The ear consists of three parts: external, middle and inner ear.
Almost every part of the outer ear is visible, such as: ear sink, an external bowel hole and a blanket of the mouth that is exposed to the middle ear from the outer ear. The table is followed by the middle ear – a small hollow, which consists of three small bones adjacent to each other (one after another). From the bones of the first (hammer) is attached to the apple cuff, the last (mouthpiece) – the oval window thin apk, which is the middle ear allocated from the inner ear.
Ear-anatomy is the smallest and most important part of the ear ear. It is involved in hearing body (lokokina) and equilibrium body, or vestibular apparatus. In the equilibrium body cells are placed, which react to changes in body space and transmit the brain information about this metabolism. Due to the fact that hearing and equilibrium are located side by side, children with hearing loss often have a violation of the equilibrium and motion.
The listening body is called “lokkina”, because its shape resembles the lokkini shells. The lokokina is filled with fluid, it has a special plate on hearing receptors – lumbar cells. They respond to different frequency sounds (different sound tone) and join the hearing nerve, which gives the sound information to the center of the center.
Sounds and speech analysis is underway in the cerebral and cortical centers of the brain.
Ear-anatomy ear, hearing nerve, cerebral cortex and cortical hearing centers together with the hearing system.
The cervical centers are analyzed in the localization of sound, the unintentional reaction on the sounds and the other. Basic processes of analysis, understanding, remembering, speech and environmental sounds are maintained and understood in the large hemisphere of the brain.
Cortical centers are listening to the zones of the large hemisphere of the brain. Hearing areas are located in the highest parts of the brain. They are associated with brain movement, sight and other centers. Because of this, when we hear the dog’s throat, the picture of the dog is shown immediately and we can repeat this sound or say the word “dog”.
The man has two ear and the cervical and cervical hearing center of the brain is also paired. At the same time, they join each other and interact. Two ear interactions are called a flat hearing. They are necessary to determine where the sound is coming and the sounds and sounds in the noise and in the buildings where the sounds are strongly reflected from the wall (reverbation).
In the analysis of speech with the right, the main role of the brain left hemisphere. 70% of the Left’s also characterized the active participation of the left hemisphere in speech perception. The remaining hemisphere is dominated by the right hemisphere or both hemisphere plays an equal role. The right hemisphere of the brain participates in speech analysis, for example, in an analysis analysis, in speech noise perception. In addition, the right hemisphere plays a role in the child’s speech. In the left half of the information comes mainly from the right ear and in the right hemisphere – from the left ear. The hemispheres are interacting with one another in the processing of information through special structures that form the hemispheres.
