Cranial Nerve High Yield Points

​Cranial nerve high yield points  1. Cranial nerve which is smallest – olfactory nerve  2. Cranial nerve which enter the cerebrum directly – olfactory nerve  3. Cranial nerve with longest intracranial (sub arachnoid) course – trochlear nerve 4. Cranial nerve which emerge from posterior aspect – trochlear nerve 5. Cranial nerve which is largest – trigeminal  6. Cranial nerve with longest extra cranial course – vagus  7. Cranial nerve with longest interosseous course – facial nerve  8. Cranial nerve with longest intra dural course – abducent nerve  9. Cranial nerve with longest intra cranial course – abducent nerve  10. Cranial nerve involved in raised intra cranial course – abducent nerve 11. Cranial nerve passing through cavernous sinus – abducent nerve
