What are the hair cells in the ear called?

The inner ear is shaped like a snail and is also called the cochlea. Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that sound is.

Also asked, can ear hair cells repair themselves?

After a songbird loses its hearing due to physical trauma or loud noise, the sensory hair cells in its inner ear regenerate naturally. The healed bird can use its restored hearing to decode complex songs from other birds. In fact, this ear repair is almost universal in vertebrates.

Can ear hair cells grow back?

Hear This: Scientists Regrow Sound-Sensing Cells. Scientists have coaxed sound-sensing cells in the ear, called "hair cells," to grow from stem cells. Human hair cells do not naturally regenerate; so as they die, hearing declines.

What is the purpose of the hair cells in the inner ear?

There are two types of hair cells in the organ of Corti, the inner and outer hair cells. The outer hair cells (OHC) perform an amplifying role and it is the inner hair cells (IHC) that detect the sound and transmit it to the brain via the auditory nerve.
