Commentary

Bone marrow the light tissue interior a few of your bones, similar as your hip and thigh bones. It contains stem cells. The stem cells can create into the red blood cells that carry oxygen through your body, the white blood cells that fight diseases, and the platelets that offer assistance with blood clotting.

Structure

There are six main types of bones

• Long

• Short

• Flat

• Sesamoid

• Irregular

• Sutural

Inside these common bone sorts, there are two different bone structures cortical and trabecular bones. Approximately 80 of the bones within the body are cortical bones. These bones are the foremost strong and thick, but play a minor portion in digestion system.

Trabecular bones are fair 20 of the bones within the body but perform a have metabolic capacities.

Bone marrow is found within trabecular bones. Bone marrow is considered the fourth biggest organ within the body by weight.

Bone gist itself is a spongy, jelly- alike material found in the center of bones, in a space called the medullary cavity. The cavity is surrounded and defended by a hard layer called the periosteum, which must be punctured or penetrated during a bone marrow biopsy.

All sorts of hematopoietic cells, counting both myeloid and lymphoid lineages, are made in bone marrow; still, lymphoid cells must move to other lymphoid organs (e.g. thymus) in arrange to total development.

Types of bone marrow

There are two types of bone marrow red bone marrow (myeloid tissue) and yellow bone marrow (adipose tissue).

Red bone marrow

The three types of blood cells formed from the stem cells Red bone marrow is primarily found in the medullary cavity of flat bones similar as the sternum and pelvic girdle. This sort of bone marrow contains hematopoietic stem cells, which are the stem cells that form blood cells. Hematopoietic stem cells can turn into three sorts of blood cells, all of which have vital capacities that offer assistance keeps a individual alive and healthy. The three sorts of blood cells shaped from the stem cells inside red bone marrow are

• Red blood cells – Transports oxygen all through the body

• White blood cells make a difference fight diseases inside the body Platelets Anticipates intemperate bleeding by making a difference blood to clot after damage.

Yellow bone marrow

The another sort of bone marrow found within the body is yellow bone marrow, which gets its name from its tall attention of fat cells, which show up yellow in colour. This type of bone marrow can be found in the medullary cavity in the shaft of long bones and is frequently girdled by a layer of red bone marrow. Yellow bone marrow contains mesenchymal stem cells (bone marrow stromal cells), which produce cartilage, fat and bone. Yellow bone marrow also aids in the storehouse of fats in cells called adipocytes. This helps maintain the right environment and provides the food that bones need to function.

Associated Conditions

Bone marrow has a lot of important functions in the body, and when there's a problem with the product of or function carried out by bone marrow, the effects are wide-ranging. Red blood cells–Transports oxygen all through the Here are a few of the issues that can arise inside, as a result of issues with, bone marrow

Leukemia: It is a cancer of the blood, where the bone gist produces abnormal white cells.

Aplastic anaemia: In this disease, the bone marrow doesn't produce red blood cells.

Myeloproliferative clutters: These incorporate incessant myelogenous leukemia (CML), polycythemia vera, essential myelofibrosis, essential thrombocytopenia, chronic neutrophilic leukemia, and chronic eosinophilic leukemia. These infections all affect the production of white blood cells, red blood cells, or platelets.

Carcinoma Lymphoma: It is a cancer of the immune cells that begins in the lymphocytes.
