difference between erythropoiesis and leukopoiesis
The megakaryoblasts divide without cytokinesis to become megakaryocytes, huge cells with a large, multilobed nucleus. Define the following blood disorders and give symptoms. Agranulocytes (monocytes and lymphocytes), like the other blood cell types, derive from CFC-S cells. Erythrocytes sedimentation rate (abbrev.) Your body continually makes new red blood cells throughout your lifetime. Describe the difference between a gene and a codon. Many conditions can impact your bodys ability to make and regulate red blood cells. Return to your list of stages in question 9 and indicate at which stage(s) or between which stages the following events occur: Intense RNA synthesis takes place (IV.B.1 and 2), Cytoplasmic basophilia reaches its peak (IV.B.2 and 3), Hemoglobin synthesis accelerates (IV.B.2), Patches of cytoplasmic acidophilia appear; cytoplasm acquires a grayish tinge (IV.B.3), Hemoglobin synthesis peaks and begins to decline (IV.B.4), Protein (hemoglobin) synthesis ceases (IV.B.5), Cells leave hematopoietic cords and enter sinusoids (IV.B.5), Cells lack nucleus but retain some ribonucleoprotein precipitable with cresyl blue stain (IV.B.5), Remaining organelles are broken down by nonlysosomal enzymes (IV.B.5). Microcytic Anemia or 2. Bone marrow functions. It begins in the yolk sac, a structure that surrounds an embryo at the beginning of pregnancy. Then it is specialized into a unipotent cell and later into a proerythroblast. Explain how it acquires its unusual shape, acquires shape because it loses its nucleus and organelles during maturation. Differentiate between different structural proteins and identify examples of where they are used. The fatty, nonhematopoietic replacement tissue in other bony cavities is termed yellow marrow. Although early normoblasts may divide, erythroid cells lose their ability to do so during this stage, which ends with the extrusion of the pyknotic (degenerated, dead) nucleus. How is it treated? Describe the hormonal control of erythropoiesis and leukopoiesis.
