What is the part of the ear that is visible?

The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.

What is the most visible part of the ear?

The auricle or pinna is the most visible part of the outer ear and what most people are referring to when they use the word “ear.” Middle ear: Three tiny bones — the malleus, incus, and stapes — within the middle ear transfer sound vibrations from the eardrum to the inner ear.

How ear works in our body?

Here is how the ear works normally: 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 bones causes the fluid in the inner ear or cochlea to move.

How can ears be damaged?

Things like a cotton swab, fingernail, or pencil can scratch the ear canal or cause a tear or hole in the eardrum (called a ruptured eardrum). Direct blows to the ear or head. Falls, car accidents, sports injuries, or fights may tear the eardrum, dislocate the ossicles (tiny ear bones), or damage the inner ear.

Can ear damage heal?

Damage to the eardrum is known to be common after large blasts, but this is easily detected during a clinical exam and usually can heal itself — or is surgically repairable — and is thus not typically the cause of long-term hearing loss.

Can hair cells in ear regenerate?

However, in fully mature ears, the capacity for cell division is lost, and hair cell regeneration does not occur. In humans, even a newborn inner ear is fully mature. They found that mature inner-ear cells can be induced to divide.

How do you know if your ears are damaged?

Symptoms may include drainage from the ear, tinnitus, an earache, hearing loss and dizziness. If your eardrum is punctured, the degree by which your hearing is affected depends on the size of the hole in your eardrum and whether the damage leads to an infection or not.

  4. Ringing in your ear (tinnitus)
  5. Spinning sensation (vertigo)
  6. Nausea or vomiting that can result from vertigo.

How does hearing loss affect the brain?

“Brain scans show us that hearing loss may contribute to a faster rate of atrophy in the brain,” Lin says. “Hearing loss also contributes to social isolation. You may not want to be with people as much, and when you are you may not engage in conversation as much. These factors may contribute to dementia.”
