Why do children have ear infections?

Children are more likely to have ear infections like otitis media that come from bacteria or viruses than adults because of their developing ear anatomy. The middle ear is connected to the back of the nose by the auditory tube (also called the eustachian tube) and its location allows easier access to germs. This may lead to a buildup of fluid and pressure, painful infections, and even hearing loss. Infections in children can affect early speech and language development.

Why do people lose their hearing?

There are diseases, infections and cancers that affect specific parts of the ear and can lead to hearing loss in children and adults.

Where does sound travel?

Sound travels through the auricle and the auditory canal, a short tube that ends at the eardrum. Sound entering the outer ear travels through the middle ear and causes the eardrum and ossicles in the middle ear to vibrate. As it travels, it amplifies (gets louder) and changes from air to liquid.

How do the brain and auditory system work together?

The brain and auditory system work together to control how we hear and how we balance ourselves. The human ear is a complex organ and many scientists consider hearing to be the most complex of the human senses.

A middle ear infection often results in the accumulation of fluids in your middle ear. Pressure from these fluids can cause the eardrum to rupture. Barotrauma.

What happens when sound waves strike your ear?

Hearing. When sound waves strike it, your eardrum vibrates — the first step by which structures of your middle and inner ears translate sound waves into nerve impulses.

Where is the eardrum located?

Eardrum/Tympanic Membrane: It is the thin membrane located between the external ear canal and the middle ear.

Which part of the ear conducts sound?

The ossicles in the middle ear do the job of amplification. Then the cochlea in the inner ear conducts the sound through a fluid. Cochlea is a complex part of the ear, which takes the physical vibrations caused by the sound waves and translates them into electrical information for the brain to recognize as sound.

How do sound waves travel through the ear?

The sound waves travel first through the ear canal and vibrate the eardrum. Before the sound waves enter the inner ear, the total pressure must be amplified. The ossicles in the middle ear do the job of amplification. Then the cochlea in the inner ear conducts the sound through a fluid. Cochlea is a complex part of the ear, which takes the physical vibrations caused by the sound waves and translates them into electrical information for the brain to recognize as sound. The organ of corti which contains thousands of tiny hair cells, when moved, sends electrical impulses through the cochlear nerve. The cochlear nerve then passes these impulses to the cerebral cortex and the brain interprets them, and we get to hear.

What are the three bones in the middle ear called?

Auditory Ossicles: The three small bones in the middle ear, called malleus, stapes, and incus, are connected. These bones together are called the auditory ossicles, and their purpose is to let the sound that strikes the eardrum, further into the inner ear.
