which in turn strikes a nail in the oval window in the inner ear

An important job of the auditory system is to pick up signals transmitted by sound waves. The human auditory system consists of the ear, the middle ear, and the inner ear. Sound waves enter the ear canal and vibrate the eardrum.

This causes the eardrum to vibrate. This motion sends vibrations to the middle ear and it, in turn, sends vibrations to the bones in the middle ear.These vibrations move a small lever called the hammer, which in turn strikes a nail in the oval window in the inner ear.That little nail moves the hair cells. This makes newaudition the nerve cells to produce a signal that is carried to the brain. These signals create sound that we can hear.The human ear works like a musical instrument, and our main source of hearing are the vibrations that travel through the air. They cause the sound waves that enter our ear drum and excite the organ. When the nerve endings are stimulated, they send signals to our brain. These nerve endings transmit the signals to our brain through the auditory nerve.In order to hear, you need to have a closed auditory canal. If there is a small opening in this canal, the sound wave cannot enter your ear and you will not be able to hear it. The eardrum, also known as the tympanic membrane, is attached to the bony wall of your middle ear. It allows the vibrations of sound to enter your middle ear. It is made up of an elastic cartilage (the ear drum) and a thin layer of tissue that covers it.
