Definition: The organ of hearing, consisting of the pinna, auditory canal, eardrum, malleus, incus, stapes and cochlea.
Alright class, settle down now, let’s take a peek,
At what “ears” really mean, if you please seek!
The dictionary gives us a list quite grand,
Of parts inside your ears, across the land.
Let's break it down with rhymes, to make it clear,
And banish any lingering fear!
First we have the
pinna
, so proud and bright,
That’s the outer part – catching sound with light!
It’s shaped like a cup, you see, a lovely form,
To gather every whisper and storm.
Next is the
auditory canal
, long and deep,
Where sounds travel down, secrets to keep.
Like a little tunnel, guiding with grace,
To bring the music to your listening space!
Then comes the
eardrum
, thin and so slight,
Vibrating quickly, day and through night!
It feels the sound waves, a delicate dance,
A crucial player in this sonic trance.
And now we have bones – a marvelous crew,
The
malleus, incus, stapes
– strong and true!
They’re called hammer, anvil, and stirrup you see,
Passing the sound with amazing glee!
Finally, deep inside, a coil so neat,
The
cochlea
, where hearing is complete!
It translates vibrations to signals bright,
Turning sound into feeling, pure delight.
So there you have it, class, don't be slow,
A whole system working, helping us know
The wonders of music and voices so clear,
That’s what your ears are for, far and near!
Do you have any questions? Don't hesitate to ask,
Let’s learn about hearing – a wonderful task!
