* '''eosinophil''' (eosinophil granulocyte) blood cell nucleus has two lobes and cytoplasm filled with granules that stain red or pink when eosin. Cells involved with phagocytosis of antibody-antigen complexes, granules also contain histaminase and arylsufatase to degrade histamine and leukotrienes. | |||
*'''extraembryonic mesoderm''' - mesoderm lying outside the trilaminar embryonic disc covering the yolk sac, lining the chorionic sac and forming the connecting stalk. Contributes to placental villi development. | *'''extraembryonic mesoderm''' - mesoderm lying outside the trilaminar embryonic disc covering the yolk sac, lining the chorionic sac and forming the connecting stalk.

* '''neutrophil''' (neutrophil granulocytes) - most common granulocyte blood cell nucleus divided into 3-5 lobes connected by thin strands of chromatin. Cytoplasm contains two types of granules: primary granules (A granules, lysosomal enzymes) and Secondary granules (B granules, bactericidal enzymes). | |||
