Question

multiple choice question
which leukocyte is indicated by the letter a in this image?
neutrophil
monocyte
eosinophil
basophil

Explanation:

To determine the leukocyte labeled A, we analyze the cell's morphology. Neutrophils typically have multi - lobed (usually 2 - 5 lobes) nuclei with a "segmented" appearance and fine, pale - staining granules. The cell labeled A shows a multi - lobed nucleus, which is characteristic of a neutrophil. Monocytes have a large, kidney - shaped or horseshoe - shaped nucleus. Eosinophils have bilobed nuclei and large, bright red granules. Basophils have a bilobed or S - shaped nucleus and large, dark blue granules. So, based on the nuclear morphology, the cell labeled A is a neutrophil.

Answer:

A. Neutrophil
