Question

Match the types of WBC listed under column I with the shape of nucleus given under column II and select the correct option from codes given below
Column IColumn IIA.Neutrophils(i)Kidney-shapedB.Eosinophils(ii)S-shapedC.Basophils(iii)3 to 5 lobesD.Monocyte(iv)2 lobes(v)Disc-shaped

Answer 1

Answer:

Hypersegmented neutrophil. When stained, neutrophils have a segmented nucleus and pink/orange cytoplasm under light microscope. The majority of neutrophils have three nuclear segments (lobes) connected by tapering chromatin strands. A small percentage have four lobes, and occasionally five lobes may be seen.

Eosinophils usually have bilobed nuclei.

Basophilic granulocytes have a 2 or 3 lobed nucleus. The lobes are usually not as well defined as in neutrophilic.

granulocytes and the nucleus may appear S-shaped.

Monocytes have one large nucleus, which is usually centrally placed within the cell and often kidney shaped.

So, the correct answer is 'a=(iii), b=(iv), c=(ii), d=(i)'.
