2.2 Flashcards
FACTORS AFFECTING RBC PRODUCTION
1. inhibit EPO production
2. enhances EPO production
3. 2 vitamins that are important in synthesis of DNA
- disease affected by delayed nuclear maturation
4. important in Hgb synthesis (2)
5. protein needed in hgb production
- Estrogen
- Testosterone
- Folic acid, Vitamin B12
- megaloblastic anemia - Iron, Copper
- Globin in Hgb
- ______ produces neutrophils
- ___ > ____ > neutrophils - ______ produces eosinophils
- ______ produces basophils
- how many days from blast stage to release
- CFU-G
- CFU-GM > CFU-G > Neutrophil - CFU-Eo
- CFU-Baso
- 14 days
STAGES OF GRANULOPOIESIS
- more immature = larger nucleus; no granules
- primary granules stars to appear
- primary granules aka
- Myeloblast
- Promyelocyte
- Azurophilic gramules
STAGES OF GRANULOPOIESIS
- number of Azurophilic granules starts to decrease
- ____/_____ starts to appear
- late in this stage, ______ starts to appear
- secondary granules appear reddish tinge resulting now as if sun is coming out _______
- unstained portion in this ^ - nucleus starts to undergo identation
- aka
- further production of ____
- how do you call these granules
- basophil color
- neutrophil color
- eosinophil color
- Myelocyte
- Secondary granules or Specific granules
- Tertiary granules
- Dawn of Neutrophilia
- golgi complex - Metamyelocyte
- Juvenile cell
- tertiary granules
- gelatinase granules
- dark blue to black
- pink to lilac
- orange red
STAGES OF GRANULOPOIESIS
- youngest stage to appear in circulation
- nucleus undergoes ______
- often __-shaped (3)
- stage that normally appear in the circulation with the amount of at least ___ to __%
- more than this %, indicates ______ - Mature Neutrophil aka ______
- Band/ Stab Cell/ Staff Cell
- elongation
- C,U,S- shaped
- 0-5%
- acute leukemia - Polymorphonuclear Neutrophil (PMN)
How to differentiate:
- myeloblast vs promyelocyte
- promyelocyte vs myelocyte
- myelocyte vs metamyelocyte
- metamyelocyte vs band cell
- cytoplasmic granulation
- appearance of granules
- shape of nucleus
- nuclear morphology
- stages that are mitotically active
- first stage incapable of mitosis
- myeloblast > promyelocyte > myelocyte
- metamyelocyte
