The cochlear duct, also known as the scala media, is a vital component of the inner ear responsible for hearing. It's essentially a fluid-filled cavity situated within the cochlea.
Location and Structure
The cochlear duct's position is key to its function. According to the reference, it resides between two other compartments within the cochlea:
- Scala Vestibuli: The upper compartment.
- Scala Tympani: The lower compartment.
The cochlear duct itself is filled with endolymph, a fluid with a unique ionic composition essential for the proper functioning of the sensory cells responsible for detecting sound. The cochlea itself is a part of the inner ear and sits alongside the vestibular apparatus.
