Meaning and Definition
A fluid-filled membranous tube within the cochlea of the inner ear that contains the organ of Corti, the sensory organ for hearing.
Often used as a synonym for 'scala media' in anatomical terminology. It represents the specific functional compartment where auditory transduction from sound vibrations to nerve impulses primarily occurs.

FAQ
Frequently Asked Questions
No. The cochlea is the entire spiral-shaped bony structure of the inner ear. The cochlear duct (scala media) is one of three fluid-filled tubes running along the inside of the cochlea.
It is filled with a fluid called endolymph, which has a high potassium concentration, crucial for generating the electrical potential that drives auditory signal transduction.
Yes. Since the cochlear duct contains the organ of Corti (the sensory epithelium with hair cells), damage to this structure typically causes permanent sensorineural hearing loss.
You would only encounter it in specialised contexts: medical school (especially anatomy and otolaryngology), audiology training, neuroscience research, and advanced biology or physiology textbooks.
