Normal blood cell identification Flashcards
Canine blood, what are the cells
Segmented neutrophils.
Note irregular shape and irregular, non-parallel sides to the nucleus. Neutrophils may have very faint ‘neutral’ staining granules that vary in prominence.
Canine blood, identify the cells
Monocytes.
Monocytes create confusion because of highly irregular nuclear shape, often being confused with neutrophils. Monocytes will have larger diameter than adjacent neutrophils and monocyte cytoplasm is darker blue-gray. The cytoplasm may have vacuoles
canine blood, identify the cell
Lymphocytes.
Small resting lymphocytes in the circulation usually have a round nucleus, with little to no cytoplasm – similar to the cell on the left. Variants may have increased cytoplasm – similar to the cell on the right. Nuclear shape can have an indentation, but in all cases small lymphocytes will have chromatin condensed into the clumpy pattern shown
feline blood identify the cells
Long arrow. Feline basophil. The cytoplasm is typically consists of a pavement stone arrangement of faintly staining granules.
Short arrow. Platelet. Several are in the field of view.
canine blood, identify the cell
Long arrow.
Eosinophil, note large eosinophilic granules
Short arrow.
Platelet
Arrowhead.
Segmented neutrophil, note very faint neutrophilic granules
canine blood, identify the cells
Long arrow.
Eosinophil, note large eosinophilic granules. There are a few cytoplasmic vacuoles; these are washed out granules.
Short arrow.
Segmented neutrophil.
feline blood, identify the cells
Long arrow.
Feline eosinophil. The cytoplasm packed with short rod shaped granules.
Short arrow.
Segmented neutrophil.
Arrowhead
Lymphocyte.
canine blood- identify the cells
Arrows
Nucleated red blood cells (NRBC)
Note nuclear condensation leading to pyknosis.
Associated polychromatophilic erythrocytes are indicated by arrowheads.
what are these retile cells?
Erythrocytes (bigger) and thrombocytes is (platlet) (smaller)
what are these reptile cells?
erythrocytes, heterophils (red), eosinophil (bottom of image), have blue granules in reptile
what is this reptile cell?
azurophil
what is this reptile cell?
monocyte
what are these rabbit cells?
(A) RBCs and platelets.
(B) Heterophil
(C) Lymphocyte
(D) Eosinophil
(E) Basophil
(F) Monocyte
what is this avian cell?
Erythrocyte
these are rabbit RBCs, describe them, this is a normal finding, why?
- Anisocytosis and polychromasia is a common, normal finding
- May be due to shorter erythrocyte life span (57-67 days)
what is this avian cell?
thrombocyte
what is this avian cell?
Heterophil
avian blood - what are the two different cells here?
Square - heterophil
circle - eosinophil
what is this avian cell?
Basophil
what is the avian cell indicated by an arrow here?
lymphocyte
what is this avian cell?
monocyte
