blood Flashcards
cells that have a clear golgi region next to the nucleus
lymphocyte
Large lymphocytes with azurophilic granules
cytotoxic T cells
cytoskeletal feature of all white blood cells
pseudopodia
3 components of bone marrow
reticular CT stroma, hematopoietic cords, venous sinuses
CFU
colony forming unit: pleuripotent stem cell for all blood cells in marrow. Makes CFC’s. Secretes glycoprotein hormone stimulating factors. Looks like small lymphocyte
CFC
colony forming cell: one for each type of blood cell
the rarest granulocyte in peripheral blood/ bone marrow
basophil
myelopoeisis makes these cell types
monocytes, lymphocytes?, and (leukocyctes) granulocytes : all WBC’s
what cell makes platelets
megakaryocyte
granulocyte with an oval nucleus
myelocyte
granulocyte with a kidney shaped nucleus
metamyelocyte
small dense nucleus and grey cytoplasm
polychromatic eurythroblast
granulotcyte with u-shaped nucleus
neutrophil band form cell
reticulocyte
immature RBC that still contains some rRNA. Only 1-2% of the blood. More reticulocytes= more RBC production
what are the two components of platelets
- granulomere- containing the vasoconstrictor SERATONIN
2. hyalomere- containing thee microtubules that give it its biconcave shape
diapedesis
the squeezing through action of leukocytes past the post capillary venule endothelium
crystalloid core
eosinophil granulocytes. contain MBP (Major Basic Protein) that leads basophils to release heparin and histamine
largest leukocytes
monocytes - progenitors of the mononuclear phagocyte system
sites of hemopoeisis
- yolk sac 2. liver 3. (postnatal) spleen, lymph node, bone marrow, and thymus
what type of reticular fibers are made by reticular cells of bone marrow
type III
where are erythroblasts and megakaryocytes concentrated in the marrow
near the venous sinuses
