About Bone Marrow "bone
marrow"
Definition of bone marrow:
Is the inner part of the spongy bone shape and Channel cores in the long bones and consists of Stroma in vain and cells Cells, and its main function the formation of blood cells and put inside the blood vessels.
Bone marrow components:
As mentioned in the definition marrow consists of:
1. Warp (which consists of connective tissue reticular any form of retinal fibers and cells of the retina). Within the warp related to the arteries and veins and many pockets great and thin walls containing cells in the walls stable retinal lined with limits is clear, but when you need separate and turn in the shape of the phagocyte cells become great free travel in the blood. The importance of blood vessels in the warp (ie, vascular medullary) they are configuring the blood cells and regulate the entry of cells into the blood by the body's need as you بمقام refinery to these cells.2. Cells ... Namely:• adipocytes Adipose cells• adult blood cells, no red, white and lymph.• fragrances blood cells, a common cell that generate red blood cells and white, and platelets.• cells represent successive stages of the emergence of red blood cells and white, and platelets.• cells Msoria Plasma cells.• hotbeds of lymphoid tissue.
Bone marrow:
• In the fetus, children and adults up to age 21, there is in all bone marrow bone cavities.• In any adult after the age of 21 years it is:1. Bone cavities and flat surface, a collarbone and sternum and skull, spine and ribs, shoulder and pelvis.2. Major parties round bone Kaazam thigh, leg and arm.
Be and the evolution of bone marrow:
- Consists of bone marrow at the end of the second month of fetal, but its significance start of the fifth month and range up at birth and continue throughout life in the production of blood cells.- During the first seven years of human life there is bone marrow Red (of the many contains the erythroid cells Rouge stages of their formation different) in all cavities bone, then begin to recede from the bones of the parties tyro fingers hands and feet and advanced gradually toward the trunk leaving the place Nkhaaa yellow oily, This change will continue until the age of twenty-first.- The bone in the ribs, sternum, skull, clavicle, vertebral bodies and pelvic bones remains red line throughout life.- Both types of spinal tissue (red and yellow) is able to switch to the other type that when forcing the body to quickly meet the blood for emergency blood loss, the bone turns yellow to red marrow active.
The size of the bone marrow and weight:
- The size of the bone marrow of 3.5-6% of the volume of rights.- And a weight of 1600-3700 g in an adult.
Bone marrow functions:
1. Configure different red blood cells and white, and platelets.2. Organizing the passage of various blood cells and maintaining the ratio in the blood as it does not present in the blood only when needed and incompleteness.3. Responsible for the formation of antibodies within the rest of the centers and the most important immune spleen Spleen and lymphatic system.4. To destroy the blood cells advanced age.5. His bone formation through the demolition of the blanks unnecessary bone and formation of new bone with physical growth and needs.6. Is a repository for important in the formation of iron Hb.7. Contains cells omnivorous (Dermanyssus gallinae).
