Question

"Patient: 57-year-old woman

Chief complaint: ""My tongue really hurts. Especially in front, at the tip. It gets worse as the day goes on and when I eat it's really bad. The roof of my mouth also hurts. Also I can't taste it as well. I move my food to the back of my mouth so I can taste it. Sometimes I can't sleep at night because of it.""
Background/Patient history: Patient reports burning sensation on tongues for past several months. No history of injury.
Current findings: Unremarkable. You suspect burning mouth syndrome and recommend further tests.

Which nerve transmits pain from the roof of the patient's mouth
a. CN V2 (anterior superior alveolar nerve)
b. CN V3 (lingual)
c. CN V2 (greater palatine nerve)"

Answer 1

The greater palatine nerve (CN V2) transmits pain from the roof of the patient's mouth.

Step-by-step explanation:

The nerve that transmits pain from the roof of the patient's mouth is CN V2 (greater palatine nerve).

The greater palatine nerve is a branch of the trigeminal nerve (CN V). It innervates the mucous membrane of the hard palate and transmits pain sensation from that area to the brain.

In the given scenario, the patient reports pain in the roof of her mouth, which suggests involvement of the greater palatine nerve. This could be due to various causes, such as oral infections, injuries, or inflammation. Further tests can help diagnose the underlying condition causing the pain.
