    5. comes back along lateral aspect of trachea
  14. 14Damage to the recurrent laryngeal nerve can cause...Decreased innervation to the cricoarytenoideus dorsalis resulting in lack of abduction of the arytenoid cartilages during inhalation
  15. 15Describe laryngeal hemiplagia and symptomshemiplagia- only one side damaged

  21. 21Point to the 3rd quadrant of your mouth based on the triadan systemShould be pointing to your bottom Left
  22. 22Which are the only teeth in the K9 to have 3 roots?Upper P4, M1, M2 have how many roots?
  23. 23Which arteries should you watch out for especially during dentals and tooth extractions on the upper arcade?Palatine a. and even infraorbital
  24. 24The lingual artery runs with which cranial nerve?Cranial nerve XII runs with which major artery?
  25. 25Describe a retrobulbar abscesswhen the animal opens its mouth it experiences pain due to the temporalis pushing against the periorbita
  26. 26Where should the periorbita drain?Caudal to the last molar is where this drains into
  27. 27The vertical ear canal is associated with which cartilage(s)?Auricular cartilage
  28. 28The horizontal ear canal is associated with which cartilage(s)?Auricular and Annular Cartilages
  29. 29This is located at the junction of the auricular cartilage and the external acoustic meatusThe tympanic membrane is located at the junction of (blank) and (blank)
  30. 30Where are the molar salivary glands located?In cats only, these glands are located on the lingual surface of 308 and 408
  31. 31Describe a sialocele and which gland is most often affectedThe parotid gland is most likely to be damaged or blocked causing this problem
  32. 32Define MiosisConstriction of the pupil
  33. 33Define mydriasisDilation of the pupil
  34. 34CN III has which neural properties associated with it?Parasympathetic properties because it leads to pupil constriction (miosis)
  35. 35Which ligaments must be cut during an enucleation?Medial and lateral palpebral ligaments (FYI, Medial is more developed and tougher)
  36. 36How many total teeth do dogs and cats have?Dogs 42

  37. 37Which meatus is preferred for GI tubing in the equine?Ventral
  38. 38What is the fundus?The back portion of the eye that can be examined
  39. 39What is the philtrum?the 'line' that divides lip and nose
  40. 40Which bone(s) make(s) up the hard palate?Incisive, Maxilla, and Palatine
  41. 41Between conical, vallate, fungiform, and filiform papillae, which one(s) is/are responsible for taste?Vallate, fungiform, and filiform papillae are all associated with taste
  42. 42Which muscle retracts and elevates the tongue?Styloglossus m has this action on the tongue
  43. 43Which muscle retracts and depresses the tongue?The hyoglossus m has this action on the tongue
  44. 44Which muscle protrudes the tongue?The genioglossus m has this action on the tongue
  45. 45What structure(s) notes the beginning of the opening of the oropharynx?The palatoglossal arches
  46. 46Where does the oropharynx start and end?starts at the palatoglossal arch and continues until the base of the epiglottis
  47. 47The palatopharyngeal arches connects which 2 structures?This structure connects the soft palate to the nasopharynx
  48. 48What are the choanae in relation to the pharynx?These are the openings of the left and right nasal cavities into the nasopharynx
  49. 49What are the 'borders' of the laryngopharynx?it is dorsal to the larynx and starts from the palatopharyngeal arches and extends to the beginning of the esophagus
  50. 50What are the muscles associated with the pharynx?From rostral to caudal:
    Hyopharyngeus
    Thyropharyngeus
    Cricopharyngeus
  51. 51In order from rostral to caudal, what are the 4 cartilaginous structures of the larynx?Epiglottis
    thyroid
    arytenoid
    cricoid
  52. 52What are the actions of the thyroarytenoidus m?relaxes vocal folds and constricts glottis
  53. 53What's the difference between the glottis and the rima glottis?The glottis is like the door frame (vocal folds, processes of arytenoid cartilages) and the rima glottis is the actual space or 'doorway'
  54. 54What is the significance of the hyoid apparatus?It supports the larynx and the tongue
  55. 55What is significant about the ethmoidal labyrinth?This is where smell is detected and the signal is sent to the brain

  60. 60This lymph node drains pretty much the rest of the head below eye levelMandibular lymph node
  61. 61This lymph node drains mostly the side of the facemedial and lateral retropharyngeal lymph nodes
