Parts of the Ear Worksheet - My Schoolhouse - Online Learning
Sound waves enter the outer ear. They travel down
the ear canal and make the eardrum vibrate. (The eardrum is a thin skin
that stretches across the inner end of the ear canal.) The
vibrations of the eardrum cause vibrations in the three little bones in
the inner ear. These little bones vibrate a spiral-shaped organ
called the "cochlea." The cochlea is filled with liquid
and tiny hairs. Each hair has its own connection with a nerve that
goes to the auditory nerve. Auditory means hearing. The
auditory nerve sends a signal to the brain.
