Question

Which of the following group of cranial nerves control eye movements?

• A. IV, V and VII
• B. V, VII and IX
• C. I, II and III
• D. III, IV and VI

Hint:

Remember eye movement nerves as: LR6, SO4, all others by 3.

Answer 1

The Correct Option is D

Step 1: Understanding eye movement control.
Eye movements are controlled by extraocular muscles, which are innervated by specific cranial nerves. Proper coordination of these nerves allows precise movement of the eyeball.
Step 2: Cranial nerves involved.
Cranial nerve III (Oculomotor) controls most eye muscles.
Cranial nerve IV (Trochlear) controls the superior oblique muscle.
Cranial nerve VI (Abducens) controls the lateral rectus muscle.
Step 3: Analysis of options.
(A) IV, V and VII: Trigeminal and facial nerves are not involved in eye movement.
(B) V, VII and IX: These nerves control facial sensation, expression, and swallowing.
(C) I, II and III: Olfactory and optic nerves are sensory, not motor for eye movement.
(D) III, IV and VI: Correct group controlling eye movements.
Step 4: Conclusion.
Eye movements are controlled by cranial nerves III, IV, and VI.
