Utricle - U --> the shape of the U with hair cells pointing up
Saccule - S -> shape of S with haircells pointing out
Then envision the direction of movement that would cause the prongs of the letter to sway. i.e. left to right or horizontal for U and up and down or vertcal for S

How on earth does he understand everything and is capable to explain it in such an easy way 😂?

[nannomaniac]

hello zach, i think i owe you and your team a big big thankyou as a person from a middle class family living in a place with high inflation rates someone who cant afford tuitions your channel and lectures mean alot to me, i rely on this channel for anatomy physio and sometimes biochem as well, ninja nerds was a huge part of my first year mbbs and i ended up getting distinction in each subject i dont understand local tutors at all but you're here saving my day, thank you so much

[harshitmallick]

This guy's the one saving my med studies now. Love from india♥️ Great job

This video deserves WAY more views! Thanks for sharing!

"It's so cool .I promise " this line was so motivating 👍👍👍

You are truly a blessing to all of us, medical students. I wish if i could dedicate my tuition to you and if I wasn’t a poor medical student, I would have definitely donated!! Thank you so much for your enthusiasm, i was never more excited to learn about the vestibule but your excitement is contagious <3

[lgnzxex]

literally thank you i was rewatching the same parts of one lecture for two hours and i didn't even pause once throughout this video to clarify what you said because you explained everything so well

[weehee]

Dude I just have to tell you how much I appreciate you making these videos. I'm halfway through my second year of Audiology school and your vids have been a lifesaver all along! I've watched all the ear related ones and now that I'm starting to study the vestibular system I REALLY need help. Keep it up! Much love!

I know you read the grateful comments for your job and maybe sometimes you just...but I also feel I have to thank you. I do it under this lecture because yesterday was my last exam (physiology) and my main theme to write was for the vestibular alongside semicircular canals. Also I had exchange of CO2 and pancreatic juice. The examiners were impressed how well I understod the material and I passed it with A. This whole 2nd year I was studying alone using your videos and other ones and they helped me a lot (mostly you did help me) and so again I wanna thank you your passion and great way for teaching many people like us, medics, or just curious one. Keep going with the same spirit!
P.S. I know maybe I'll be annoying but I see many people have problem with Physics. I think you should make such content, with your way of explanation all will understand the laws from the 1st time :)

[denisskenderovic]

I always watch your videos as part of my study schedule and it freshens things up and helps me a lot ! Best of luck to you good sir :D.

[federicasechi]

Watching this in 1.5x and it feels like you're on speed, loving it <3

[kimschurman]

Agreed! Your videos are my first step in introducing myself to the material and then I check out the professors notes and it makes so much sense! Thank you so much for what you are doing!

[jeremiegagnon]

Awesome video! Thanks for the recap, helped a lot!
One tiny thing though, when you break or slow down in your car, the otolithic membrane doesn't move forward because it ''makes you tilt your head down'' but because of inertia. Your cranium stops moving but the otoconias don't, which is why they move forward (toward kinocilium) and depolarize the hairy cells.

Good luck with your exams!

a good way to remember the direction of the hair cells of the utricle and the saccule is to remember that hair cells of the U-tricle are pointing U-pwards, while those of the S-accule are pointed S-idewards. :)

[renu.ritambhara]

Hey there, I am a novice with no background of science and anatomy but I am able to understand the way you explain. Making the concepts real through drawings and life examples, is especially helping me. thank you.

[leahhall]

A sincere appreciation comment from me and probably many other students - this has been the most helpful, precise and detailed explanation available to me, after hours of effort put into understanding. Thank you so much for this video!!

[georgia]

I loved this video, ive been doing an entire semester of physiology and only this video has managed to actually break it down from the beginning and explain each section and what it does and what its called. you dont assume knowledge. thank you.

As an old pilot, skier, motorcyclist I've been telling anyone that would listen, it's all about your scan, what you're focusing on and how you hold your head. Now I can see why. Thanks for sharing

You’re a great teacher. You make this stuff so interesting and fun to learn.
