Hemopoeisis Block 1 Flashcards
hemopoietic marrow is blank marrow
red
inactive marrow is blank marrow
yellow
red marrow is in the blank skeleton
axial
red marrow is blank percent hemopoietic cells and blank percent fat cells
50/50
fewer fat cells means blank hemopoiesis
more
white spaces in bone section
fat cells
network of reticular cells and fibers in hemopoietic bone marrow
stroma
stroma fibers provide blank network for developing cells
adhesive
reticular cells can transform into blank cells
fat
hemopoietic bone marrow features
stroma, sinuses
hemopoiesis starts in the blank about blank weeks after conception
yolk sac, 2
hemopoiesis begins in the blank about 6 weeks in utero
liver
during the hepatic period, blank hemoglobin is synthesized
fetal
blank also is a hemopoietic site from the 3rd to 5th month
spleen
period when bone marrow starts to do hemopoiesis
myeloid
bone marrow hemopoiesis starts at the blank month, becomes the major site at blank months, and continues for the rest of life
3rd, 6th
fetal blank is produced till birth
hemoglobin
hemoglobin switches from blank to blank at birth
HbF, HbA
most common sites for extramedullar hemopoiesis
spleen most common then liver
cells are in various stages of development and undergo blank so youngest cells are least numerous while older are most numerous
mitosis
most numerous blood cell type
neutrophils,
least numerous blood cell type
monocyte
second most numerous hemopoietic cell type
normoblast
megakaryoblast and descendants undergo repeated blank
endomitosis
after huge nucleus is formed in megakaryocyte, blank granulation is produced
azure
1 megakaryocyte divides into blank platelets
1000
hemopoietic nodule that forms any blood cell
colony forming unit
pluripotential hemopoietic stem cells exists and has blank marker
cd34
in marrow, there is blank pluripotential hemopoietic stem cells per 1000
1
blank does not allow the viewing of pluripotent stem cell
routine staining
in blood there is 1 stem cell per blank leukocytes
10,000
a stem cell has a choice to form this or this
myeloid (CFU, RBC, granulocyte, monocytes, etc), lymphoid (lymphocytes, plasma cells)
regulatory factors of hemopoiesis is the blank
hemopoietins
hemopoietins are blank
cytokines
erythropoietin is synthesized by cortical interstitial cells of the blank
kidney
medications such as blank are used to stimulate stem cells to produce granulocytes, and monocytes
colony stimulating factor
CFU-GM gives rise to these two
monocyte, neutrophil
most common source for hemopoietic stem cells for allogenic transplanation
peripheral blood, umbilical cord
