AQUEDUCT OF COCHLEA Meaning and
Definition
-
The term "Aqueduct of cochlea" refers to a small, spiral-shaped canal located within the inner ear. The cochlea is a vital part of the auditory system responsible for receiving sound vibrations and transmitting them to the brain for interpretation. The aqueduct of cochlea, also known as the cochlear aqueduct, is a narrow, fluid-filled passageway that exits the cochlea and connects it to the subarachnoid space surrounding the brain.
The primary function of the aqueduct of cochlea is to allow for the exchange of fluids and pressure regulation within the cochlea. It acts as a channel through which perilymph, the fluid found inside the cochlea, can flow in and out of the inner ear, maintaining its equilibrium. This fluid exchange ensures that the delicate structures inside the cochlea remain protected and functioning optimally.
The aqueduct of cochlea is of great significance in the field of otology as its size, shape, and functionality play a role in various auditory disorders. Its abnormal enlargement can result in the leakage of perilymph, leading to a condition called perilymphatic fistula. Moreover, blockage or narrowing of the aqueduct can disrupt the normal flow of fluid, potentially causing hearing loss or other related symptoms.
In summary, the aqueduct of cochlea is a vital anatomical structure responsible for maintaining fluid homeostasis within the cochlea. Its proper functioning is crucial for preserving normal hearing abilities and preventing the onset of auditory disorders.
