What is an Ear

Our ears are one of the most complicated organs of our human body. You have an outer ear, a middle ear and an inner ear. The outer ear is the visible exterior part of the ear with the ear flap or pinna and auditory canal. The middle ear consists of the eardrum and three very small bones. These are the hammer and anvil and the stirrup.

The oval window forms the partition between the middle ear and the inner ear. The inner ear consists of the cochlea, which is filled with liquid. Inside the cochlea are sensory cells with thousands of extremely tiny hair cells.
