ไม่โกรธ แต่ไม่ลืมthe sense of hearing is accomplished by a process known as auditory transaction. The you convert sound waves in the air into electrical impulses which can be interpreted by the brain. ascendant receive your it passes through the external auditory canal where it meets the tympanic membrane the tympanic membrane then vibrates in response to the sound sounds a bit lower pitch of frequency produce a superior to vibration and sounds of lower volume or amplitude produce a less dramatic fabrication higher frequency sounds produce faster vibrations per nick membrane is coming shaped and articulates with the chain three bones called the auditory ossicles they consist of the malleus Inc.’s and the state fees the movements of the tympanic membrane 5 repins passing on the information frequency handled the tree bones to fit together on an axis shown here in red the pivotal axes is due to a series of ligaments which hold the bones in place within the middle ear cavity the interior the ligament and the pope to you in cute ligament of particular importance for the pivotal axis two structures which normally obscure this few the middle ear have been removed they are the court date in containers and the tendon the tensor tympani muscle through the ossicles the vibrations of the tympanic membrane are transferred to the footplate the state fees the state these moves for the pistons like an engine which sends vibrations into structure company labyrinth
Labyrinth is filled with a fluid called parent
If it were completely closed and inflexible system the movement to the state fees would be unable to displace the parents and therefore unable to send vibrations into the tony structure due to the flexibility of the membrane called the round window the staves movement can displace the Paralympic allowing vibration to enter the labyrinth
The quarter leading to the round window id found with inspiring portion of the bony labyrinth known as the cochlea fiber by the state these are dawn into the Sperry system and returned to meet the round window the portion at the spa operations ascends to the apex at the complete is called the scales a vestibule into the passage is called the scale attempt any
A third straight churn called the cochlear duct is situated between Scylla steadily in a skillet empty the cochlear duct is filled with a fluid called into them and when viewed in cross-section the membrane separating the two-fluid-filled systems are visible they are race national brain and the basal membrane the membrane are flexible and move in response to the vibrations traveling at the skillet stupidly the movement of the membrane then sent vibrations back down to the skillet Anthony
A specialist structure called the corgi is situated in the basal membrane as the basal membrane vibrates you’re going to score tea is simulated which since nerve impulses to the brain via the conclusion urns
Pluses are generated by specialized cells within the organic forty called hair cells the hair cells are closely covered by structure called the tech to membrane
As the basal membrane vibrates the tiny clusters have hairs are bent against the tech to remembering trigger the hair cells to fire
The inter empress does on vibrate simultaneously instead areas along the basal membrane variably in response to difference frequencies of sound lower frequencies fiber the business remembering closer to the apex at the complete whereas higher frequencies produce vibrations closer to the base this is known as a new topic organization
Together this sequence of event is responsible for our acoustic perception the world around us
