Vaginal Cytology

Question 1

Cells are almost exclusively clusters of round, well-formed nucleated epithelial cells. The nucleus will stain darker than the cytoplasm

Answer 1

Proestrus

Question 2

Cells are predominantly cornified squamous epithelial cells, present in densely packed clusters.

Answer 2

Estrus

Question 3

These cells lack a nucleus and have an angular appearance.

Answer 3

Estrus

Question 4

Small darkly stained leukocytes predominate

Answer 4

Metestrus

Question 5

. Cornified squamous epithelial cells may be observed, often in fragments.

Answer 5

Metestrus

Question 6

The leukocytes are generally neutrophils with sausage-link nuclei which stain very dark purple.

Answer 6

Metestrus

Question 7

The predominant cells are leukocytes.

Answer 7

Diestrus

Question 8

Also present will be nucleated epithelial cells and rarely cornified squamous epithelial cells.

Answer 8

Diestrus

Question 9

Where should be the sample be collected from

Answer 9

cranial vagina

Question 10

This cell look like small O shaped oat cereal pieces

Answer 10

Parabasal Cells

Question 11

this looks like a fried eggs

Answer 11

intermediate cells

Question 12

cells which looks like corn flakes; neutrophils and red blood cless

Answer 12

superficial cells

Question 13

4 phases of estrous cycle

Answer 13

anestrus (not in heat)
proestrus (early estrogen influence)
estrus (receptive, fertile)
diestrus (luteal phase)

Question 14

parabasal cells predominate on this phase

Answer 14

anestrus

Question 15

a gradual shift from parabasal and intermediate cells and finally superficial cells occur

Answer 15

proestrus

Question 16

superficial cells predominate and their nuclei become pyknotic or absent/anuclear

Answer 16

estrus

Question 17

marked by precipitous decline in the number of superficial cells and reappearance of intermediate and parabasal cells within 1 to 2 days

Answer 17

diestrus

Question 18

neutrophils are commonly observed on this phase and large numbers of bacteria are also often present

Answer 18

diestrus ?(luteal phase)

Question 19

composed of parabasal cells small and large intermediate cells; a few superficial cells

Answer 19

early proestrus

Question 20

predominantly superficial cells and medium to large intermediate cells. The edges are straight and the cells are flattened

Answer 20

Late Proestrus

Question 21

The cells are cornified

Answer 21

Estrus

Question 22

onset of this phase is characterized by the sudden appearance of parabasal cells; a change from predominantly noncornified

Answer 22

diestrus

Question 23

what are the 4 different types of cells

Answer 23

parabasal cells
small intermediate cells
large intermediate cells
superficial cells
metestrus cells

Question 24

this type of cell slightly larger than parabasal cells, borders irregular

Answer 24

small intermediate cells

Question 25

large cells with irregular borders

Answer 25

large intermediate cells

Question 26

largest cells seen; borders irregular, no nucleus present

Answer 26

superficial cells

Question 27

small, round, slightly oval, large vesiculated nucleus and small cytoplasm.

Answer 27

Parabasal cells

Question 28

parabasal cells with infiltration of a varying number of nucleated cells

Answer 28

metestrus cells

Question 29

slightly larger than parabasal cells to twice that size

Answer 29

Intermediate cells

Question 30

Smooth, oval to rounded irregular borders, nucleus smaller than in parabasal cells. More cytoplasm than parabasal cells.

Answer 30

Intermediate cells

Question 31

Are dead cells, are the largest in vaginal cytology with a sharp, flat, angular cytoplasmic borders and a small pyknotic, fading nuclei or without nuclei.

Answer 31

Superficial cells

Question 32

irregular vaginal cells, no nucleus, smaller than superficial. These are the cells that have also been called "fully cornified."

Answer 32

Anuclear squames

Question 33

Large intermediate vaginal cells that appear to have one or more neutrophils in their cytoplasm. Are typical of bitch diestrus.

Answer 33

Metestrus cells

Question 34

parabasal and intermediate cells with obvious cytoplasmic vacuoles. May be associated with diestrus and anestrus.

Answer 34

Foam cells

Question 35

Inflammatory cells that can be normal or abnormal in vaginal cytology in function of the estrus period

Answer 35

Neutrophils

Question 36

Blood can be normal in the bitch but always is abnormal in the queen

Answer 36
