[@morgan2852]

best teacher ever. I should be paying you instead of my schools tuition.

[@alinstoleru7703]

Man, this is like the best channel in the entire world. I don't know how to thank you enough for the effort you put into making this amazing videos. You're the real mvp man!

[@deeskeete581]

I totally agree with u here, such a breeze!!!

[@alexioffe8523]

Man, I swear, after I graduate medschool from Germany, I wanna go to Switzerland and some of the money saved on taxes will go to Zack!

[@alexioffe8523]

He has patreon, I will support the guy there

[@asthetic3415]

[@EricHumphries83]

Lol for real

[@qirongdu5184]

You explain clearly about mechanism of hearing, it is the best lecture I have listened, thank you!

[@mahadali619]

I see what you did there

[@yudong5030]

Same here

[@tonyzachariah9874]

I usually don't comment on videos , but I cant stop from appreciating how much I love your method of teaching. I can see your passion and finally those diagrams are really next level!! btw thanks a lot

[@Bobette0123]

you know it'a a great lecture when you get distracted by the lecturers knowledge. I catch myself thinking about how he knows so much and how he knows how to communicate it so clearly! thank you for sharing your gift, 100/10 human!

[@The_Vhibe]

You are a GODSEND. For someone with a non-science background coupling your lectures along with my lectures just helps with this content. I am beyond grateful for your effort, time, and knowledge that you grace us with. For anyone who thinks they "CAN'T LEARN SCIENCE" please try to carve out a little more time and add these to your lectures/study and it will help.

[@ethancastanon811]

Lecturer is a genius. I can't believe how many videos he has produced.

[@SS-se2mb]

I have never watched a video where i don't lose interest easily in whatever i'm watching whatever the content is, but man your videos pass by so quickly and i actually enjoy all of it wanting to learn more. Thank you so very much for your hard work it's greatly appreciated

[@abodyphone7]

You deserves more than 1 milion subs , very well explained lecture

[@FlapFlapOctopus]

This is so great! I am a graduate Audiology student and this served as a great review for my classes. It’s usually pretty hard to find videos online that go into this much detail. Thank you!

[@eliyamadey5764]

So great indeed!

[@呂文翔-m1j]

indeed

[@h.mgillan4681]

You're the BEST teacher there is, how you give the bigger picture before diving into the details, aaaahhhh love it, I can't remember how many times I have said 'woahhh' when I relate concepts and link things while watching your videos aaah, thank youuuuuu for existing

[@rishitabiswas2388]

All hail Ninja Nerd! This is, hands down, the BEST channel. Zach Murphy is always to the rescue. Can't thank you enough for explaining in such great detail!

[@josetrujillo738]

Boom! Roasted! Sweet! Deal! Thank You Zach! Thank You Ninja Nerd Lectures!

[@zee02x]

LITERALLY WOW. Thank you. i'm so so grateful.

[@corbywhite4662]

You manage to answer my questions before I even start wondering! You explain everything with a great pace and reasoning, that it does not have to be a doctor to understand! Bravo!

[@aguchinemerem8726]

I'm a final year medical student and I discovered this channel just recently to help my knowledge of internal medicine. You are the best, I wish I had known you during my 3rd year when I did neuroanatomy and neurophysiology. You're so good at teaching!

[@amohamedhassan2011]

Dude you’re amazing! I like you! Don’t stop making videos please. We support you!

[@LiederGern]

Wow, man you are the best teacher ever. You don’t hide your wonder of the mechanism, and I think that’s why you explain it so well. If only all anatomy/physiology teachers could be more like you!

[@jessstivers2113]

I can spend weeks trying to learn some convoluted topic, watch one of your videos, and instantly understand it. I need to stop trying so hard to grasp things on my own, and come to you first instead. Thank you so much for the work you put into your videos!

[@ness3082]

the videos on your channel have saved my academical life since highschool, but especially now in university. Your way of teaching is absolutely amazing. So grateful for all the work you put into this channel

[@revnext4370]

It takes guts to go , all from scratch , not one image copied from any source.. and explain the most advanced anatomy of the human body , so efficiently .. Hats off sir!!

[@Yasmin-qh5ig]

You’re saving my corona online semester hahaha 😂🙌🏻

[@mari0o0ma15]

same lol

[@mikasaakrman7114]

Are you medical students? From any country?

[@rauminah.g]

i wanted to say a lot out of gratitude.. But all those sums up at "thank u so much from the core of my heart"

[@simuncrnkovic2612]

I am medical biochemistry student, but our proffesors expect us to learn physiology like doctors so I found you and everything is so clear now, thanks a lot!

