How do we hear? What are the parts of the ear with photos?

Here are the judgments with photos under the protection of hearing parts. The judgments may seem relatively simple, but in reality it is only part of the complex hearing system consisting of: channels, vibration structures, nerves and specialized areas in the brain that work together to collect and interpret sound. For people with a natural audience, the ears can whisper a child, thunder noise, orbird -tweets or the whole group of machines in the orchestra. Look at the auditory system structures and discover how to give the votes around you about the judgments with photos? Three parts of the ear are three parts: the outer ear. The middle ear. Inside -over. Every part of components that play clear roles in the process of turning sound waves into signals goes to the brain. The outer over the outer judgments consist of the visible part of the ear, the gaze, the ear canal and the earrum. The gaze is in the form of a cup and collects sound waves from the ocean and directs them within the ear canal, when the sound wave hits the drumbling to a certain extent. The middle ear is a cavity full of air, with a series of three legs: hammer, anvil and passengers. The middle ear is opened to the rear of the nose and the upper part of the throat through a narrow channel, the audience or nail tube, opened the tube and closed at the end of the throat to repair the air in the middle ear, the exit of fluids and the budget of the over -budget, as the pressure equal to both sides of the ordin. The media bones of the middle ear contain three small bones, namely: the hammer: linked to the eardrum. Anvil: which is located in the middle of a series of legs. Passengers: Linked to the oval frame covered with an open membrane of the inner ear. The vibration of the drum flies causes a series of vibrations through the bones. Due to the differences in the shape, size and status of the three bones, the strength of vibration increases as it reaches the inner ear. This increase in strength is needed to transfer the energy of the sound wave to the fluid in the inner ear. The inner ear contains a group of cochlea full -fold rooms, there is a snail -shaped room called the shell, and plays a role in the hearing process, where sound vibrations of the middle ear bones are transferred to fluids in the cochlea, and small sensors whose cochlea conversions are transferred vibrations into electrical flashes. Other rooms are filled with liquid in the inner ear and contain three tubes called sickle channels, and hair cells in the sickle channels reveal the movement of fluid as they move in any direction, and convert the movement into electrical signals sent to the brain. As you move to the brain, electrical signals are transferred next to the audience nerve by various information processing centers, and signals are transferred from the right ear to the audience shell located in the temporal lobe on the left of the brain, while the signals are transferred from the left ear to the audience crust to the right of the brain. These types of hearing scale processes, interpretation, audio information, the comparison and analysis of all signals that reach the brain, and enable you to detect sounds and suppress other noises of noise in the background.
