Question

Cranial nerve i is also called pneumogastric, ii is also called vestibulocochlear, and iii is also called Dentist's Nerve.

• A. i - Spinal accessory, ii - Olfactory, iii - Vagus.
• B. i - Vagus, ii - Auditory, iii - Trigeminal.
• C. i - Facial, ii - Abducens, iii - Glossopharyngeal.
• D. i - Pathetic, ii - Hypoglossal, iii - Vagus.

Hint:

Quick recall: Vagus = Pneumogastric, VIII = Auditory, V = Dentist's nerve.

Answer 1

The Correct Option is B

Concept:
Cranial nerves are named based on their function and location, and many have alternative names.

Step 1: Identify pneumogastric nerve. The pneumogastric nerve is another name for the Vagus nerve (X cranial nerve), which supplies thoracic and abdominal organs. \[ \text{Pneumogastric} = \text{Vagus nerve} \]

Step 2: Identify vestibulocochlear nerve. The vestibulocochlear nerve (VIII cranial nerve) is also called the Auditory nerve, responsible for hearing and balance. \[ \text{Vestibulocochlear} = \text{Auditory nerve} \]

Step 3: Identify Dentist's nerve. The Trigeminal nerve (V cranial nerve) is called the Dentist's nerve because it innervates the face and teeth. \[ \text{Dentist's nerve} = \text{Trigeminal nerve} \]

Step 4: Match with options.
• (B) i - Vagus, ii - Auditory, iii - Trigeminal → Correct \checkmark

Step 5: Conclusion. \[ \text{i = Vagus, ii = Auditory, iii = Trigeminal} \]