[@jennifers9513]

We seriously need more teachers like you. I have had multiple anatomy teachers over the years. Every single one of them have fit a description. I feel, they have all used big complicated nomenclature and terms JUST to confuse us. This semester, I am writing down all of the confusing phrases and I plan to submit it with my exit survey, to show how awful the class was. Thank goodness for online classes and transcription programs, I am able to capture the actual word order. It is maddening. You Sir, have made learning about this topic EXTREMELY interesting and understandable. I love your teaching style; the repetitive use of the terms, the conversational way you explain the structures and nomenclature. I look forward to all of your videos to help me through these classes. Thank you for creating.

[@rekrapone6750]

When, I started this, I needed an angle of attack too make my point clear. I was born terminally-ill, a S.I.D.S. baby who lived with severe epileptic-seizures with sever asthmat and crippled legs. I was supposed too have died at age 6. I am 50, now, snuck into the USN and USAF, before, I was 30 y/o. No plans, Hi, they call me Little Jim. I'm not perfect or cool. I am alone.

[@kovalchuk71]

As a medical student, this video helped me tremendously! Thank you for taking a complicated topic and making it incredibly easy to comprehend.

[@smokyhs2]

Dr Zach is golden, he should be preserved at all costs, what a highly knowledgeable person with a fine ability to transduce complex physiology into simple easy to understand parts.

[@_Marea_]

i adoooooore this guy's explanation 😭😭😭🥰

[@manolyjativa1496]

Thanks!

[@jillianklaus8038]

We cannot thank you enough!! You made it so easy to understand and LEFT NO CRUMBS!! I was following along, making my own diagrams and at the end when it zoomed out to the whole board, I was like "woah... i understand all of that"

[@parinithamaben4141]

So beautifully explained! Love how passionately you teach and how easy you make it for us to understand. Thank you!🙂

[@marmar-u4t]

Just to clarify on outer hair cells. Just like inner hair cells, outer hair cells also have K+ channels and tip links. When the endolymph moves, both hair cells types move and both cell types have a surge of K+ into the cell (depolarization). HOWEVER, the difference that in outer hair cells the depolarization changes the membrane potential and that causes prestin to relax and elongate the cell. This is STEP 1 of the process. The second step would be the release of ACh from the olivocochlear bundle, which like Ninja Nerd said hyperpolarizes the cell by letting K+ exit the cell. This causes prestin to contract so that the outer hair cell returns to its original shape to be ready for the next cycle. This video was PHENOMENAL as all other videos, but I just wanted to add a side note for those who want to know the chronological order of the outer hair cell function.

[@serenesaju1343]

YOU ARE JUST OUT OF THIS WORLD IN EXPLAINING THE CONCEPTS SO CLEARLY!!!!!

[@kirandey1744]

I have been a student of audiology for last 5 years now...currently post grad year 1 this is the 1st time someone actually explained this to me. I am so thankful for your videos ❤

[@madihrazzaie4341]

OMG, You are the best teacher I have ever seen regarding explaining ear anatomy and physiology. THANK YOU

[@mohamedkoraichi8927]

so.... my promotor made me watch this video in order to understand the inner hearing complex and the functioning of the organ of corti. I have to say ... I'm watching this @ 4 in the morning and it is the best explanation I've heard ! you're a lifesaver !

[@ДиёрбекАбдуллоев-ъ7я]

Although we are studyingat the meduniversity in our own country but this man is teaching us anatomy from the beginning of the semester. I dont realy know how to thank to him. He makes very amazing and magnificent videos which are very understandable. Thanks a lot

[@tanayashah2514]

Each time I watch your videos…..My love for physiology increases even more …..thank you !

[@YingTing100]

i was so confused by my school's lectures and this was such a lifesaver. thank you for the clear explanations of the concepts!

[@claralollypoppy]

[@ELFCloudGamer]

My uni literally teaches us nothing so I am so so grateful to you!

[@kousar1233]

ELFCloudGamer 😂😂😂

[@m.z.6990]

I never comment on youtube but you are honestly the best teacher! Your presentations are so clear and fun. I dont know what I would do without your channel!

[@mohamedhosny3846]

Man, what a amazing you are !!! i have no words to say,, i am Otolaryngology specialist, and i learned so much from your videos,, god bless you. you deserve the Oscar of medical teaching.

[@joyceoie]

I have ADD and doing MSc in Audiology with only a shallow background of biology. The enthusiasm from the lecturer is what captures my attention and OMG I learn more here than sitting through 9hrs of lectures in school 😭😭 thank you!!!!

