Hello student, here the question is given and the question is regarding the human ear and we have to type or we can say tell the function about each part of ear.
00:18
So, we know the ears are mainly divided into three parts external ear, middle ear and the inner ear.
00:25
So, if we are talking starting with this stapes bone which is the smallest bone.
00:31
So, this is the stapes.
00:33
So, this is the smallest one of the middle ear and it is the main function is going to be transmit sound vibration.
00:44
So, it going to transmit sound vibration from this eardrum to oval window and this oval window is a part of inner ear.
01:01
Similarly, if we talk about the another bone which is the incus.
01:05
So, this is the another bone of this three ossicle of the middle ear and it is going to be connected this eardrum and transmit sound vibration to incus.
01:17
So, this is mainly the malleus from the malleus to stapes.
01:23
So, it mainly involve the transmission of these sound from malleus to stapes because this is the bone which present between these malleus and stapes.
01:39
So, they are going to transmit vibration from these malleus to stapes.
01:43
So, this is the main function and if we talk about this the function of these malleus.
01:47
So, it is a ossicle also for the middle ear and it is going to connected this eardrum and so it is connected eardrum and transmit sound vibration.
02:05
So, sound vibration transmit from this eardrum to incus.
02:18
So, this is the first bone after this eardrum and the transmission of this sound from this eardrum to incus then the in malleus from the malleus it going to be transfer into the stapes and this the another part which is the semicircular canal.
02:41
So, these are the part of the inner ear and we know this is mainly involved in case of balance and spatial orientation.
02:51
So, it is a involved in case of equilibrium and then the contain the response movement as well as the sensory cells are respond to send the signal to the brain and the auditory nerve, auditory nerve it is a bundle of nerve fibers.
03:13
So, it is going to carry signal and the hair cells which present inside this in the ear inner ear is going to transmit the signal from these auditory nerves to the brain cell or brain...
