Interesting facts about testing 9th, 10th and 11th Cranial nerves

Hey guys!
So here's my first blog! Hope you like it!

Did you know that when 11th cranial nerve is involved on one side, you check for turning of head to opposite side and shoulder shrugging on the same side?

But when involved bilaterally, the patient can't turn their head.

So to test bilateral sternocleidomastoids, you ask the patient to sit up from sleeping position. He'll have head lag!

Here's another interesting fact:
Gag reflex is involved in 9th or 10th cranial nerve nerve palsy... This specifically localises lesion at medulla because both nerves originate there.

That's all!
Thanks ☺
