How do our ears work and eyes work?
Eyes works and seeing
Seeing is the most important sense because it gives you images of the world and what is happening around you. Not only do you see with your eyes, but also with your brain. Your eyes sense light and send signals to your brain, which they classify to create the full-color and animated 3D images you see. Eyes are very important organ in terms of understanding things.
This is how your eyes work
Light, springy objects penetrate the eyes through a transparent window on the front, known as cornea. It then passes through an opening, the pupil and the flexible lens that focuses the light on the retina in the back of eyes. From there, the signals are sent to the brain along the optic nerve.
Lighting control
The muscles in the colored part of the eye called the iris which controls the amount of light that enters the eye by changing the size of the pupil. In bright light, the iris makes the pupil smaller so that less light falls so as not to dazzle you. In low light, the iris widens the pupil and lets in more light so you can see well.
Track and Scan
Eye movement is control by the six small muscles. They are attached to the eyeball at one end and to the skull at the other. In between, they move the eyeball very precisely up or down, outwards and inwards. Wider movements allow the eyes to follow moving objects. Smaller moving objects like faces.
Sound sensors
When you make noise, you send sound waves through the air. These are picked up by your outer ears, which direct the vibrations inward. Signals are sent from your ear to your brain that allows you to hear sounds and communicate through speech.
Sound of waves
Sounds are made by something that vibrates and moves like waves through the air. How did it happen? Imagine pushing one end of a spring. The coils on the pushed end are compressed and then separated, pushing the coils further, creating a compression wave. Together with sound, vibrations send air molecules together, causing waves to drift away from the source.
How do your ears Work
Our ear contains 3 parts, one is outer area, second is middle ear and third is inner area. Sound waves enter your ear along the outer ear canal and hit thin skin like the ear drum, causing it to vibrate. These vibrations are transmitted to three small bones called ossicles that run through the middle ear.
You move back and forth, pushing and pulling on the oval window, a membrane at the entrance to your inner ear. This sends waves in the form of a snail through the fluid in spiral tubes of the cochlea. Tiny capillary receptors in the cochlea convert the wave into nerve signals that are sent to the brain. The inner ear contains the vestibular organ which is responsible for balance.
To keep balance
Your ears allow you to hear sounds, but they also give you a sense of balance. Special sensors in each inner ear inform your brain of your upright position so you can tell your body how to balance itself. Without your ears, you’d fall off your bike.
Sixth Sense
Your body has a sixth sense that automatically keeps you upright. Balance sensors in your ears send signals to your brain. These are supported by information from your eyes as well as position and pressure sensors in your muscles, joints and skin. Your brain processes all of this data and sends a flow of instructions to your muscles to help you balance yourself.
Feeling dizzy
The balance sensors in your ears are based on a fluid-filled tube system. It works great all the time, but when you’re walking through an amusement park the liquid gushes in the tubes and it takes a while to stabilize once it stops moving. As a result, the sensors in the tubes send a lot of confusing information to your brain confusing your location. This makes you dizzy.
Losing Balance
Different systems in the body work together in your sense of balance. When you remove parts of it, like your eyesight, the solid ground under your feet, or two legs to support your body, standing becomes much more difficult; You could lose your sense of balance and fall. Try covering your eyes with a blind crease and stand on one leg to try it out for yourself.
