 Okay, so now we're looking at the inner ear. So this is just a large version of the inner ear So those ossicles from the middle ear as the tympatic membrane vibrates as sound waves hit it It's gonna vibrate those ossicles which is gonna vibrate into our vestibule here And those about those sound waves come into the cochlea, which is this kind of snail-like structure over here inside that is Your cochlear ducts so you can see those holes there Okay, on the other side, so we have that vestibular cochlear nerve So you have two branches of the vestibular cochlear nerve the cochlear branch and the vestibule branch Of course the cochlear branch goes the cochlea the vestibular branch goes over to the vestibule our bony labyrinth is kind of surrounding layer here Of all these bones that surround it Okay, you have your semicircular canals on this side of it So our semicircular canals I think of them kind of as an x y and z axis So it's what's giving us our coordination. So if you get vertigo or something like that It's a problem with this part of the inner ear The bony labyrinth is actually made up of these membranes here on the inside We've got three distinct regions of these membranes here They're kind of swollen parts of that membrane themselves. You have the saccule the utricle and the ampula
