Flashcards in Hemopoeisis Block 1 Deck (38):
1

hemopoietic marrow is blank marrow

red

2

inactive marrow is blank marrow

yellow

3

red marrow is in the blank skeleton

axial

4

red marrow is blank percent hemopoietic cells and blank percent fat cells

50/50

5

fewer fat cells means blank hemopoiesis

more

6

white spaces in bone section

fat cells

7

network of reticular cells and fibers in hemopoietic bone marrow

stroma

8

stroma fibers provide blank network for developing cells

adhesive

9

reticular cells can transform into blank cells

fat

10

hemopoietic bone marrow features

stroma, sinuses

11

hemopoiesis starts in the blank about blank weeks after conception

yolk sac, 2

12

hemopoiesis begins in the blank about 6 weeks in utero

liver

13

during the hepatic period, blank hemoglobin is synthesized

fetal

14

blank also is a hemopoietic site from the 3rd to 5th month

spleen

15

period when bone marrow starts to do hemopoiesis

myeloid

16

bone marrow hemopoiesis starts at the blank month, becomes the major site at blank months, and continues for the rest of life

3rd, 6th

17

fetal blank is produced till birth

hemoglobin

18

hemoglobin switches from blank to blank at birth

HbF, HbA

19

most common sites for extramedullar hemopoiesis

spleen most common then liver

20

cells are in various stages of development and undergo blank so youngest cells are least numerous while older are most numerous

mitosis

21

most numerous blood cell type

neutrophils,

22

least numerous blood cell type

monocyte

23

second most numerous hemopoietic cell type

normoblast

24

megakaryoblast and descendants undergo repeated blank

endomitosis

25

after huge nucleus is formed in megakaryocyte, blank granulation is produced

azure

26

1 megakaryocyte divides into blank platelets

1000

27

hemopoietic nodule that forms any blood cell

colony forming unit

28

pluripotential hemopoietic stem cells exists and has blank marker

cd34

29

in marrow, there is blank pluripotential hemopoietic stem cells per 1000

1

30

blank does not allow the viewing of pluripotent stem cell

routine staining

31

in blood there is 1 stem cell per blank leukocytes

10,000

32

a stem cell has a choice to form this or this

myeloid (CFU, RBC, granulocyte, monocytes, etc), lymphoid (lymphocytes, plasma cells)

33

regulatory factors of hemopoiesis is the blank

hemopoietins

34

hemopoietins are blank

cytokines

35

erythropoietin is synthesized by cortical interstitial cells of the blank

kidney

36

medications such as blank are used to stimulate stem cells to produce granulocytes, and monocytes

colony stimulating factor

37

CFU-GM gives rise to these two

monocyte, neutrophil

38

most common source for hemopoietic stem cells for allogenic transplanation

peripheral blood, umbilical cord
