Answer:

Nucleus: dense

Cytoplasm: increasingly red in color

Size: smaller than rubricyte

Question 2: define Elliptocytes

Answer:

cigar shape (narrow)

Question 3: what are the 3 basic functions of the cellular membrane?

Answer:

• selective permability

• facilitates cell to cell recognition

• supports blood grps. to aid in cellular identity

Question 4: 13. Describe a band /stab. (note any characteristics about the cell. . .)

Answer:

Its nucleus can be shaped like a horseshoe, C or S = all sides of nucleus are parallel, smaller than a metamyelocyte, pink cytoplasm. In peripheral blood its found in marginating/circulating pools

Question 5: 19. Define erythropoiesis

Answer:

Erythropoiesis is a glycoprotein that stimulates the production and differentiation of erythrocytes (RBCs).It is produced primarily in the kidneys

Question 6: 30. Where in the body can mast cells be found?

Answer:

Mast cells are considered tissue cells, in that they move into the tissues to the source of the infection, inflammation, etc. to do their job

Question 7: What is the last cell in maturation sequence capable of mitosis?

Answer:

Myelocyte

Question 8: 12. What is transferrin and what is its function?

Answer:

Transferrin, a plasma protein, carries iron in the ferric (Fe3+) form to the developing RBCs.

Question 9: 9. What is the structure of the complete hgb molecule?

Answer:

protoporphyrin ring Question 10: What are "retics" indicators of when stained with supravital stain?

Answer:

Indicators of bone marrow function, precipitated RNA can be seen

Question 11: 16 What are cytokines. What are the functions of cytokines?

Answer:

"growth factors" which aredescribe a diverse group of soluble proteins that regulate the functional activities of cells: they are responsible for simulation, inhibition or differentiation of mature blood cells

Question 12: Describe the nucleus and cytoplasm of a promyelocyte (WBC)

Answer:

Nucleus: occupies about ½ the cell (lower N:C ratio than myeloblast), round/oval/slightly indented, chromatin pattern is somewhat courser than myeloblast, nucleoli are present. Blue/med. blue primary undifferentiated granules

Question 13: 17. Describe a basophil.

Answer:

The basophil is characterized by the presence of large blue/black granules unevenly distributed in its cytoplasm.

Question 14: define anticoagulant

Answer:

Any agent used to prevent the formation of blood clots

Question 15: define Normochromic

Answer:

Hgb content (central pallor) occupies 1/3 of RBC

Question 16: define Teardrop (dacryocyte), what dieases associated with?

Answer:

teardrop or pear shape with elongated tail,thalassemias and myeloid metaplasia Question 17: 8. What are the granules called which are present in the promyelocyte stage?

Answer:

PRIMARY, undifferentiated granules are seen in the cytoplasm

Question 18: 11. What is the life span of the RBCs?

Answer:

120 days +/- 20 days

Question 19: Hemoglobin C crystals

Answer:

single dark red staining hexagonal shaped RBC inclusion,

associated with homogenous hgb C disease

Question 20: 14. Describe a mature neutrophi/PMN/segment ("seg"). (note any characteristics about the cell..)

Answer:

2-5 lobes, cytoplasm is pink in color and contains fine azurophilic granules, most abundant WBC produced.Question 21: What is the purpose of using the low power magnification (10X) when performing an examination of a blood smear?

Answer:

To bring into focus the field of view and then you can check for clarity and even distribution of cells and quality of the slide Question 22: When making a blood smear, why is it so important to maintain, even gentle pressure on the pusher slide?

Answer:

adding pressure to the pusher slide will cause distribution of the cells to be abnormal causing wrong patient results.Question 23: What two types of WBC's are found in both the bone marrow and peripheral blood?

Answer:

(Bands/Stabs) and (Neutrophil/PMN/Segs)

Question 24: 29. What are mast cells?

Answer:

Mast cells are stimulated basophils.

Question 25: 5. What is the metal that is associated with the hgb molecule?

Answer:

Iron

Question 26: what is the function of the RBC?

Answer:

RBC's serve as carriers of oxygen to all parts of the body
