Hi I’m Minh Van Tran professor of Biology at Montgomery College today we’re covering the anatomy of the ear. Let’s take a look at this model. The ear model from here to here is the external ear. This part is called the middle ear and here this region the inner ear. Now let’s go over detail of the external ear here is the Auricle this tube-like structure is the external auditory canal. This structure is called the tympanic membrane or ear drum. The external ear direct the sound into the middle ear. take a look at the tympanic membrane again the semi-transparent structure on top of the tympanic membrane visible call the email yes next to that is the incus and then the state knees I am going to show you the much larger model the three bones are called the three auditory ossicles the medias the incus and the stickies for me to learn I use the M is the list so starting from the amalias sitting on top of the tympanic membrane leather is the incus and the staties with very special features you can see the head and the base the day’s look like oval shape shape three balls are the smallest bone in our body you may want a seedless malleus incus step is M is Miss mabius Incas stay peace so here the you take into or the auditory to allow pressure equalization the oval window is at the base of these cities and you want to find a round window to directly inferior to these studies here’s a round window the inner ear it grows this semi circle canal the vestibule the cochlear cochlear smell shape scripture they have two substructures of the festival you have to open it up okay you see here the upper you shape is the utricle you you could call a break down here is a stackable both together is called a vestibule responsible for equilibrium you see the branch of nerve here it is the vestibule of branch now they come clear you want to see the spiral organ ordered fogging up call time go inside their receptors for hearing and the branch of mouth here is called the cochlear French so go together you have the vestibulocochlear nerve the eighth cranial nerve external ear here to here include the Oracle external auditory canal tympanic membrane Metal Gear auditory ossicles three bones malleus incus and stapes oval window at the base of the city’s right be hot right below the oval window is the route wyndham auditory to inner ear semicircular canals vestibule cochlear festival consists of cuticle upper part u-shape sac leo cochlear snow shapes trip to spiral organ organ alkaline receptors for hearing in here vestibule branch coakley branch look together vestibule of cochlear nerve look together vestibulocochlear nerve the eighth cranial nerve external auditory canal eardrum tympanic membrane so am innocent Glen’s auditory two elastic cartilage auditory ossicles semicircular canals the best of you all cochlea the best you do well cochlear nerve semicircular canals coakley best to be about cochlear nerve eardrum can panic membrane auditory obstacles nanos Angus stepping semi-circular canals just to be concrete nice to be well concrete married Oracle eardrum tympanic membrane external auditory canal sorry minister not auditory two elastic cartilage semicircular canals vestibule cochlea auditory ossicles malleus incus Stepan’s best to be local corner
