Study Notes
Bone Marrow Structure and Function
- Red (hematopoietic) bone marrow is primarily found in the cavities of bones such as the pelvis, ribs, and sternum in adults.
- Yellow bone marrow is primarily found in the shafts of long bones in adults.
Hematopoietic Tissue
- Hematopoietic tissue produces all blood cells except lymphocytes.
- Hematopoietic tissue is responsible for producing red blood cells, white blood cells, and platelets.
Megakaryocytes and Platelets
- Megakaryocytes undergo endomitosis, a process in which the nucleus undergoes multiple rounds of DNA replication without cell division.
- Megakaryocyte nuclei can have up to 64 copies of normal DNA.
- Platelets are produced from megakaryocytes.
- The main function of platelets is to form blood clots and stop bleeding.
Lymphocyte Development
- B lymphocytes develop in the bone marrow.
- T lymphocytes develop in the thymus.
Hematopoietic Stem Cells
- Hematopoietic stem cells give rise to all types of blood cells, including red blood cells, white blood cells, and platelets.
Bone Marrow Components
- Bone marrow stroma consists of various components, including fat cells, macrophages, and reticular cells.
- Bone marrow also contains sinusoids, which are special blood vessels.
Erythrocytes
- The main function of erythrocytes (red blood cells) is to carry oxygen from the lungs to the body's tissues.
- Erythrocytes have no nucleus in their mature form.
- The developmental stages of erythropoiesis are: proerythroblast, basophilic erythroblast, polychromatic erythroblast, orthochromatic erythroblast, reticulocyte, and mature erythrocyte.
Granulocytes
- Granulocytes are a type of white blood cell that has a multilobed nucleus.
- Granulocyte maturation in the bone marrow takes 10-14 days.
- The function of granulocytes is to engulf and digest foreign particles and bacteria.
Agranulocytes
- Agranulocytes are a type of white blood cell that lacks granules in their cytoplasm.
- The function of agranulocytes is to produce antibodies to fight infections.
