Hematopoiesis Flashcards
Color of bone marrow
Yellow Marrow (Adipose) Red Marrow (hematopoiesis)
Relative size of cells in smear
RBCs and lymphocytes usually smallest
Larger cells usually less developed than smaller cells
Erythroid Cells
Round central nuclei
Chunky chromatin
Plasma cells
Lots of cytoplasm
Presence of golgi
Lymphocytes
Very little cytoplasm
Mottled nuclei
Proerythroblast
Medium to large cell
Large round nucleas
Rim of blue cytoplasm
Basophilic erythroblast
Smaller
2nd type
Round central nucleas
Bright blue cytoplasm
Polychromatophilic Erythroblast
Third stage
Smaller
Greyish cytoplasm
Nucleus round central and chunky
Normoblast
Small tightly knotted nucleus
Cytoplasm like that of RBC
Mature erythroblast
Red color
Biconcave disc
No nucleus
Myeloblast
Similar to other early stage blasts
Promyelocyte
Large
Purple cytoplasmic granules
Nucleoli visable
Neutrophilic myelocyte
Specific granules visable
Oval or indented nucleus
Neutrophilic metamyelocyte
Specific granules throughout cells
Nucleus bean shaped
Band Neutrophil
Ribbon Nucleus
