What are hair cells?

In biology, hair cells are part of the ear. Scientists call them hair cells because of their furry appearance at the microscopic level. The function of cells is to perceive noise, which are actually air disorders called Sound Waves. When the sound passes into the ear, the hairy cells are circling in response to the air movement and transmit electrical signals from their movement to the nerves that transmit the sound to the brain to interpret.

The ear has three main parts. The outer ear includes an outer ear that helps the sound waves to pass into the middle ear. The middle ear contains an ear drum that receives sound waves, and passes vibrations to the bones of the middle ear, which in turn vibrate. These vibrations represent environmental sound waves on the inner ear.

inside the inner ear, located on the inside of the ear drum, are smaller pieces of auditory equipment. The main component is Kochlea and Kochlea includes organ Conti. The Conti is inside Kochle and consists of many hair cells.The cells on the side closest to the outer ear are called outer hair cells and the cells are inside the internal hair cells.

All these cells have what the hair seems to be at the upper end of the cell. The lower part of the cells is glued to the membrane called the basil membrane. Hair results protruding from the top of the cells are actually cell extensions and are technically known as stereocilia. Above the line of hair cells in the CONTI organ there is a membrane called the tectorial membrane and the hairy parts of the cells touch this membrane.

Sound waves enter Kochlea into the inner ear and cause vibrations in the basillary membrane. This is circled by stereocilia on the cells and the cells themselves are also circling. The twisting movement causes a cell to produce an electrical impulse, which concerns the sound, and because the nerve cells are located under the cells, this pulse moves into the nerve cells. Nerve cells then pass afterThe sound of sound into the brain and the brain interprets the type and intensity of the sound.

Hair cells may respond less to sounds if they are damaged. Loud sounds are able to damage cells because the hairy parts of the cell bend too much and cannot restore their original ability to move in response to sounds, almost the same way as the strong wind can bend the trees, so it loses its flexibility. Research has shown that some animals such as birds can grow new hair cells and thus improve damaged hearing, but people naturally do not correct these cells if they are damaged, and hearing loss is irreparable until experimental treatment proves otherwise.
