&text1=Sound waves are channeled down the ear canal by the pinna. The sound waves cause the eardrum to vibrate, which in turn moves the three bones (ossicles).&
&text2=The movement of the ossicles amplifies the vibration, which is sent through the oval window and into the cochlea.
&text3=The vibrations cause fluid inside the cochlea to move across a membrane.
&text4=Specialized hair cells inside the cochlea translate this movement into electrical impulses, which are transmitted to the brain via the cochlear nerve. The brain interprets the electrical signals as sound.&
