Describe the pathway of sound from the point where it enters the outer ear to the point in which the sound information travels to the brain. briefly describe the structure and function of each organ along the pathway. @coldstare

When you first hear a sound, it travels to the auricle (which is also known as the pinnae). That is the part of the ear you can see you the human eye. It then moves through the ear canal, until it reached the tympanic membrane (also known as the eardrum). When it reaches the ear drum the noise starts to vibrate. Than alerting the three tiny bones within your inner ear called the ossicles. These bones have names of course. they are called the malleus (which is known as the hammer), incus (which is known as the anvil) and stirrup (which is known as the stapes). When the ossicles moves the fluid in the cochlea, the tiny hair that is in our ears (I know gross right) then lets the brain know. The process seems long, but happens so quickly within our body.
