Frog anatomy

  1. Describe the eyelids
    • fixed upper lid
    • thin lower lid
    • nictitating membrane
  2. This skin gland is often poisonous
    parotid gland
  3. external eardrums are called
  4. The bones of the skull
    • frontoparietal
    • nasal
    • premaxilla
    • maxilla
    • dentary
    • exoccipital - occiptal condyle & foramen magnum
  5. The bones of the vertebral column
    • atlas
    • vertebrae 2 - 8
    • sacral vertebra
    • urostyle
  6. The vertebrae have these processes
    • dorsal spinous
    • transverse
  7. what type of teeth are the maxillary teeth
  8. these are in the mouth, paired, and help hold onto prey
    vomerine teeth
  9. the mucosal covered larynx is called
    laryngeal prominence
  10. common chamber for the digestive, urinary, and reproductive systems
  11. these provide energy for the mating season and during dormancy
    fat bodies
  12. Describe gular/buccal pumping
    air is drawn through the nares by contractions of the mouth floor & forced into the lungs by closing the nares and raising the mouth floor
  13. The three ways frogs breathe
    • cutaneous respiration
    • buccopharyngeal respiration (mucous membranes of the mouth and pharynx)
    • pulmonary respiration
  14. The shift from the tadpole to the adult is controlled by:
    • thalamus
    • hypothalamus
    • pituitary gland
    • thyroid gland & hormones
  15. Some salamanders retain gills through adulthood. What is this called?
  16. The heart contains how many chambers?
    3 - two atria and a ventricle
  17. large artery that leaves the ventricle of the heart
    bulbis cordis
  18. This carries blood into the right atrium
    sinus venosus
  19. What is the function of the spiral valve and where is it located?
    It is located in the bulbis cordis. It diverts oxygenated blood to the carotid and aortic arches and de-oxygenated blood to the pulmocutaneous arch
  20. The truncus arteriosus has ______ branches
    left and right
  21. What branches off of the truncus arteriosus?
    • carotid arch 
    • aortic arch
    • pulmocutaneous arch (deoxygenated blood to lungs and skin)
  22. The left and right aortic arches come together to form:
    dorsal aorta
  23. What are the 3 venous portal systems?
    • - hypophyseal portal system
    • - renal portal system - drains to kidney from visceral structures and muscle
    • - hepatic portal system - digestive system to liver
  24. In males: Transverse collecting tubules from the kidneys collect urine and merge with what structure
    efferent ductules from the testes
  25. This is the part of mating where the male leaps on the female's back & holds her
  26. mating is called
  27. This is the term for a female that is full of eggs
  28. What happens if a gravid female does not find a mate?
    She will not lay her eggs and they will be absorbed by her body
  29. The developing young (tadpoles) are called
  30. The change from larva to adult
  31. These are states of dormancy in the winter and summer
    brumation & estivation
  32. Name 7 veins found in the frog
    • hepatic portal vein
    • renal portal vein
    • ventral abdominal vein
    • caudal vena cava
    • Left cranial vena cava
    • right cranial vena cava
    • sinous venosus
  33. These carry both urine and sperm
  34. These extend into the kidneys and merge with transverse collecting tubules
    efferent ductules
