WBC Flashcards
Predominant WBC in adults
Neutrophils
Predominant WBC in children <4 yrs old
Lymphocyte
On determining WBC maturity, MOST valuable and reliable criterion is
Nuclear chromatin pattern
Examples of granulocytes and polymorphonuclears
Basophil
Eosinophil
Neutrophil
Examples of agranulocyte and mononuclears
Lymphocytes
Monocytes
Examples of phagocytes
Basophilic
Eosinophil
Neutrophil
Monocytes
Example of immunocyte
Lymphocyte
As granulocytes mature, the overall size decreases (true or false )
True
Most recognizable granulocytic precursor using light microscope
Myeloblast
Type of myeloblast that shows the presence of dispersed primary granules in the cytoplasm
Type II myeloblast
The synthesis of primary granules begins in the
Type II myeloblast or PROMYELOCYTE (BEST))
Last stage capable of mitosis ; synthesis of secondary granules begins
Myelocyte
Patches of grainy pale pink cytoplasm representing secondary start to become obvious in the area of the Golgi apparatus
Dawn of neutrophilia
Synthesis of tertiary granules begins ; JUVENILE CELL ; first stage of nuclear indention ; PEANUT/KIDNEY bean shaped
Metamyelocyte
STAB CELL/STAFF CELL ; YOUNGEST GRANULOCYTIC PRECURSOS to normally appear ; SAUSAGE NUCLEUS - 1/2 of the nuclear width
BAND
Drugs associated with Extreme neutropenia
Amidopyrine and Cephalosphorin (<0.5x109/L)
Predominant type of lymphocyte (normal adult blood) ; composed of mostly nucleus , scanty cytoplasm
Small lymphocyte
Size of small lymphocyte
7-10 um
Size of medium lymphocyte
10-12 um
Size of large lymphocyte
11-25 um
Final maturation of stage of b-lymphocyte
Plasma cell
Nucleus is “TORTOISE SHELL” CARTWHEEL” or “CLOCK FACE” appearance
PLASMA CELL
Cytoplasm is dark blue, SEA BLUE, CORNFLOWER in color
Plasma cell
Cytoplasm of plasma cell may contain round, discrete globules called _______ that contain immunoglobulins
