granulocytic series

series /se·ries/ (se´rēz) a group or succession of events, objects, or substances arranged in regular order or forming a kind of chain; in electricity, parts of a circuit connected successively end to end to form a single path for the current.se´rial

erythrocytic series  the succession of morphologically distinguishable cells that are stages in erythrocyte development: proerythroblast, basophilic erythroblast, polychromatophilic erythroblast, orthochromatic erythroblast, reticulocyte, and erythrocyte.

granulocytic series  the succession of morphologically distinguishable cells that are stages in granulocyte development; there are distinct basophil, eosinophil, and neutrophil series but the morphological stages are the same.

lymphocytic series  a series of morphologically distinguishable cells once thought to represent stages in lymphocyte development; now known to represent various forms of mature lymphocytes.

monocytic series  the succession of developing cells that ultimately culminates in the monocyte.

thrombocytic series  the succession of developing cells that ultimately culminates in the blood platelets (thrombocytes).

series [se´rēz]

a group or succession of events, objects, or substances arranged in regular order or forming a kind of chain; in electricity, parts of a circuit connected successively end to end to form a single path for the current. adj., adj se´rial.

erythrocyte series (erythrocytic series) the succession of morphologically distinguishable cells that that are stages in erythrocyte development: in order of maturity, the proerythroblast, basophilic erythroblast, polychromatophilic erythroblast, orthochromatic erythroblast, reticulocyte, and erythrocyte.

gastrointestinal series (GI series) an examination of the upper gastrointestinal tract using barium as the contrast medium for a series of x-ray films; see also barium test. Called also barium meal.

granulocyte series (granulocytic series) the succession of morphologically distinguishable cells that are stages in granulocyte development: in order of maturity, the myeloblast, promyelocyte, myelocyte, metamyelocyte, the band or stab cell, which is the least mature form normally found in the peripheral blood, and the mature segmented (polymorphonuclear) granulocyte. Commitment to one of the granulocyte lines occurs in stem cells before the myeloblast stage is reached; thus there are distinct neutrophil, eosinophil, and basophil series; however, the morphologic stages are the same.

lymphocyte series (lymphocytic series) the succession of developing cells that ultimately culminates in mature lymphocytes. The morphologically distinguishable forms are lymphoblast, prolymphocyte, and lymphocyte.

monocyte series (monocytic series) the succession of developing cells that ultimately culminates in the monocyte. The morphologically distinguishable forms are monoblast, promonoblast, and monocyte.

plasmacyte series (plasmacytic series) a series of morphologically distinguishable cells that are stages in plasma cell development: in order of maturity, the plasmablast (an activated B cell usually referred to as a large lymphocyte or lymphoblast), proplasmacyte, and plasmacyte.

thrombocyte series (thrombocytic series) the succession of developing cells that ultimately culminates in platelets (thrombocytes). The morphologically distinct cell types are megakaryoblast, promegakaryocyte, and megakaryocyte, which fragments to form platelets.

series

a group or succession of events, objects or substances arranged in regular order or forming a kind of chain; in electricity, parts of a circuit connected successively end to end to form a single path for the current.

erythrocytic series

the succession of developing cells that ultimately culminates in the erythrocyte. The morphologically distinguishable forms are pronormoblast (rubriblast), basophilic normoblast (prorubricyte), polychromatophilic normoblast (rubricyte), orthochromatic normoblast (metarubricyte), reticulocyte and erythrocyte.

granulocytic series

the succession of developing cells that ultimately culminates in mature granulocytes (neutrophils, eosinophils, or basophils). The morphologically distinguishable forms are myeloblast, promyelocyte (progranulocyte), myelocyte, metamyelocyte, band granulocyte and segmented granulocyte. Stem cells are committed to become either neutrophils or eosinophils before the myelocyte stage. This may also be true for basophils.

lymphocytic series

the succession of developing cells that ultimately culminates in mature lymphocytes. The morphologically distinguishable forms are lymphoblast, prolymphocyte and lymphocyte.

monocytic series

the succession of developing cells that ultimately culminates in the monocyte. The morphologically distinguishable forms are monoblast, promonoblast and monocyte.

thrombocytic series

the succession of developing cells that ultimately culminates in platelets (thrombocytes). The morphologically distinct cell types are megakaryoblast, promegakaryocyte and megakaryocyte, which fragment to form platelets.
