The increase in number of the erythrocytes is called erythropenia.
Normally the reticulocytes are 0,5-1% of erythrocytes number.
The increase in number of the leucocytes is called leucocytosis.
The number of the leucocytes is from 4.109/l to 10.109/l
The number of the blood platelets (thrombocytes) is 20.109/l - 40.109/l
The basophils (basophil granulocytes) are about 4-8% of the total number of leucocytes.
An internal network or reticulum from residual RNA (substnatia granulo-reticulo-filamentosa) is found in:
Monocytes
Reticulocytes
Erythrocytes
Megakarycocytes
The specific granules of neutrophils (polymorphonuclear leucocytes) contain:
Mucopolysaccharide
Peroxidase
Histamine
Hydrolutic enzymes
In which stage of granulocyte development appear their specific granules:
Myeloblast
Promyelocyte
Myelocyte
Metamyelocyte
The lymphocytes posses:
Many-lobed (polymorphous) nucleus
Pale, kidney-shaped nucleus
Dark stained, round nucleus
Pyknotic nucleus
The megakaryocytes are:
Large in size lymphocytes
Large in size erthrocytes
Type of macrophage
Cells which cytoplasm is pinched off as blood platelets (thromocytes)
What cell type releases histamine after stimulation
Neutrophil granulocyte
Eosinophil
Monocyte
Basophil granulocyte
Peculiar to the blood serum is the lack of
Fibrinogen
Albumins
Immunoglobulins
Lypoproteins
The consecutive stages in the erythropoesis are:
Proerythroblast, polychromatic erthroblast, basophilic erthroblast, orthochromatic erythroblast, normoblast
Proerythroblast, basophilic erthroblast, polychromatic erthroblast, orthochromatic erythroblast, normoblast
Proerythroblast, orthochromatic erythroblast, basophilic erthroblast, polychromatic erthroblast, normoblast
normoblast, orthochromatic erythroblast, basophilic erthroblast, polychromatic erthroblast
The blood cells derive from:
Ektoblast
Endoblast
Mesoblast
Mesenchyme
In functional aspect, B-lymphocytes are associated with:
Immune tolerance
Inflammation
Production of anitbodies
Release of cytokines
What of the following is specific for the monocytes:
Kidney-shaped nucleus
Eccentric placed nucleus with heterochromatin arranged in "cartwheel" fashion
Scanty, basophilic stained cytoplasm
Pale, grayish-blue stained cytoplasm
Are cells of the reticuloendothelial (macrofage) system
The blood platelets granules contain
Factors of clotting mechanism
Serotonin
Hydrolytic enzymes
Alkaline phosphatase
What of the following is specific for the common stem cell (hemocytoblast)
Gives rise to all blood cells (pluripotential cell)
Large cell with basophilic cytoplasm and dark stained nucleus
Is progenitor type cell
Arises by mitotic divisions of its own type
Is found in all hemopoietic organs
What of the following is specific for the erythrocyte development (erythropoiesis)
Synthesis and accumulation of hemoglobin
Extrusion of the nucleus
Invagination of the nucleus
Decrease in cell volume
