Polymorphonuclear leukocytes

45
Q

The granules of this granular leukocyte are smaller than its counterparts, evenly distributed, and pale lilac. Do not strongly attract either the acidic or basic stain

A

neutrophil

46
Q

The granules of this granular leukocyte usually do not cover or obscure the nucleus, which most often has two lobes connected by either a thin strand or a thick strand of nuclear material. Large and uniform-sized granules. Stain red-orange with acidic dyes

A

Eosinophil

47
Q

Round, variable-sized granules. The granules of this granular leukocyte commonly obscure the nucleus, which has two lobes. Stain blue-purple with basic dyes

A

Basophil

48
Q

The nucleus of this agranular leukocyte stains dark and is round or slightly indented. The cytoplasm stains sky blue and forms a rim around the nucleus

A

Lymphocyte

49
Q

The nucleus of this agranular leukocyte is usually kidney-shaped or horseshoe-shaped. Stains blue-gray and has a foamy appearance
