    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

    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 :)

    @jeremiegagnon12925 жыл бұрын

    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!

  • @SuperIsaacVideos

    See this is what tripped me up. His physics was weird here. Do you think you could clarify things further? Imagine you have otoconias in the utricle. As you accelerate in the car, the cranium moves forward and the otoconias are dragging behind, stimulating hair cells. When you stop, suddenly the otoconia slide forward, stimulating the hair cells. Are those two subsets of the hair cells distinct? Is that how the brain decodes the direction of linear acceleration? Is the orientation of the stereocilia really the key here? Hence the utricle is only sensitive to acceleration in a 2D plane (forward back, left right), and the saccuule to a different 2D plane (up down, left right).

    I don't know. I feel like if you slammed the breaks, and your head shot forward, the otoliths would move backward. Then when your cranium stopped, they would catch up and move forward.

  • @xDomglmao

    @@jacobpickett5085 How I got it: Head = solid mass, endolymph = viscuous. When you suddenly move forward, your head manages going anterior but the pudding (endolymph) in your head doesn't yet, so it remains posterior. Since endolymph kind of sticks to otoliths, remaining posterior means otoliths remain posterior; otoliths are attached to the otolithic membrane, so they drag the otolithic membrane also posterior; otolithic membrane remaining posterior equals hair cells bending posterior. When slamming the break it's just reverse. Essentially, head moves faster posterior than otolithic membrane, so hair cells are bending anterior. Please correct me if I am wrong though. EDIT: You can skip the part with the endolymph, I just checked the Boron and it seems like it's not even involved in the otolithic organs. It's purely the otoliths' inertia that matters. Endolymph movement is only important for the semicircular canals where it leads to bowing of the cupula. EDIT2: Ok, I think I got know why it was confusing at first. The whole thing with the inertia does only apply to acceleration. If you tilt the head the otoliths will trigger ipsilateral AP firing while contralateral no AP are fired. EDIT3: "If you tilt the head the otoliths will trigger ipsilateral AP firing while contralateral no AP are fired." this is not entirely correct. Actually, e.g., even though you tilt the head to the right, even some fibers from the left side will fire. Boron has a nice pic.

    I have complete absence of signals to the brain from one saccule and suspect that I have some utricle issues too given that the car example is exactly the thing that makes me one of the most dizzy. Elevators that aren't smooth-gliding cause me major issues too when they bounce when landing on the floor. My brain also fails to compensate for my saccule's inability to send signals to my brain. This is so helpful to me in understanding my medical issue. Thank you!
