Information on the ear

The ear is split up into three parts, the outer ear, the middle ear, and of course the inner ear. The outer ear is connected to the external auditory canal where the sound bounces off all the walls until it reaches the inside. Deeper inside is the timpanic membrane, the eardrum. The eardrum sends the sound to the middle ear where there are some bones that transfer the sound into vibrations and then sends it to the inner ear. The inner ear can detect accelerated movements like vibrations that enter the ear. The inner ear then translates that into something that the brain can understand.
Interesting fact
There are muscles above a horses ear that lets him turn them, humans have the same muscle but only some are strong enough to just wiggle them.
