Ears and hearing

The ears are the sense organs of hearing. They detect sounds and their properties, and where these sounds come from. What you think is your ear is actually just your outer ear. It shape help us to know which direction the sound is coming from. But in deeper, the ear consists of the ear canal, the middle ear, and the inner ear. The sound moves in the air freely. When the sound waves hit your ear they travel inside your ear canal. The waves travel on until they hit the eardrum in the middle of the ear, which acts quite like a drum. The eardrum is connected to special bones, the smallest bones of your body called ossicles. These bones transmit the waves further to the inner ear.  Your inner ear looks like a spiral full of liquid and tiny hair called cochlea. These hairs move with the sounds and transmit that information to the brain. The information captured by receptors in the cochlea travels to the brain through the auditory nerve. The brain receives and interprets this information.

If you are curious, maybe you want to know that the liquid in your ear helps your body to maintain its balance.

Nevertheless, all of this is different for aliens. The ears are the sense of sigh. They detect light so they can see shapes and colours and estimate distances. The outer ear helps them to adapt their ear canal to the amount of light it is going to receive. The inner ear is really interesting. The eyeye is like a window, because aliens use it to see the world. This light passes though the oseyeos that takes the upside down image from the retina to the brain, which must first invert it and then make sense of it. After that, the coeraye makes colour even brighter and help the ear to see things that were in a far distance. Moreover, the information captured by receptors in the coeraye travels to the brain through the auditory nerve. The brain receives and interprets this information.
