Facts about the Nervous System

Everyone knows that we have five senses: sight, feel, hear, smell, and taste. We use our eyes, ears, tongue, hands and nose for this.

For our ears we have an eardrum, inner ear, outer ear, and middle ear. The tube in shich the sound goes to the eardrum is called the ear canal. Though a lot of people don't know this, the inner part of the ear has bones.

For our eyes we have a retina, optic nerve, rods and cones, and an iris.
