Question

The term "tic douloureux" is used to indicate the sharp shooting pain on the face, which is a result of affection of the following nerve:

• A. Trigeminal nerve
• B. Glossopharyngeal nerve
• C. Facial nerve
• D. Trochlear nerve
• E.

Hint:

Tic douloureux, or trigeminal neuralgia, is often triggered by minor stimuli and can be managed with medication or surgery.

Answer 1

The Correct Option is A

Step 1: Understanding the term "tic douloureux."
Tic douloureux, also known as trigeminal neuralgia, is a condition characterized by sudden, severe, and sharp pain on one side of the face. This condition is typically caused by dysfunction of the trigeminal nerve.
Step 2: Analyzing the options.
- (1) Trigeminal nerve: Correct. The trigeminal nerve is responsible for sensation in the face and is the most common nerve associated with tic douloureux.
- (2) Glossopharyngeal nerve: Incorrect. This nerve affects the throat and ear but is not involved in tic douloureux.
- (3) Facial nerve: Incorrect. The facial nerve controls facial muscles but does not cause the sharp, shooting pain of tic douloureux.
- (4) Trochlear nerve: Incorrect. The trochlear nerve controls eye movement, not facial sensation.
Step 3: Conclusion.
The correct answer is (1), as the trigeminal nerve is the one most commonly implicated in tic douloureux.
