    • Greater palatine nerve

    • Lesser palatine nerve

    • Superior alveolar nerve

    • Inferior alveolar nerve

    • Nasopalatine nerve

    As your friend is traveling the plains of northern Wyoming in early June, he encounters an old injun who prides himself in collecting teeth from the white men. However, due to his belief in the Moon Man taking vengeance on those who cause pain he injects his homeprep of nerve block to remove the upper premolars bilaterally. In what nerve(s) would he like to inject the nerve block to inhibit pain sensation from the periodontal ligament, teeth or alveolar process?

    • Buccal branch of Lingual

    • Infraorbital nerve just above the canine fossa

    • Greater Palatine Nerve before it leaves the Greater palatine foramen

    • Just as the nasopalatine leaves the incisor foramen

    • Maxillary Nerve after the Pterygopalatine ganglion

    Correct Answer
    A. Maxillary Nerve after the Pterygopalatine ganglion
    Explanation
    The superior dental plexus (for the premolars mostly the middle superior alveolar nerves) begins to receive its contributions after V2 passes the pterygopalatine ganglion. The buccal branch supplies the buccal gingiva. The infraorbital might supply a little of the gingiva in the maxillary teeth. Greater palatine nerve does sensation to hard palate

    While on a bus traveling north from Leticia in the Colombian Amazon you encounter a woman who asks you for your saliva. At first this seems a little strange but later you learn that she wants to use it to produce her home-made chicha beverage that requires salivary amylase to allow the bacteria to ferment the sugars in the maize and mandioca. You agree and she begins massaging on the sides of your jaw in order to increase blood flow to your sublingual and submandibular glands. To increase blood flow to both of these glands she wants to stimulate blood flow from which artery?

    • Inferior alveolar artery

    • Facial Artery

    • Lingual artery

    • Sphenopalatine Artery

    Correct Answer
    A. Facial Artery
    Explanation
    Facial artery - facial artery gives off the submental artery that according to Dr. Dhiman's oral cavity lecture supplies both sublingual and submandibular glands. Lingual artery supplies bloodflow to the sublingual gland but not to the submandibular.

    What nerve fibers synapse in the pterygopalatine ganglion?

    • GVA Sympathetic fibers of the Nerve to the Pterygoid canal

    • GVE Sympathetic fibers the Greater Petrosal nerve

    • GVE Parasympathetic fibers of the Oculomotor Nerve

    • GVE Parasympathetic fibers of the Nerve of the Pterygoid canal

    • GVA Parasympathetic fibers of the Nerve of the Pterygoid canal

    Correct Answer
    A. GVE Parasympathetic fibers of the Nerve of the Pterygoid canal
    Explanation
    Greater Petrosal Nerve (VII) joins with Deep Petrosal Nerve (SNS) to form Nerve of the Pterygoid Canal which carries GVE (PSNS and SNS), GVA, and SVA (from palate). Only PSNS GVE synapse in PPG.

    • Facial

    • B&C

    • All of the Above

    Correct Answer

    Matt Hasselback retaliates on Ned by punching him in the right eye. Ned suffers a blowout fracture resulting in herniation of orbital soft tissues into one of his paranasal sinuses. On the below MRI, which arrow indicates the most likely area of herniation? - ProProfs

    Matt Hasselback retaliates on Ned by punching him in the right eye. Ned suffers a blowout fracture resulting in herniation of orbital soft tissues into one of his paranasal sinuses. On the below MRI, which arrow indicates the most likely area of herniation?

    • A

    • B

    • C

    • D

    Correct Answer
    A. C
    Explanation
    blow-out fracture refers to fracturing the orbital floor, so soft tissue may herniate into the maxillary sinus.

    Due to his love for the Backstreet Boys, Paul hyperventilates every time a song comes on. After spending months listening to them, what clinical syndrome is he likely to have?

