The structure of ear.
00:06
There are different parts of our ear.
00:09
First of all, ear is divided into three parts.
00:12
External ear, middle ear, and then we have internal ear.
00:21
Ears divided into three parts.
00:23
So, first of all, we have a structure present in there called the orcicles.
00:29
Something present that we call it as orcicles.
00:32
Are what small bones are present small bones in the ear they are three in number that is malus incus and staves these are three bones that are present in the ear which are collectively called as the ear ossicles or or now talking about the structures involved in balance we have balancing structure present we have balancing structures present in there that is vestibular apparatus vestibular apparatus and semi lunar canals both of these are involved in balancing both of these are involved in balancing they do the balancing part for us okay then we have how these orcicles receive the signal from the external environment the the the auditory signal they receive or whenever we hear a sound how it travels down to the orocicles we have the tympanic membrane or the ear drum the vibrations reach the ear drum and the ear drum vibrates and the vibrations of the ear drum then travels down to the orcicles the signal is transmitted to the orcicles what the there are three circular passages which are present in in a different plane of space all of them are like 90 degrees to each other something like this they are present like this this structure is also present inside the air which are three circular passages these are circular in nature present in different planes this is this is known as our semi -lunar canals this is structure of semi -lunar canals okay then we have the vibrae i told you that the tympanic membrane vibrates and then reaches osicles right the last orcicle is is the maleus incus and staves when the signal reaches the steps the vibration of the steps sends the signal to a fluid sends the signal to a fluid which is present in the ear inner ear okay when the via transmits a vibratory motion to the stirrup to the fluid in the in the inner ear this fluid in the inner ear is present in like stirrup is sent the signal to the stirrup is sending the signal to the oval window the oval window is then sending the signals to the fluid in the inner area this is the this is basically the it will not directly send the orcicles will not directly send it to the fluid orcicles that is the last is the stirrup in three bones are attached that is mailus incus and tapes so steeps is stirrups then sends the signal to the oval window oval window sends it to the fluid in the inner ear.
03:47
This is, the oval window is involved in between the stirrup and the fluid in the inner area.
03:54
The passage between throat and the panic cavity is our eustachian, we also call it eustachian tube, auditory tube...
