THE 5 SENSES
HEARING
Sound waves enter through the auditory canal and make the eardrum vibrate ( outer ear).
These vibrations make the three small bones in the middle ear vibrate. When these vibrations reach the cochlea, they are trans formed into electrical signals ( inner ear ). The auditory nerve sends signals to oue brain. The semicercular canals keep our balance and equilibrium. ( inner ear).

SIGHT
Light enters through the cornea and the pupil. The iris is a muscle that makes the pupil bigger or smaller and controls the amount of light that enters our eye. The lens focuses the light which allows the image to be project. Nerve receptors in the retina sends this information along the optic nerve to our brain. The blins spot doesn´t respond to light.

THE HUMAN BODY AND THE INTERACTION
The human body is an amazing complex machine..... It´s made up of different parts that have lots of different functions.
Our nervous system and our five senses help us to move and with the world arointeract und us.
Our five senses capture sensations and send them to the brain through the nervs. Then, the brain interprets that information and sends others to other parts of the body through the nervous system.
