Human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction (or the conversion of sound waves into electrochemical impulses) and maintains the sense of balance (equilibrium).
What are the main functions of the ear?
The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells.
What are the three main functions of the ear?
The ear has three main parts: external ear, middle ear and inner ear. They all have different, but important, features that facilitate hearing and balance .
What is the function of the inner ear in the human ear?

How human ear works explain?
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move.
What are common ear problems?

Why do we need ears?
Your ears transmit sound waves to the brain , and having an ear on each side of the head makes it easier for us to determine where the sound is coming from.
How does the ear balance the body?
Loop-shaped canals in your inner ear contain fluid and fine, hairlike sensors that help you keep your balance. At the base of the canals are the utricle and saccule, each containing a patch of sensory hair cells.
Does ear size mean anything?
Small ears indicate respect, discipline and affection . If the lower part of the ear is thick, such people are likely to be emotional. People having small ears will be shy and introverts. These traits will be more pronounced in persons having long and narrow ears.
What is inside your ears?
The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain. The fluid-filled semicircular canals (labyrinth) attach to the cochlea and nerves in the inner ear. They send information on balance and head position to the brain.
Where does your ear canal lead to?
The ear canal, also called the external acoustic meatus, is a passage comprised of bone and skin leading to the eardrum . The ear is comprised of the ear canal (also known as the outer ear), the middle ear, and the inner ear.
How can I improve my inner ear health?
- Wear your hearing aids. If you’ve been diagnosed with hearing loss and the hearing healthcare provider prescribed hearing aids as a treatment, you’ll be doing yourself a big favor if you wear them as recommended. ...

Why is the ear shaped like it is?
The folds of skin and cartilage that come to mind when talking about your ear are called the pinnae. They help capture sound waves , amplifying them and funneling them into the inner ear. These folds in the pinnae are designed especially for humans to help enhance sounds most closely related to that of the human voice.
What is the structure and function of the ear?
The pinna of the outer ear protects the eardrum from intense sound and channels the sound to the eardrum through the auditory canal. The eardrum vibrates and transmits the sound to the inner ear. The ossicles of the middle ear amplify the sound and pass the vibration to the oval window.
How the ear works step by step?
- Sound transfers into the ear canal and causes the eardrum to move.
- The eardrum will vibrate with vibrates with the different sounds.
- These sound vibrations make their way through the ossicles to the cochlea.
- Sound vibrations make the fluid in the cochlea travel like ocean waves.
