www.unomaha.edu ~swick blood.html sickle cell anemia b. leucocytes ۱. white blood cells that can be sub divided into a number of major sub types. ۲. at the light level these sub types are distinguished by their ۱ nuclear and ۲ cytoplasmic structure as characterized by specific staining patterns. ۴ ۱۱ million leukocytes per ml of normal human blood. c. romanovsky stain note that the names of a number of leukocytes are based on their type of staining. d. leucocyte classification systems ۱. two major types of classification are used for leukocytes. b. the second classification system is based on the morphology of the stained nucleus. leukocyte classification systems mononuclear nucleus is not composed of identifiable lobes. nucleus may be irregular. polymorphonuclear nucleus is composed of two or more distinct lobes. nuclear lobes are distinct structures that are connected by a thin bridge of nucleoplasm surrounded by nuclear membrane. e. basic leukocyte cell

pmes polymorphonuclear eosinophils . cytoplasm contains ovoid eosinophilic acidophilic membrane bound granules granules are larger than those of neutrophils granules are lysosomes that contain enzymes that can degrade phagocytosed particles recognize and phagocytose antigen antibody complexes and particles that are associated with these complexes that are formed during an immune response. capable of amoeboid movement may be involved in preventing blood clotting at times when it is best that it not occur. granulocytes eosinophil http www.users.globalnet.co.uk ~aair eosinophils.htm http

leukocytes. have a large irregular lobed nucleus that is often s shaped polymorphonuclear. sometimes called pmbs polymorphonuclear basophils cytoplasm is filled with specifically staining granules larger than those in other granulocytes. granules are membrane bound and contain histamine and heparin that are secreted by exocytosis. histamine causes dialation of blood vessels and in effect makes them leaky. this allows serum proteins such as antibodies to infiltrate into tissues. heparine anticoagulant. have limited capacity for amoeboid movement and phagocytosis. function in allergic reactions and inflammatory response. basophil http www medlib.med.utah.edu webpath hemehtml heme ۵baso.html http www.unomaha.edu ~swick blood.html http pathhsw۵m۵۴.ucsf.edu case۱۷ image۱۷۶.html http

have very little cytoplasm. nucleus is surrounded by a thin halo of blue cytoplasm in stained material ۶ ۸ μm in diameter . these cells are unactivated lymphocytes. two populations one that can become t lymphocytes and the other b lymphocytes. when activated by encounter with foreign antigen presented by a macrophage become large lymphocytes that are capable of mitosis. basic leukocyte cell types agranulocytes large lymphocytes ۱ ۱۴ μm in diameter have more cytoplasm relative to nuclear size mononuclear. b and t lymphocytes cannot be differentiated with the light microscope using standard

www.som.tulane.edu classware pathology krause blood ep.html ۱. hemocytoblast multi potent stem cell that divides to form stem cells for erythrocytes or the various types of leukocytes b. hematopoiesis of erythrocytes ۱. proerythroblast formed from division of hemocytoblast essentially the stem cell for the erythrocyte cell line. divides by mitosis to form many ۲. basophilic erythroblasts starts synthesis of hemoglobin. repeated mitotic divisions to form many ۳. polychromatic erythroblasts more hemoglobin synthesis. repeated mitotic divisions to form many http www.som.tulane.edu classware

developmental cell types as described in text. acute myelogenous myeloblastic leukemia aml ۱. characterized by the presence of lots of myeloblasts undifferentiated granulocyte precursors in the bone marrow and blood. ۲. these malignant cells do not differentiate normally. ۳. the diagnosis of aml is made when over ۳ of the marrow cells are myeloblasts. aml presents clinically with ۱. features of bone marrow failure e.g. anemia infections bruising or bleeding. ۲. leukemic infiltration of organs e.g. central nervous system lymph nodes skin may produce specific signs or symptoms. without
