Why Sound is 'Music to Your Ears'!
Imagine possessing a tiny musical instrument less than an inch long (2.5 centimetres). An instrument so sensitive it can translate every note and every sound your mind can perceive. This amazing instrument is your ear.
Internally, your ear has a drum joined to a trio of tiny bones which in turn 'play' a harp which floats in a ball of liquid. As sound waves strike your eardrum, it vibrates. This sets three little bones vibrating in your middle ear. The third one strikes against an 'oval window' that seals your inner ear - vibrating at the same speed as the eardrum but 20 times harder.
Your inner ear is an intricate network of passageways securely encased in bone and filled with fluid. It has a 'hallway' that coils around like a snail's shell. This is called the cochlea (from the Greek word for 'snail'). The cochlea contains the endings of your auditory nerve, which sends impulses to your brain.
Your actual sense organ of hearing, the organ of Corti, is an amazingly complicated structure present only in mammals. This miracle of design has thousands of minute arches placed side by side to form a tunnel, with thousands of inner and outer hair cells.
The function of hair cells is not to move, but to be moved. They convert a mechanical force (being pushed sideways) into an electrical signal which proceeds to a nearby nerve ending and so to the brain. Each hair cell responds only to a small range of stimuli (information from the environment).
Besides helping you hear, your ears also help keep you balanced. As your head moves, your brain analyses the way the fluids in the inner ear move in relation to gravity. This keeps you aware of your body's position even in the dark or when your eyes are closed. If you quickly spin around, the liquid in your inner ear spins and momentarily upsets your brain's perception. This makes you feel dizzy.
Each of your ears contains as many 'electrical circuits' as the telephone system of a fair-sized city. Could this remarkable miracle of design in your ears have 'evolved'? If mammals evolved from reptiles, for example, where did the three little bones in the middle ear (the hammer, the anvil, and the stirrup) come from? And where did the organ of Corti come from? Mammals possess this incredibly complex organ, yet no reptile has one. Why would the tens of thousands of parts in the organ of Corti evolve in an ear that was functioning without it? The answer of course is that ears did not evolve. Creatures which had supposedly evolved without them would not have known there was anything to hear anyway. Ears are such marvellously designed and perfectly functioning organs that they could only have come complete from the Master Designer, Jesus Christ the Creator, at the time of creation.
