Bone Marrow Anatomy

Depending on the age and haematological demand of an individual. Progenitor cell stem cell lines in the bone marrow produce new blood cells and stromal cells.

Anatomy Of The Bone

In the body the major function of bone marrow is to produce blood cells.

Bone marrow anatomy. Bone marrow is a semi solid tissue which may be found within the spongy or cancellous portions of bones. The inside of your bones are filled with a soft tissue called marrow. It is also found in the large bones of the arms the humerus and the legs the femur.

Articular cartilage is found on the exterior of the bone and helps to lubricate and provide cushioning for joints. In adult humans bone marrow is primarily located in the ribs vertebrae sternum and bones of the pelvis. Bone marrow biopsy is a commonly performed bedside procedure that aids in the diagnosis and staging of hematological malignancies and benign hematological disorders.

Gross anatomy and histology types of the bone marrow. The shaft of the long bone is the diaphysis and houses yellow bone marrow which mainly functions for fat storage. Bone marrow gross anatomy.

Conversely yellow marrow has all the same constituents as red except that fat cells make up the vast majority with resulting poor vascularity. Some marrow is found in what is called spongy bone. Bone marrow comprises approximately 5 of total body mass in healthy adult humans such that a.

Spongy bone contains red bone marrow which is the site of erythropoiesis. Red bone marrow is where all new red blood cells white blood cells and platelets are made. Red bone marrow also contributes along with the liver and spleen to the destruction of old red blood cells.

In birds and mammals bone marrow is the primary site of new blood cell production or hematopoiesis. Most of the above conditions covered individually in the encyclopedic section. It is generally considered a safe procedure with minimal risks.

Bone marrow a component of the lymphatic system is the soft and flexible tissue in the cavities of bone. Bone marrow is the soft spongy gelatinous tissue found in the hollow spaces in the interior of bonesthe average weight of this tissue is about 4 of the total body weight or 26 kg in an adult weighing 65 kg. Bone marrow also helps to remove old cells from the circulation.

Platelets are small pieces of cells that help you stop bleeding when you get a cut. If you can imagine a sponge the structure of spongy bone is similar. Bone marrow is found in bones such as the sternum breastbone ribs pelvis and skull.

Bone marrow has both a vascular component and a non vascular component. There are two types of bone marrow. In humans the red bone marrow forms all of the blood cells with the exception of the lymphocytes which are produced in the marrow and reach their mature form in the lymphoid organs.

Bone marrow lacks the rigidity of the surrounding bone. It is composed of hematopoietic cells marrow adipose tissue and supportive stromal cells. Clusters of haematopoietic cells known as haematopoietic islands are widely.
