Our ears help us hear and balance ourselves in space, and they have three parts.
The third part is the inner ear, which contains the cochlea, a special structure that converts sound waves into electrical impulses for the brain, as well as the semicircular canals which help with balance.
Let’s start with the external ear. The pinna, also called the auricle, is made up of cartilage that gives our ears their various shapes and sizes, and it also has a fleshy bit at the bottom- called the ear lobe, or lobule.
