Hello students, today we'll be solving a question in biology.
00:04
As you can see from that, which of the following show the correct sequence of sound transmission in the human year? okay, so this question is about organs that are involved, organs that are involved in sound transmission, sound transmission in the human year.
00:31
So they're asking us the sequence, the correct order is, in which organs are involved in sound transmission in the human ear.
00:41
Now if you see it's obtained, it is firstly collectively carried and sent to the pinna.
00:48
Third, it is collectively sent to the pinna.
00:52
And from the pinna, it flows to a medium of empty space.
00:59
So if this is the pinna, it flows to a medium of empty space where your wax is present.
01:06
And this place that one of the earbags is present is our auditory canal.
01:16
So from pinnah, the sound slowly is transmitted to the auditory canal.
01:24
And from auditory canal, it is slowly passed to the eardrum.
01:31
Okay? there is our eardrum here and from auditory canal, this lounge is slowly transmitted to the eardrum.
01:39
And this eardrum has a membranous attachment on top called as tympanic membrane.
01:50
Okay, and next to the tympanic membrane lies the eustachian tube, but that's not involved in our sound transmission...
