lecture 7B granloiesis Flashcards
at what stage do primary granules stop being formed?
beyond promyelocyte stage
which cell is the largest and in which cell feeya a rudimnetary nucleolus that can only be seen under an electron microscope
myelocyte
at which stage does the cytoplasm lose all its basophilia (it’s not bluish anymore)
myelocyte
at which stage fee appearnce of secondary or specific granules that could be neurtophilc E or B in nature hasab l Cell
myelocyte
which sateg is the stahe of diffrentation of the cell into basophile, eosinophile or neutrophile?
myelocyte
at what stage is the nucelus crescent shaped and to one side of the cell?
metamyelocye
what is the sequence?
myelobaslte-type 1-type 2-promyelocyte-myelocyte-metamyelocyte-unsegmented(band)-neutrophile
starting nymber of nucloeli in immature (type 1) myeloblast
2-5
no nuceloli are seen in the
unsegmneted (band) cell
the cytoplasm of the — cell contains very few mitcohondria nad very few ribosomes
band/ unsegmneted
unlike the band form, the neutrophile is
segmented since the band underwent segementation
So the most mature
neutrophil can have a maximum of – segments (lobes are connected by a
——— that does not contain chromatin)
five/threadlike filament
ow many nucleoli are in the promyelocyte?
1-2
appearance of secondary ranules is in—
the myelocyte
beyond te stae of —–there is only maturation.
myelocyte
wne is the nucelus at the periphery and band shaped?
unsemented neutropile (band)
wen is te cyoplasm completely loaded wit specific granules and contains very little primary granules?
unsemented (band)
explain ow the nucelus constricts to become segmented
the nucleus constricts and divides the band into two segments to start
with, then as the cell matures more, we will have three segments then 4
segments, and finally a maximum of five segments.
