Verified step by step guidance

Understand the anatomy of the inner ear, which consists of the cochlea, vestibule, and semicircular canals.

Recognize that the cochlea is a spiral-shaped organ responsible for converting sound waves into nerve impulses.

Identify the cochlear duct, also known as the scala media, as a part of the cochlea.

Learn that the cochlear duct is filled with a fluid called endolymph, which is crucial for the proper functioning of the hair cells involved in hearing.

Differentiate between the cochlear duct and other structures such as the semicircular canals, which are involved in balance and also contain endolymph, but are not the primary focus of this question.
