The body is amazing, and the way we live our lives, shows a lot through our body, because our souls reflect the experience of lives, through our eyes and the shape, forms and imperfections we have.
In today’s article we are going to talk about, the part of the body, which allows us to hear the sound waves, which travel the air space.
We are going to talk about the ear, regarding deafness, which is very common in our current society.
First though, let’s understand what the ear consist of, the ear has three major areas, the outer ear, the middle ear and the inner ear.
A person hears when sound waves, pass through the outer ear and cause vibrations at the eardrum.
As the sound waves travel to the inner ear, the eardrum and three small bones of the middle ear, amplify the vibrations.
The vibrations also pass though the cochlea, which is the snail-shaped structure located in the ear, and it is filled with fluid.
Thousands of tiny hairs, which help translate sound vibrations, into electrical signals, which are then transmitted to the brain, are attached to nerve cells, in the cochlea.
The tiny hairs are affected by the vibration of different sounds, in different ways; nerve cells can then send signals to the brain, through this process; allowing a person to distinguish one sound from the other.
The body is truly an amazing peace of work, and we should learn more about it, to be able to appreciate what we have.
When sound signals cannot reach the brain, then many people experience, something known as hearing loss.
The two main types of hearing loss, are: sensorineural hearing loss and conductive hearing loss; a person would develop, either one of these based on the where the problem is found.
When the sensitive hair cells inside the inner ear or the auditory nerve, is damage, then this is known as sensorineural hearing loss.
Many people develop sensorineural hearing loss, naturally with age and other people develop, this type of hearing loss as a result of an injury.
As a person ages, that person would naturally lose the tiny hair cells, connected to the cochlea, according to scientific findings.
The way a person takes care of their body also, such as how they eat and exercise, have something to do, with them losing these tiny hair cells, over time as well.
Repeated exposure to loud noises, can cause a person to suffer from sensorineural hearing loss, over time.
People with diabetes, cardio vascular problems, meningitis, acoustic neuroma, Ménière's disease, encephalitis, multiple sclerosis, as well as viral infection of the inner ear and the auditory nerve, head injury, malformation of the ear and a stroke; are more prone to suffer from sensorineural hearing loss.
Conductive hearing loss usually happens through ear wax or glue ear, build up and blockage, over time.
A person with an ear infection, can also develop conductive hearing loss; also conductive hearing loss may happen though a perforated eardrum, otosclerosis, damage to the hearing bones from injury, conditions such as cholesteatoma, collapsed ear drums, malformation of the ear and swelling around the Eustachian tube, which is cause by jaw surgery or radiotherapy for nasal or sinus cancer.
