Q

Red blood cells

A

Small, anucleate cells
acidophilic -stain orange to red

Their diameter varies with species: goats -4.1 microns (the smallest), dogs - 7.0 microns (the largest).

Their biconcave shape causes a central pallor.

Q

Lymphocytes

A

spherical cells that are usually smaller than neutrophils.

nucleus is round with coarse, clumped chromatin.

There is a thin rim of blue cytoplasm; however, the larger lymphocytes may have proportionately more cytoplasm.

Q

monocytes

A

These cells are slightly larger than neutrophils and lymphocytes.

The nucleus is kidney-shaped, stains lighter.

Cytoplasmic vacuoles are often present and vary in size giving a foamy appearance to the blue-gray cytoplasm.

Q

Thrombocyte

A

(Spindle Cell, Thigmocyte)

(similar to platelets but not identical functions)

dark, condensed nucleus with pale basophilic cytoplasm.

1-4 dark magenta specific granules, contain 5-Hydroxytryptamine (5-HT, or serotonin)

Q

Thrombocytes granules contain:

Heterophils

A

neutrophils on non mammals
