EarsWhether it is the loud bang from an explosion or the calm ticking of the clock, the ears are the organs responsible when it comes to collecting sounds and transmitting signals to the human brain.
This is the function of the ear. The day you stop hearing sounds, you should stop and wonder.
Three sections are what make up the ear anatomy, and these, when put together helps make a person hear. The outer ear, the middle ear and the inner ear work simultaneously to handle sound waves.
The outer ear is called the auricle. The auricle is the visible part of the ear. It has only one job and that is to collect any sounds. The auricle extends to the middle ear, and here ear wax is produced.
Wax protects the ear canal from dirt and ear infection.
The auricle collects sound waves and then it travels to the middle ear. This is where the middle ear has to transform the collected sound waves into vibrations then travel through the eardrum. These vibrations will then reach the cochlea of the inner ear and then convert the vibrations into nerve impulses. The liquid-fill inside the cochlea activates during vibration.
Covered by hair, which is moved during vibrations, creates certain nerve signals and then the brain interprets it.
The ear’s function is not only to hear, but also to hold the body’s balance. The organ that holds balance is found in the inner ear and this is called the vestibular labyrinth.
The structure is looped-shaped and is also found here. Fluids and sensors found in the canals monitor head movement.
Calcium carbonate crystals in the sensors help detect forward and back movement.
The unsteadiness of the body is called vertigo. This causes dizziness. This is basically where the calcium carbonate crystals loosens and then floats.
Certain positions of the head duplicate these nerve endings that relate to balance. The brain receives the wrong signal and then the brain mistakes the movements and it will result in a head spin.
Aging and a huge knock to the head can cause vertigo. Hearing loss is also very common in the lives of elderly people, when they reach a certain age. As people age, slowly do they experience hearing loss, and not in all cases, a few become deaf. However, there is a remedy for those suffering with short hearing and this is called a hearing aid. Hearing aids are designed to suite your individual needs.
