The Ear and How It Works

Ears and their ears are one of the most important organs of the body. It not only helps to keep balance, but more importantly it gives us the ability to listen. Sound waves are generated when noise occurs. When a sound wave reaches the ear, it passes through three parts of the ear. Ears can pick up sound waves and convert them into nerve impulses that can be read in the brain. Background: Sonic waves are pressure changes in air. Sonic waves travel like air like underwater waves in the air.

First of all, we have to understand the structure of the ears. There are three parts in the outer ear. The ear canal is a conduit through which all sound passes. The eardrum of the eardrum vibrates the ears. The outer ear is elliptical. There is a small bone in the middle ear, and you can pierce the three bones with your ears. There is a cochlea in the inner ear, which includes auditory receptors.

At the end of the ear canal there is a tympanic membrane, or more properly a film called the tympanic membrane. The eardrum separates the outer ear from the middle ear, but here it is regarded as part of the middle ear. Behind the tympanic membrane there is a cavity called the middle ear cavity. There are several structures between the middle ear, the most important of which are the ear canal and the small bone. In addition to the fact that it ventilates through the Eustachian tube, the middle ear space becomes airtight. The ear canal leads from the middle ear to the pharynx (nasopharynx), allowing air to enter and exit the middle ear cavity. This ventilation is used to balance the pressure on both sides of the eardrum. You may touch your ears while on an airplane or on a mountain road. As the altitude rises, atmospheric pressure decreases. This can be painful and leads to a reduction in auditory hypersensitivity

Figure 4. Structure of the ear The outer ear includes the auricle, external ear canal and tympanic membrane. The middle ear includes ossicles and is connected to the pharynx through the ear canal. The inner ear has a cochlea and a vestibule, each responsible for audition and balance. The inner ear consists of a series of tubes embedded in the tibia and is often called a bone maze. There are two separate areas of the cochlea and the front yard, each responsible for hearing and balance. Neural signals from these two regions are transmitted to the brain stem through separate fiber bundles. However, these two different bundles move from the inner ear to the brain stem as the vestibular cochlear nerve. The sound is converted into a nerve signal in the cochlear region of the inner ear. It contains sensory neurons of the spiral ganglion
