DUCTUS COCHLEARIS Meaning and
Definition
-
The ductus cochlearis, also known as the cochlear duct or scala media, is a vital structure located within the cochlea, a part of the inner ear that is responsible for hearing. It is a fluid-filled tube that runs along the full length of the cochlea and separates the scala tympani from the scala vestibuli. The cochlear duct plays a crucial role in the transmission of sound signals to the brain.
The ductus cochlearis is lined with a specialized sensory epithelium called the organ of Corti, which contains highly sensitive hair cells. These hair cells are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. As sound waves enter the ear, they cause the fluid within the cochlear duct to vibrate, which, in turn, stimulates the hair cells to send electrical impulses to the auditory nerve.
The ductus cochlearis is also home to the endolymph, a fluid that helps maintain the unique chemical environment necessary for optimal hearing. This fluid contains high levels of potassium and low levels of sodium, which are essential for the proper functioning of the hair cells.
In summary, the ductus cochlearis is an integral part of the inner ear that houses the organ of Corti and plays a key role in converting sound vibrations into electrical signals. Without the proper functioning of the ductus cochlearis and the organ of Corti, hearing impairment or deafness can occur.

- "Cochlearis" is a Latin term derived from the Greek word "kokhlias", meaning "snail shell". It refers to the spiraled shape of the cochlea, resembling a snail shell.
Therefore, "Ductus Cochlearis" translates to "cochlear duct" or "spiral-shaped duct" in English, indicating the structure of the inner ear responsible for hearing.
