Question

1. Match the following formed element of the blood with its distinguishing morphological characteristic. Basophil Eosinophil Erythrocyte Lymphocyte Monocyte Neutrophil A. Anucleate B. Kidney shaped nucleus C. Large nuclear to cytoplasmic ratio D. Orange cytoplasmic granules E. Purple cytoplasmic granules F. Segmented nucleus with 3-5 lobes

Answer 1

1.Basophils - E. Purple cytoplasmic granules

They are type of WBC

It has bilobed nucleus and purple colour granules within the cytoplasm.

2.Eosinophils - D. Orange cytoplasmic granules .

Mostly seen during allergiec condition

It has biloded nuclei, but occasionally may be trilobed .

Cytoplasm is basophilic and contains reddish orange cytoplasmic granules.

3.Erythrocytes - A. Anucleated

Also known as RBC

Appear as a biconcave disc of uniform shape and size

Anucleated( absence of nuclei )

4.lymphocyte- C. Larger. N:C ratio

N:C ratio means size of a nucleus to size of a cytoplasm .

As the cell mature it's nucleus size reduces but in lymphocytes it decreases upto 3:1 or mostly retain the original size I e 4:1.

5.Monocyte - B.Kidney shaped nucleus

Spherical in shape

Larger in size and have been shaped nucleus.

6.neutrophil - F. Segmented nucleus with 3-5 lobes

It is WBC which is mostly seen , accounts about 70 percent of total WBC count.

Spherical in shape and multinucleated.
