Describe the type of energy that is traduced at each anatomical landmark of the ear (outer ear, middle ear, inner ear). 

 

The ear translates acoustic energy.

The sense of hearing is fundamental for the human development of the individual in society, being one of the primary senses for our species.

One of the main functions is to convert sound waves into vibrations that stimulate nerve cells, for this the ear has three interconnected divisions: outer, middle and inner ear. Each part has specific functions within the sound processing sequence

The external part is the visible part, the ear and the auditory canal, which functions as a kind of receiver-receiver and conducts the vibrations (sounds) to the middle ear.

The eardrum divides the outer ear from the middle. There the sound waves (sounds) are converted into mechanical energy (vibrations).

The middle ear begins with the eardrum, which is a thin and sophisticated pearly gray membrane, which, as we said, vibrates with every sound that comes through the outer ear. The eardrum transmits the vibrations to the ossicles known as "auditory ossicles", the 3 smallest bones in the human body.

In the inner ear, vibrations are sent from the ossicles of the middle ear to the cochlea or snail (inner ear), a kind of liquid-filled labyrinth where the true hearing organs reside (Organ of Corti). In the inner ear, mechanical energy is converted into electrical impulses, which are sent to the brain through the auditory nerve.

The most important auditory and sensory organ is the organ of Corti. This is part of the cochlea and contains between 15,000 and 20,000 specialized sensory cells that pick up the vibrations sent to the fluid or cochlear fluid. These cells, similar to tiny hair, pick up different frequencies in vibrations and send them to the brain as electrical energy. Once in the brain, various decoding processes occur in which many other factors come into play, for example speech and understanding of sound that produces the understanding of what is heard and will provoke a reaction depending on which one, one of the The main examples are language, we listen to words, we process them and we can give a verbal response with another sound.
