Human Anatomy |
On average, people can hear sounds in the frequencies between 20 to 20,000 Hertz.
|
anvil - (also called the incus) a tiny bone that passes vibrations from the hammer to the stirrup. cochlea - a spiral-shaped, fluid-filled inner ear structure; it is lined with cilia (tiny hairs) that move when vibrated and cause a nerve impulse to form. eardrum - (also called the tympanic membrane) a thin membrane that vibrates when sound waves reach it. Eustachian tube - a tube that connects the middle ear to the back of the nose; it equalizes the pressure between the middle ear and the air outside. When you "pop" your ears as you change altitude (going up a mountain or in an airplane), you are equalizing the air pressure in your middle ear. hammer - (also called the malleus) a tiny bone that passes vibrations from the eardrum to the anvil. |
nerves - these carry electro-chemical signals from the inner ear (the cochlea) to the brain. outer ear canal - the tube through which sound travels to the eardrum. pinna - (also called the auricle) the visible part of the outer ear. It collects sound and directs it into the outer ear canal semicircular canals - three loops of fluid-filled tubes that are attached to the cochlea in the inner ear. They help us maintain our sense of balance. stirrup - (also called the stapes) a tiny, U-shaped bone that passes vibrations from the stirrup to the cochlea. This is the smallest bone in the human body (it is 0.25 to 0.33 cm long). |
