red bone marrow where hematopoiesis, the production of blood cells, occurs.

The fibers form a soft skeleton (stroma) to support the lymphoid organs (lymph nodes, red bone marrow, and spleen).

This typically involves using a hollow needle to acquire a sample of red bone marrow from the crest of the ilium under general or local anesthesia.

The presence of red bone marrow is rare in members of Chaetophractus, but widespread in Dasypus novemcinctus osteoderms.

Through this process erythrocytes are continuously produced in the red bone marrow of large bones, at a rate of about 2 million per second in a healthy adult.

He coined the term myelogeneous leukemia, (today's acute myeloid leukemia), and described in 1882 the law of dissemination concerning yellow and red bone marrow.

The diploe houses and protects the red bone marrow only found in hip bones, ribs, sternum, vertebrae, and ends of long bones, in adults.

The red bone marrow is a key element of the lymphatic system, being one of the primary lymphoid organs that generate lymphocytes from immature hematopoietic progenitor cells.

Reticulocytes develop and mature in the red bone marrow and then circulate for about a day in the blood stream before developing into mature red blood cells.

Yellow bone marrow makes up the majority of bone marrow stroma, in addition to smaller concentrations of stromal cells located in the red bone marrow.

Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy bone) which contains red bone marrow.

These bones are composed of two thin layers of compact bone enclosing between them a variable quantity of cancellous bone, which is the location of red bone marrow.

The recommendation by SEAC, the British scientific advisory committee, has resulted in new findings about the infectiousness of certain nervous tissue along the spinal column and of red bone marrow.

It forms a labyrinth-like stroma (literally, "bed or "mattress"), or internal framework, that can support many free blood cells (large lymphocytes) in lymph nodes, the spleen, and red bone marrow.
