  1. Reptile cells readily _____.
    rupture
  2. Which WBCs are rare in snakes?
    • eosinophils
    • monocytes
  3. Do we know alot about reptile hematology?
    no
  4. Where are the places we can collect blood in snakes?
    • ventral coccygeal
    • heart
    • palantine veins
  5. What is the ventral coccygeal vein?
    tail vein
  6. Do we use the palantine veins often?  Where are they?
    • no
    • roof of mouth
  7. Where is the ventral coccygeal vein?
    behind the vent
  8. What is the vent?
    scale that covers the cloaca (where poop, pee, and eggs come out)
  9. Where can we collect turtle blood?
    • jugular vein
    • occipital plexus
    • brachial vein
    • subcarapacial sinus
  10. Which place is the easiest to collect in a turtle?
    jugular
  11. Where is the occipital plexus?
    back of the head
  12. Where is the subcarapacial sinus?
    under the shell right below the carapace
  13. Which turtles do we use the subcarapacial sinus the most in?
    aquatic turtles
  14. If we aren't careful what might contaminate our subcarapacial sinus sample?
    might accidently hit the lymph sinus and our lymphocytes will be elevated...the blood will be a milky color

    20 - 40%
  19. What can cause the PCV to vary?
    • nutrition
    • sex
    • environment
  20. What do heterophils look like in reptile blood?
    numerous fusiform (rod shaped) eosinophilic granules
  21. What is the most common granulocyte?

  22. What percent of leukocytes are heterophils in reptiles?
    40%
  23. What kind of nucleus do heterophils have in reptiles?
    • single nucleus
    • round to oval
  24. What do eosinophils look like in reptiles?
    • cytoplasmic eosinophilic granules

  25. What colors are the granules stained in eosinophils in iguanas?
    stain blue
  26. What do basophils look like in reptiles?
    blue to purple granules in cytoplasm
  27. What color are the granules in basophils in iguanas?
    red
  28. What do the granules usually do to the nucleus in a basophil?
    obscure the basophil
  29. How many basophils do we normally see in reptiles?
    up to 40%
  30. What do lymphocytes look like in reptiles?

  32. What are azurophils in reptiles?
    cytoplasm has fine eosinophilic granules and appears red
  33. What are azurophils derived from?
    monocytes
  34. How do we count azurophils?
    count it as a monocyte for our calculations but count separately on the differential
  35. What do thrombocytes look like in reptiles?
