Channel Awstaki Eustachian tube

Channel Awstaki Eustachian tube:A channel that extends from the middle ear to the nasopharynx and length of each side Juala 35 centimeters in an adult human, and a third near the middle ear component of bone either the remaining two thirds understanding components of cartilage. It extends from the front wall of the middle ear to the nasopharynx (ie, the throat behind the nose area or vacuum behind the nose) and here are a prominent channel fold.Related muscles are:levator palatitensor veli palatinisalpingopharyngeusAnd feeds these muscles and ten cranial nerve fifth cranial nerve.
Line the mucous membrane channel such as the lining of the middle ear.
What is the work Channel Awstaki:

Interest of this channel is to equalize the pressure on both sides of eardrum thereby protecting it eardrum that hurt from the change of pressure on either side: For example, if I went up to Mount Van air pressure will be low, which makes eardrum strained out, if swallowed Rivk the muscle tensor veli palatini shrink and allow air to escape from the middle ear, which is equivalent to pressing the eardrum due to its natural form, and sometimes we hear his voice like Snap, a return to its first position. If I got out of the mountain, the air will enter the new.Unfortunately the channel would allow the exit of the air more than they allow entering into the middle ear, as if you, for example, infected with a cold van channel Sttorm and will decrease the air inside and outside through. In ascension will be able to balance the pressure In Nzulk the air can not enter: we may feel pain in your ear and sometimes to the extent of ruptured eardrum.
And also is working to drain mucous secretions so the clogged as a result of the sensitivity of bacterial infection or Vairose will lead to accumulation of mucous secretions and multiplication of bacteria which leads to inflammation of the ear.
In children are more horizontal channel and narrower than adults so they get ear problems more than adults.
Cells in the mucous membrane her Hdibat so move mucous secretions, but if a person smoked cigarettes Van these Ahudabat work will be slow, leading to the accumulation of mucous secretions and ear infections.




Pay attention to this film
