One of the thing i've been wondering about the tuning fork test: How come a patient stops hearing the tuning fork when it's pressed near the ear even though it is still vibrating near it (and the patient can still hear it when presented near the ear afterwards) is it because the human ear is more sensible to skull vibration than the outer sounds and the brain won't "detect" the sound near the ear or something like that?
We are designed to hear through the air. So bone conduction is less sensitive than air conduction When the tuning fork is pressed on the mastoid process, a bony prominence behind the war, that vibration is transmitted to the hearing apparatus by the bone. When that can no longer be heard, we move the tuning fork directly next to the ear, which as air conduction is more sensitive, should allow the sound to still be heard.
@@DrJamesGill kindly thanks for the answer expecting great things for what should be the next and last video about the cranial nerves based on the whole test video ^^
@@DrJamesGill honestly, i am 100% positive I can perform head to toe assessments, cranial nerve exams and gals screening, and I haven't spent a minute in med school
Tell us Dr. Gill, is it hard waking up every morning knowing that you're a legend? Is there a sense of anxiety knowing that you bear such a burden or does one simply become acquainted over time and desensitized to the raw power that you exude?
@@DrJamesGill oh by the way. I've been having a question. On my eye, i have a small yellow spot with a black stip in the middle. Is this normal or should i go see my eye doctor??
Dr James Gill Hey Dr. Gill! Wanted to let you know I made a B on it and finished the lab and lecture with a combined 85% (not great, but competitive for dental school) also finished biochem with a B. Definitely loved it more than both organics, but bummed that I finished with an 89%. Rounding up isn’t allowed ☹️ however I’m two semesters from dental school!!
I have always been mistaken in Rinnie's test the fork is to be placed anterior to the ear at the zygomatic arch. Thanks for reminding me that it's actually at the mastoid process.
It’s only a slight difference, the other benefit of the mastoid process, ignoring the fact it is a more suitable anatomical landmark, is that it removes the visual stimulus from the patient
Thank you Dr Gill for these videos. They have helped me a lot. Question: Why do we assess all the cranial nerves in a complete ear examination? What is the rationale behind examining every cranial nerve?
SSHL or SNHL....if caught early, cortisone shots into the inner ear (may) heal it. It did, with Faith in God, for my situation back in Jan thru March 2020. It was not a pleasant time at all but i made it through.
As in SSHL, a rare virus will attack the cochlea, i survived this in January, thank God. But it is rare but a real thing. Cortisone shots into the inner ear are required, expensive, painful, but worth it.
You can have viral and fungal infections. Neither would respond to antibiotics. Similarly, as antibiotics have been overused in the past there can be a lot of bacterial resistance, so the drug is no longer effective. There are other causes, but I would imagine your doctor has ruled them out
Hi Dr. Gill. I was wondering why the 512 hz (C) is chosen. Is there a particular reason for this frequency? Would a 440 hz (A) achieve a similar result?
@@DrJamesGill It would be helpful. In my case, I thought the video was great, but I know you are doing it for your students, too, so I thought I'd let you know. I think all your videos are great!

My man Dr Gill always gets an automatic like.
Vestibulocochlear is a word I did not know I needed in my life. I'm going to isolate that sound bite and make it my text alert. Really lovely.
I'm not sure why I watch so many of these videos, but I might as well go to medical school.
Well come along. We need more medics!
@@DrJamesGill honestly, i am 100% positive I can perform head to toe assessments, cranial nerve exams and gals screening, and I haven't spent a minute in med school
If there were a museum on the human body like in this video. I'd be the first to go there if I could, it's interesting stuff.
Babe i promise, i just watch Dr James Gill for the plot
I dont
Lmao
Although I’m not a medical professional, I find these videos really interesting and enlightening, that and it also helps me to fall asleep.
👍 just like my students do 😴

It's 11pm aka time to learn something that i don't need after a full day of procastination
🤣🤣
@@DrJamesGill damn... The legend has responded
I’m all about the learning 😊
@@DrJamesGill oh by the way. I've been having a question. On my eye, i have a small yellow spot with a black stip in the middle. Is this normal or should i go see my eye doctor??
I’m sorry, that is very vague. If in doubt, always please go and see your GP
I love the small quiz questions :)
I’m going to try and incorporate them more often
Any double vision?
Thank you Dr. Gill. I have my anatomy exam over head and neck in the morning so this was a great little addition to my studying
Good luck! Drop us a comment so we all know how it goes after

Those are still excellent scores!

178 likes and no dislikes. That's so right people!
Awesome vid, thx Dr. Gill.
Dr Gill do you have any advice for tinnitus? great video
Mainly distraction techniques and CBT
Great info and ASMR!

Any patient exam videos coming soon?
Not whilst in lock down. I didn’t get any filmed before the uni was forced to close, so limited to the explanation videos currently
Which is not a bad thing, as they need to be covered as well to demonstrate what is going on during the exams
Very interesting and also very relaxing ^_^
I love the fact you can induce nystagmus at home just be spinning round. It’s an easy example to get the students to do

Dr Gill could you possibly explain why someone would have a constant ear infection where antibiotics don’t work? Thank you
You can have viral and fungal infections. Neither would respond to antibiotics.

Arrow points to the anterior semicircular canal, not the 8th cranial nerve.
The structure with the "9" on it is the horizontal semicircular canal.
Thank you for that. Unfortunately I can’t update it now, but at least we have it here 😊
Just so you know, at -9:21 you said cranial nerve 7 instead of 8. (Right before you brought in the tuning fork)
Dee McDaniel rats. That’s annoying. I do with RUclips would allow you to put text edits after upload, directly on the video
@@DrJamesGill It would be helpful. In my case, I thought the video was great, but I know you are doing it for your students, too, so I thought I'd let you know. I think all your videos are great!
2:40 the sound is louder in the ear with issues?
"Commonest" or most common :)
