The reason why this channel is so great is because you discuss all the details, most channels don't go in depth as you do

You're probably kidding. It's medic books obvious :)

[@ayahamdan8411]

I love how passionate you are while explaining!

[@shreyaray5500]

I was procrastinating this topic for the last couple of weeks and your video got me actually interested in ear anatomy. Now it doesn’t seem all that difficult after all! You’re a blessing to medical students all over the world 💕💕

[@tarahjefferies]

I absolutely love the Ninja Nerve Videos! I'm a speech pathology student and these lectures got me through my A&P courses which will end up being a huge part of my clinical career. I'm so grateful for this free, excellent education.

[@euthanasie8017]

I'm deeply regretful that I discovered this channel in the end of my education. It's a flawless example of how teaching should be. Many thanks to you fine Sir, and the rest of the crew.

Dear Mr Ninja Thanks for your most educational presentation of Ear problems and hearing systems. I am 87 years of life and facing some hearing problem. However it’s most educative system of your explanations anyone can understand the functionality of the ear. I’m sure to follow the tips you explained in the video. In the next 2 years I will report you that I have no hearing problems. Sucha Singh

With all do respect for your hard work and expertise, this is my first time in my entire life i don’t understand your diagram of the ear because you explain them like we already know their position and where each route goes, so i got lost in the middle of the video

-The tensor tympani acts to damp the noise produced by chewing. When tensed, the muscle pulls the malleus medially, tensing the tympanic membrane and damping vibration in the ear ossicles and thereby reducing the perceived amplitude of sounds.this muscle is tensed by the trigeminal nerve'smandibular branch -The eustachian tube (pharyngotympanic tube) connects the middle ear with the nasopharynx....... It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx#### and it can equalize the pressure bet the atmosphere+middle ear via air coming out from eustach tube to the nasopharynx or reverse -Mastoiditis:-mastoid sinus can extend to the brain and affect lots of cranial nerves so if it doesn't drain into the nasal cavity it may drain into the middle ear -superior part of middle ear box is made of tegman tympani which is a very thin bone and if someone develops otitis media(middle ear infection) it can spread upwards to the tegman tympani and to the brain causing meningitis## -tensor val palatine tenses the soft palate and by doing so, assists the levator veli palatini in elevating the palate to occlude and prevent entry of food into the nasopharynx during swallowing,,may help equalize pp
