RBC Morphology And Identification - Quiz

This quiz is about RBC Morphology and Identification.

Questions and Answers

1.

At stage of development does the cell production begin?
- A.
  
  Adolescent
- B.
  
  Embryonic
- C.
  
  Fetal
- D.
  
  Adult
Correct Answer
B. Embryonic

Explanation
During embryonic development, the production of cells begins. This stage occurs after fertilization when the zygote starts to divide and differentiate into different cell types. The embryonic stage is characterized by rapid cell division and the formation of the basic body structures and organs. It is during this stage that the foundation for the development of all bodily systems is laid. Therefore, the correct answer is embryonic.

________________________ are produced primarily in the bone marrow and its primary function is to carry oxygen to the cells and tissues of the body.

Correct Answer
Erythrocytes, Red Blood Cells
RBCs

Explanation
Erythrocytes, also known as red blood cells or RBCs, are produced primarily in the bone marrow. Their primary function is to carry oxygen to the cells and tissues of the body.

This cell is found in the bone marrow and is the first stage in the erythrocytic series.
- A.
  
  Basophilic Normoblast
- B.
  
  Pronormoblast
- C.
  
  Polychromatic Normoblast
- D.
  
  Orthochromatic Normoblast
Correct Answer
B. Pronormoblast

Explanation
The correct answer is Pronormoblast. Pronormoblast is the first stage in the erythrocytic series and is found in the bone marrow. It is characterized by a large nucleus with fine chromatin and one or two nucleoli. The cytoplasm is basophilic and contains a few scattered ribosomes. As the erythrocytic series progresses, the pronormoblast will mature into the other stages such as basophilic normoblast, polychromatic normoblast, and orthochromatic normoblast.

Reticulocytes are best identified using what type of stain?
- A.
  
  Wright
- B.
  
  Giemsa
- C.
  
  Supravital
Correct Answer
C. Supravital

Explanation
Supravital staining is the best method for identifying reticulocytes. This staining technique allows the visualization of reticulocytes, which are immature red blood cells, by staining the residual RNA within their cytoplasm. Supravital stains are specifically designed to be used on living cells, allowing for the examination of cells in their native state without the need for fixation or cell death. Wright and Giemsa stains, on the other hand, are commonly used for staining blood smears to identify various types of blood cells, but they are not as effective in highlighting reticulocytes.

What is the term used to describe a cell of normal color?
- A.
  
  Normochromic
- B.
  
  Hypochromic
- C.
  
  Polychromic
Correct Answer
A. Normochromic

Explanation
Normochromic is the term used to describe a cell of normal color. This means that the cell has a normal amount of hemoglobin, which gives it a normal color. Hypochromic cells have a decreased amount of hemoglobin and appear pale, while polychromic cells have varying shades of color due to abnormal hemoglobin levels. Therefore, normochromic is the correct term to describe a cell of normal color.
