300
Underneath each Nasal Conchae is its Nasal Meatus. Name the openings in each Meatus.

C5, C6 Name Which Cords these nerves are associated with List the nerves that BOTH (and ONLY BOTH) are associated with.
Cords: Lateral (w/ C7), Posterior (w/ C7,C8,T1) Nerves: Suprascapular, Upper Subscapular n., Lower Subscapular n, Axillary n.,
300
Name the 2 Nerves That Occupy/Make Up The Pterygoid Canal. State whether they are Parasympathetic or Sympathetic. State where the nerves originate from. State what a lesion of the Pterygoid Canal will result in. Will this lesion affect the Chorda Tympani as well?
* DEEP PETROSAL (SYMP, Internal Carotid Plexus) & GRETER PETROSAL (PARASYMP, CN VII) * Lesion of canal= Vasodilation, Lack of Secretion of Lacrimal, Nasal, & Palatine Glands, Loss of General and Taste Sensation from PALATE ***No, the chorda tympani goes to the submandibular ganglion.
300
Hyperacusis: What nerve is lesioned? What Muscle is Affected? Explain what happens with this condition
* Facial Nerve ** Stapedius m. *** Stapedius m becomes paralyzed and thus there is uninhibited movements of the stapes and consequently no prevention of oscillations--> Excess Acuteness of hearing (no protection from loud noises)

400
Name the Artery (Arteries) that Run with the nerve to Mylohyoid. Name which arteries these originate from as well.
Nerve to Mylohyoid first runs with Mylohyoid Artery (off of Inferior Alveolar Artery) then Runs with Submental Artery (off of Facial Artery).
500
A Tripod Fracture involves the fracturing of which specific bones? What specific nerve would be affected by this fracture and what symptoms would transpire.
Zygomatic Processes of the Temporal, Frontal and Maxillary bones. The infraorbital nerve (due to the location of the infraorbital foramen) would be damaged and there would be a loss of sensation to the area below the orbit.
500
What nerve (outside the brachial plexus) does C5-C6-C7 make up? What muscle does it innervate? What artery does it run with? What would injury to this nerve cause?
