Oh, the Ear


The thing on your head’s the pinna it’s quite the largest part it collects the sounds from around you it’s where the hearing process starts Then those sounds go down a tunnel the ear canal is what it’s called The tympanic membrane’s at the end it’s 9-10 mm tall The last thing has another name and that’s the ear drum There’s a lot of parts to that too but it would take too long to list ’em Just look at those lobes of the outer ear Next, we’re on to the middle ear where the ossicles call home. The incus, the malleus, and the stapes are the three smallest bones The Eustachian tube is there too making your life a breeze it keeps the pressure equal when you yawn or when you sneeze Then there are two muscles: tensor tympani and stapedius. The help to move the sound along. I bet you that gets quite tedious. Balance is by the inner ear. The semicircular canals, the utricle, and saccule, keep us upright like true pals. The organ of Corti is there. The 8th nerve is too. They both move the signal along, that’s what they’re supposed to do. Those canals and that cochlea have one important detail (just one!) Have you even noticed how it looks like a prehistoric snail?
