Bone marrow : bone marrow structure-role of the bone marrow


 What Is Bone Marrow?

Bone marrow is a tissue found in the center of most bones. This tissue contains stem cells that develop into the different cells of the blood, including white blood cells, red blood cells, and platelets. In people with certain blood disorders, a bone marrow transplant may be necessary. A bone marrow transplant is a procedure in which faulty bone marrow is replaced with healthy bone marrow from a donor.

What Is Bone Marrow
Bone Marrow

bone marrow structure

  • The bone marrow is the tissue where hematopoiesis occurs. Hematopoiesis is the process of producing red blood cells, white blood cells, and platelets in the marrow. The hematopoietic stem cells (HSCs) are responsible for the production of all of these blood cell types. There are two types of bone marrow: red marrow and yellow marrow.

  • Bone marrow is the spongy tissue in the cavities of the long bones in the body. In children, the marrow in most bones is active hematopoietic tissue producing not only red blood cells (erythrocytes) but also most of the lymphocytes. With age, the production of erythrocytes gradually shifts to the spleen and lymph nodes. Lymphocytes are cells of the immune system that defend the body against infection and disease.

There are two sorts of bone marrow to your frame, which might be characterized through their color. Your body holds just under 6 lbs. (about 2.Five kg.) of crimson and yellow bone marrow.

  • Red: Red bone marrow produces blood cells (hematopoiesis). Stem cells for your purple bone marrow (hematopoietic stem cells) create purple and white blood cells and platelets, all of which can be components of your whole blood.

  • Yellow: Yellow bone marrow shops fats. There are two sorts of stem cells in yellow bone marrow (adipocytes and mesenchymal stem cells). These cells maintain fat for energy manufacturing and broaden bone, cartilage, muscle groups and fat cells on your frame.

  1. There are three components to the anatomy of your bones: compact bone, spongy bone and bone marrow. Compact bone is the robust, outer layer of your bones. Spongy bone makes up the ends of your bones. Bone marrow is within the center of most bones and in the end of spongy bones on your body. Bone marrow and blood vessels fill cavities to your bones, where they save fats and stem cells and convey blood cells that make your entire blood.

  2. Bone marrow is a spongy, gentle tissue that resembles a jelly or jam that you would spread on toast. It is available in  colors, crimson and yellow. Bone marrow fills the cavities of your bones and holds cells that create purple and white blood cells and platelets, which make whole blood. The coloration of red bone marrow is the end result of pink blood cell manufacturing.

  3. Bone marrow is made from stem cells. These stem cells make pink bone marrow, which creates blood cells and platelets in your blood. Yellow bone marrow consists ordinarily of fat and stem cells that produce bone and cartilage on your frame.

What is the role of the bone marrow?

  • The bone marrow is a spongy tissue found within the medullary cavity of long bones. It is responsible for producing blood cells, storing minerals, and Fat metabolism. In children, the bone marrow is primarily red, meaning that it is mostly involved in hematopoiesis, or the production of blood cells. As we age, the bone marrow becomes more yellow in color as fat cells begin to dominate.

  • Bone marrow makes almost all the components of your blood. It's answerable for creating billions of purple blood cells each day, alongside white blood cells and platelets. Bone marrow additionally stores fat that will become energy as wished.

bone marrow symptoms

May be asymptomatic or have nonspecific symptoms. In later disease stages, they may have fatigue, malaise, weight loss, anorexia, myalgias, arthralgias, or fever. Patients with active disease may also report bone marrow symptoms such as: easy bruising, epistaxis, and bleeding gums due to thrombocytopenia; or fatigue, anemia, and pallor secondary to erythrocytosis. May also present with neurologic manifestations and organomegaly.

Common symptoms of bone marrow conditions include:

  • Bleeding effortlessly,

  • Bruising.

  • Fatigue.

  • Frequent infections.

  • Muscle weak spot.

What affects the health of the bone marrow?

The health of bone marrow is a complicated affair. A variety of factors, both internal and external can contribute to its well-being or lack thereof. The most important internal factors are the age and health of the individual cells that make up the bone marrow. External factors include diet, stress levels, and exposure to toxins and infections.

There are many things that can affect the health of the bone marrow. Things like chemotherapy and radiation can harm the bone marrow and make it difficult for it to produce the blood cells that the body needs. Other conditions, such as certain types of cancer, can also affect the bone marrow.

Since bone marrow is the inspiration for the creation of blood cells, blood-associated situations frequently are the end result of abnormally functioning bone marrow. These conditions include:

  • Multiple myeloma: Your frame produces cancerous plasma cells to your bone marrow.

  • Aplastic anemia: Your bone marrow doesn’t produce sufficient blood cells.

  • Polycythemia vera: Your body makes too many crimson blood cells, which causes your blood to thicken.

  • Myelodysplastic syndromes: A group of illnesses characterized by means of your bone marrow no longer generating enough healthy blood cells (anemia).

Maintain healthy bone marrow

The bone marrow is essential for the production of red blood cells, white blood cells, and platelets. In order to maintain a healthy bone marrow, you need a well-balanced diet that includes plenty of fruits, vegetables, and whole grains. You should also avoid processed foods, sugary drinks, and cigarettes. Exercise is also important for maintaining a healthy bone marrow.

You can hold your bone marrow wholesome by:

  • Eating a weight-reduction plan wealthy in protein (lean meats, fish, beans, nuts, milk, eggs).

  • Taking vitamins (iron, B9, B12).

  • Treating clinical conditions in which bone marrow abnormalities are a facet impact.

Bone marrow transplant (BMT)

Bone marrow transplant (BMT) is a unique therapy for sufferers with positive cancers or other diseases. A bone marrow transplant includes taking cells which might be usually observed within the bone marrow (stem cells), filtering those cells, and giving them back either to the donor (affected person) or to some other man or woman.
