WebThe Spiral Organ contains several distinct structures, each with a specific anatomy and physiology, that work together to transduce sound waves into electrical signals that can be interpreted by the brain. • Endolymph of cochlear duct: The cochlear duct contains a fluid called endolymph, which is rich in potassium ions.
