    Temporalis
  17. A 38-year-old female patient complained of parotid pain that increased while eating. Intraoral examination detected some pus oozing from the parotid duct opening. What was the most likely anatomical reference that the physician considered to locate the parotid duct opening?
    Mucosa of the sublingual caruncle behind the central incisor teeth
    Mucosa of the cheek across the 2nd upper (maxillary) molar tooth
    Mucosa of the floor of the mouth along the sublingual fold
    Mucosa of the cheek across the 2nd lower (mandibular) molar tooth
  18. While recovering from a right facial paralysis, a 36-year-old female patient complained that food accumulated between the teeth and the cheek mucosa when chewing. The deficiency of which muscle was most likely the cause of the chewing problem?
    Zygomaticus major
    Orbicularis oris

    Vagus
  21. Frey's Syndrome is marked by profuse sweating over one cheek, temple, and surrounding areas of the face, precipitated by eating.
