17 Cards in this Set

  • Front
  • Back
Platelets
-Cell fragments
-Not cells
-Purple, granular cytoplasm
-No nucleus
-Network of microtubules
-Granuels only seen on EM
Lymphocytes
-Nucleus w/ dark chromatin
-Small ring of basophilic cytoplasm
Monocyte
-Largest blood cell
-Nucleus peanut shaped, not multilobed
-May have many nuclei
-Have more cytoplasm than Lymphocytes
-Upon entering CT, become macrophages
Neutrophil
Granulocytes
-Cytoplasmic granules fine
-Nucleus multilobed
-found in CT
-# increase upond inflammation
Eosinophil
Granulocytes
-Cytoplasmic granules large and red-orange
-Nucleus bilobed
-Attracted by histamine
Basophil
Granulocytes
-Cytoplasmic granules large and basophilic
-Nucleus often obscurred in LM by granules
Mast cells
-found in CT
-Do not develop into mature form until at tissue destination
-Found in skin, lung, gastrointestinal tract, uterus, and serosal lining.
-Release histamine
Basophilic erythroblast
-Chromatin started to condense
-Has lots of free ribosomes and so basophilic
Polychromatophilic erythroblast
-Checkerboard appearance
-Cell is making hemoglobin so therefore color grey or bands of basophilia (ribosomes) and eosinophilia (hemoglobin)
Orthochromatophilic Erythroblast (normoblast)
-Chromatin condensed
-Cytoplasm eosinophilic bc of Hb
-Nuclus will move to periphery of cell
Reticulocyte
-Cell leaves bone marrow as this cell
Changes during granulopoiesis
1. Nucleus shape from round to bilobed to multilobed
2. Appearance of primary (magenta) granules
3. Appearance of specific granules
Promyelocyte
-only cell to produce azurophilic granules Magenta (azurophilic) granuels
-bluish-gray cytoplasm
-Clear region near nucleus is Golgi
Neutrophilic/eosinophilic myelocyte
-No magenta granules
-first exhibit specific granules
Neutrophilic/eosinophilic metamyelocyte
-indented nucleus
-numerous specific granules
-no magenta granules
Band neutrophil/eosinophile
-Stab cell
-Horseshoe shape nucleus
Myeloblasts
-first recognizable cell that begins granulopoiesis