[@sunandaringangaonkar1300]

The most wonderful explanation I ever watched.You must be a very good teacher. Simply wonderful.

[@godwinlinus1547]

You're just making my medical school so simple, thanks a lot

[@nishidhsinhjadav7818]

I am fortunate to have a teacher like uhh. The topic which i was skipping several times in previous years became the one of my favorite topic at present..... It is only because of you.... Thanks a lot for explaining us in such a beautiful way.... U are Genius......

[@AndJusticeForAll...1985]

Lovin it. Just had a doctor mess up my Eustachian tubes and now I have PET. It's amazing how interesting these different parts of the ear are. I love it

[@Shreyaroy3819]

This video is a big help. Finally understood the cochlear structure and mechanism of hearing clearly. Its like peace in my mind finally understanding the structure and mechanism. Literally nobody explained this topic like this the way you did.Big big thank you sir.

[@legs_11.82]

Great video man, really enjoy watching your videos when i struggle to understand my lecturer or text book. I love how you take 3 or 4 steps forward and take a couple back as a re-cap as you move through things. Cheers

[@jaygala9420]

There are our professors who taught this by just simply reading presentations although we paid lacs of rupees on them and here you are teaching this so nicely and putting infinite efforts for someone you don't know and that too free of cost is really really appreciable and respectful. Thank you so much Zack sir. You will be the ONLY reason because of whom I pass with good grades in exams. I literally draw and write what you say in the exams and the professors also get shocked. Your efforts and contents are really good. Once again thank you so much sir. Proud to be your student.💯

[@kadidiaouologuem8171]

Wow!!!! Unbelievable .I just learned in less than 15minutes what I tried to figure out for a whole day. Very detailed explanation. May God bless you sir.

[@ysgb6543]

He is the God of the whole medical science! The way he makes all these concepts understandable is unbelievable!

[@hannahburkert8742]

Thanks for this great video! Just wanted to say that there is NO kinocilium in the Cochlea, but only in the vestibular organ. The kinocilium disappears after maturation and only stereocilia are left. Anyways, you do such an amazing job! Thank you so much

[@ghazalamfarrukh1769]

Yes macula and Stria have kinociliym BUT guyton also states their presence in organ of corti too

[@asohrichardson7619]

My goodness, Prof Zack you deserve a gold medal. You're making my med school life so sweet🥰🥰💖

[@bungaramadhani5055]

best medical school lectuureee channel:")

[@Gabriel-yc1kx]

At 04:17 In the scala media, the structure responsible for secreting K+ ions is the stria vascularis (not medullaris)

[@caraeisert4660]

I study medicine in Germany - one video of yours is better than 5 lectures of my professor - loving - enjoying - celebrating medicine!

[@dalian7111]

Good job man, struggled to get my head around this for a while. Also love your enthusiasm, makes the subject more engaging.

[@supratikbiswas8514]

You're a God-gifted teacher! Your channel contents always make us realise that the best things in the world are always for free. Thanks a lot for saving our semester!

[@larkspur52]

Wow. I’ve watched and taken notes on the lectures, read and carefully notated my textbook and then watched your video. You explained everything SO MUCH BETTER! I think my book and lectures only brought 1/3 of the knowledge that your video did!

[@colestephens2848]

You're the goat man. Your videos have helped me in my medical school courses so much!

[@lvbianchi31]

I was ready to cry until I saw your video, then I finally understood the concept! You explained it so well. Thank you.

[@josetrujillo738]

Never gets old! Watching and listening to you teach is very nice! Thank You!

[@manolyjativa1496]

It must have been so hard for past generations of med students to study without your help, thank goodness we have you❤

[@mikewilkinson1137]

You are the man! If I had this type of instruction when I was in grade school, college, I would be the man as well! Thank you!

[@sunnyskies3707]

I love how you repeat key points over and over to really make sure we understand

[@yashbhadauriya3207]

I like the way you use different color pens .....it just boosts up our concentration and gives an artistic touch to your teachings

[@alexandreribeiro142]

You're doing great valueable content for humanity. This is gold

You are a great teacher. I am just a High school student, who was confused between Bony Labyrinth and Membranous Labyrinth. Your teaching style got me to watch full 41 minutes lecture.

[@Updula]

You are not just a teacher you are a miracle on earth.

[@sarahblack8913]

I found this so helpful! Trying to learn out of a text book is difficult for me - having someone explain the concepts clearly And with diagrams helps me so much :)

[@maheshgolla8945]

No words to describe the way of your teaching...... Loved it..!