    • Metabolic alkalosis

    • Atelectasis

    • Thoracic outlet syndrome

    • Horner’s

    • Metabolic acidosis

    Correct Answer
    A. Thoracic outlet syndrome
    Explanation
    habitual hyperventilation can lead to hypertrophy of the accessory muscles of respiration including the anterior and middle scalenes which can compress the brachial plexus and/or subclavian artery. Hyperventilation does cause respiratory alkalosis which will be compensated by healthy kidneys (but not to the point of acidosis).

    A 15 year old boy falls from his bicycle and hits his head. His initial examination in the ER is normal, but later in the day, he becomes noticeably lethargic. He is brought back to the ER where he is too drowsy to answer the examiner's questions. His right pupil is 7mm and his left is 4mm. Patellar tendon reflexes are brisker on the left, and a Babinski sign can be elicited on the left. CT imaging reveals that a pool of blood has displaced the right temporal lobe to the left. The hematoma is evacuated, and a blood vessel is cauterized. Through which opening did the lacerated blood vessel enter the cranial cavity?

    • Foramen Spinosum

    • Stylomastoid Foramen

    • Foramen lacerum

    • Carotid Canal

    • Jugular Foramen

    Correct Answer
    A. Foramen Spinosum
    Explanation
    Middle Meningeal Artery rupture causes epidural hematoma.

    • Medial nasal prominences from each side

    • Frontonasal prominence with each maxillary prominence

    Davis, an AMSA member and second semester medical student, shadows a tonsillectomy. During the procedure, the surgeon asks the group of Ross AMSA members to name the two arches that border the Palatine Tonsils. Davis enthusiastically replies with the correct answer:

    • Anterior Tonsillar Arch & Posterior Tonsillar Arch

    • Palatoglossal Arch (Anteriorly) & Palatopharyngeal Arch (Posteriorly)

    • Palatopharyngeal Arch (Anteriorly) & Palatoglossal Arch (Posteriorly)

    • Torus Tubarius (Anteriorly) & Salpingopharyngeal fold (Posteriorly)

    • Palatoglossal folds (Anteriorly) & Salpingopharyngeal fold (Posteriorly)

    Correct Answer
    A. Palatoglossal Arch (Anteriorly) & Palatopharyngeal Arch (Posteriorly)
    Explanation
    The Palatoglossal Arch is anterior to the palatine tonsil and the Palatopharyngeal Arch is posterior to the palatine tonsil. Answer choice A simply doesn't exist. Answer C has incorrect spacial relationships. Answer D contains structures that are found further posterior and superior in the naso/oropharynx (See Nasal Cavity Lecture). Answer E is only half correct.

    A patient has been complaining of tooth pain in his upper jaw for the past 2 weeks. Upon doing a full interview, you learn that your patient was born with a congenital condition known as situs inversus. He also has karatgener's syndrome and is infertile. He says his whole head feels heavy, his face hurts, and he has been somewhat congested as well. As a recent Ross graduate, you know that the upper row of teeth is innervated by the superior alveolar nerve, a branch of the maxillary nerve, but you recall your Anatomy Professors warning you differentiate face and tooth pain from something else. Given the history of the patient, what is he most likely suffering from?

    • Damage to Internal Nasal Nerve

    • Damage to Lesser Palatine nerve

    • Infection of Sphenoidal sinus

    • Infection of the Maxillary sinus

    • Damage to the Greater Palatine Nerve

    Correct Answer
    A. Infection of the Maxillary sinus
    Explanation
    The history of this patient suggests that he has immotile ciliary syndrome (given his situs inversus, kartagener's and infertility). Drainage of the paranasal sinuses is also dependent on the function of cilia. Hence people with impaired ciliary function, including smokers, are more susceptible to sinusitis due to impaired drainage of the sinuses. In this case, the maxillary sinus is infected. It's proximity to the upper row of teeth (superior alveolar nerve), and the orbit (inferior orbital nerve) is noteworthy. Infection of the maxillary sinus often presents with face and tooth face.
