What is Utricle?
Utricle is one of the two otolite organs inside the ear canal, the other is a saccule. Otolites organs are able to capture gravitational changes and linear acceleration that come from movement in a straight line. Utriculus, which is also called Utriculus, is occupied by the bony labyrinth of the inner ear, set between the cochle and the semicircular channels.
Otolithic organs detect movement depending on their orientation. Animals or people without otolites are unbalanced. Utricle detects movement on the horizontal plane of the head and saccule detects vertical movement. These hair cells are associated with the nervous system of vestibular dividing fibers of the auditory nerve, each hair cell associated with one fiber. As stones accelerate from movement, strength develops on the hair cell. When the hair cell cells detect the force of moving stones, the signal is sent to the brain by a vestibular nerve that warns the brain that movement occurs.
otolithic organs are subject to gravity, and since gravity always pulls otolites towards the ground, the change in orientation changes the direction in which the otolites stretch. This causes another stimulus to hair cells, which then send different nerve pulses to the brain. This is why Utrice is constantly reporting the head orientation. Information that is sent from Utricle to the brain also indicates the overall position of the whole body when working in conjunction with muscle information. Therefore, he is also able to determine this exact position in the space of each part of his body.
Some health conditions may damage Utricle and cause imbalances of the affected persons. These disorders may come from damage to the ear canal, peripheral or brain disruption, psychiatric disorders and cortical vestibular disorders. Problems may also occur in some diseases such as Menieres, acoustic neuroma, strokes and seizures that include vestibular bark.
Menieres illness affects as saccule, the oneto suffer, causing the wall of saccule to be much thinner than the suffricular wall. When this happens, the saccule grows larger than Utricle, causing the loss of Utricle. The acoustic neurom will disconnect from the brain that disrupts the nerve pulses sent by the Utricle during movement. When a person suffers from a stroke involving the vestibular bark, it may seem that the world turns upside down and may suffer from several forms of illusions of inversions that seem to lean the visual axis.
