| Three proliferating cells capable of mitosis are ... | myeloblasts, promyelocytes, myelocytes |
| What kind of WBC is smaller than a promyelocyte, has motility, a round to oval nucleus with a flattened side near the golgi apparatus, and azurophilic granules? | myelocyte |
| What kind of WBC has a nucleus that's less than 50% indented, clumped chromatin, both secondary and primary granules? | metamyelocyte |
| What kind of WBC has a nucleus that's indented by more than 50%, full motility, adhesion properties, and all secondary granules in the cytoplasm? | band |
| What kind of WBC has a multilobed nucleus held together by strands, a mult-segmented nucleus, and a clumped, lobulated nucleus? | seg |
| Dohle bodies, vacuoles, and toxic granulation means the WBC is __. | digesting something |
| What are two examples of a markers that denote a cell that is an opsonin? | immunoglobulins and complements |
| What kind of cell has red-eosin secondary granules, can be find in greater numbers during an allergic reaction, and fights parasites? | eosinophil |
| What kind of cell is deep purple to black in color, has irregularly shaped granules, has 2 lobes, has granules with both heparin and histamine in them, and a high affinity for IgE (allergy antibodies)? | basophil |
| What kind of WBC is usually seen in tissue and rarely seen in the blood stream? | basophil |

| What kind of agranular WBC has an eccentric nucleus, 1 to 2 nucleoli, and is usually seen in the bone marrow and spleen? | monoblast |
| What kind of agranular WBC is the same size as monoblast, has some granulation, has a moncytoid appearance, and is motile for phagocytosis? | promonocyte |
| What kind of WBC has a varying granular content, great morphological variety, an indented nucleus, and is very motile? | monocyte |
