Ear

• Outer Ear consist of earlobe and ear canal
• Middle Ear consist of eardrum, ossicles, oval window, eustachian tube
• Inner Ear consists of cochlea, semicircular, auditory nerve
• Earlobe = collects and directs sound waves into ear canal
• Ear Canal = directs sound waves to the eardrum
• Eardrum (thin membrane) = vibrates according the frequency of the sound waves received and transfers the vibrations to the ossicles
• Ossicles (made up of three small bones) = amplify sound vibrations and transfers them to the cochlea
• Oval Window = collects and transfers sound vibrations from the ossicles to the cochlea
• Eustachian Tube = balances the air pressure on both sides of the eardrum
• Cochlea (contains fluid) = detects and converts sound vibrations into nerve impulses
• Semicircular canals (contain fluid) = detect the position of the head and help to balance the body
• Auditory nerve = sends nerve impulses from the cochlea to the brain to interpreted
