When your eardrum vibrates, it is responding to sound it has heard. Then, it send a signal to your brain telling your body to react.
the ear helps to hear by reciving the sound waves which makes the eardrum vibrate at the same time sendind signals to the brain for interpretation.
Focuses the sound and the direction of the sound. :)
It acts like a dish, capturing more sound than if there was no ear there, then on the inside there is the eardrum that vibrates with the sound waves which your brain then interprets.
Outer ear
The middle ear, outer ear, and inner ear are the three parts of the ear.
In the ear structure there are hollow channels in the inner ear which contain fluid. The outer ear receives pressurised sound waves from the external environment, they are carried to the inner ear and causing ripples in the fluid, tiny hair cells detect this and carry the signal to the brain via the auditory nerve. This is then interpreted by the brain and the sound is "heard" by the organism.
the anatomical name for outer ear is PINNA,The anatomical name for ear is OTO, e.g., inflammation of ear is OTitisENT a branch of Surgery is Ear Nose and Throat also called as( Oto rhino laryngology )Oto : EarRhino : NoseLarynx : ThroatExternal ( outer ) ear is also called as Pinna ( auricle ),The inflammation of outer ear (pinna) is also called as Otitis externa
Nothing
The outer ear helps funnel sound (vibrations) into the inner ear, increasing the number of quieter things you can hear.
You don't hear anything. They don't actually have to get there through the outer ear. If your ear is plugged, or if your 'tympanum' (ear drum) is broken, the vibrations can conduct through the bone that you feel behind your ear. But they do have to get to the inner ear somehow. If vibrations don't reach the cochlea in the inner ear, then you don't hear anything.
Your outer ear would sag or hang making it harder to hear.
Sound waves are collected at the outer ear.... it funnels the sounds into the ear canal
Sound is picked up by the outer ear and is sent to the middle ear. It is amplified and enters the cochlea which allows us to hear.
The outer ear works by making things loud enough so you can hear something. have you ever rolled your ears up and all the noises around you got louder? That's why.
The three sections are the outer ear, middle ear, and inner ear. There are links below to the images of the ear's anatomy.
Three bones in your ear hammer, stirrup, anvil.
to transmit sound entering the outer ear to the bones of the middle ear
the stirrup connects to the outer ear to the inner ear
It does not help for any person to cut his hand behind his ear.
well... if you see the fish's ear on the outside then it has an outer ear but if not then the fish has an inner ear.
