0:00continuing with our special Senses we're
0:02looking now at the structure of the ear
0:05lots of components to the ear and what's
0:08interesting about the ear is the
0:10components are very very small but they
0:12have these huge responsibilities
0:14so starting with the outer portion of
0:17the ear this is called the Oracle or the
0:19Pena all of this here I mentioned Q-tips
0:22a lot in my lectures because a lot of us
0:24think that Q-tips are supposed to be
0:26entered here into the the structure of
0:29the ear against the eardrum to clean out
0:31the wax that is not what Q-tips are for
0:34they're really made to clean this area
0:36here which is called the Oracle if you
0:39get too close with your Q-tips just
0:41going down we have the term here
0:42tympanic membrane uh you might place
0:45your tympanic membrane at risk of being
0:48ruptured also needless to say what's
0:51inside the ear that we're essentially
0:53trying to clean out is there for a
0:55reason that is earwax clinical term for
0:58earwax would be cerumin and the whole
1:01purpose in cerumin is to trap bacteria
1:05so everything in our body really works
1:07to create its own balance and it works
1:09in our favor sometimes humans we get in
1:12the way of what our body is really
1:13trying to do natural actually so that
1:16wax buildup that you have within your
1:18ear and I'm not talking about extensive
1:20wax buildup but a light amount of wax is
1:22actually quite normal to have within the
1:24ear it is protecting your mucous
1:27membranes which your ear is also a
1:29mucous membrane so it is protecting your
1:32mucous membrane from infection trapping
1:35bacteria within the wax keeping it from
1:38entering into your station tube and into
1:41your respiratory system so you have
1:43bones within your ear called the malice
1:46the Inky's incus I'm sorry and the
1:48stapus they're located here very very
1:51small bones
1:53we can do bone transplants these become
1:56hard for some individuals over time
1:59otosclerosis is what it's called when
2:01these bones Harden they don't have the
2:04ability to repel sound back into the
2:07semicircular canals and getting it into
2:09the auditory nerves so these bones can
2:12actually be replaced by donor bones
2:14patient can regain their hearing the
2:16cochlea is what's referred to as the
2:18hearing receptor the Labyrinth is the
2:21inner ear the organ of Corti organ of
2:25hearing the main organ of hearing within
2:28the ear
2:29and then the tympanic membrane tympanic
2:32membrane is pretty important because not
2:34only does it assist with hearing but it
2:37also assists with your sense of balance
2:40and so if you have an ear infection if
2:43you have an earache fluid in the ear uh
2:47a hole in the tympanic membrane can
2:49definitely cause imbalance within the
2:52patient very very common this tympanic
2:56membrane is flexible so as it concaves
2:58in it also has the ability to concave
3:01out in the other direction it does help
3:04with producing sound waves and the sound
3:07waves vibrate what it takes in from the
3:10outside in through those bones all the
3:13way through to get to the auditory nerve
3:16to again create that connection within
3:19the central nervous system so that we
3:21have hearing and then the last part here
3:24is your station tube and the eustachian
3:27tube connects the throat to the middle
3:29ear so when you hear about your
3:32specialist ear nose and throat doctor
3:34the reason why it's an ear nose and
3:37throat doctor is because the ear the
3:40nose and the throat are all connected
3:43really within one structure
3:45so if there's fluid within the ear it
3:48would not be unfamiliar for that fluid
3:51to make its way down into the eustachian
3:53tube and cause buildup
