Verified step by step guidance

Understand the anatomy of the inner ear, which includes the cochlea, semicircular canals, and vestibule. These structures are part of the membranous labyrinth, which is filled with a fluid called endolymph.

Recognize that the cochlear duct, also known as the scala media, is a part of the cochlea. It is one of the three fluid-filled chambers within the cochlea and is specifically filled with endolymph.

Identify the semicircular canals as part of the vestibular system, which also contains endolymph. However, the question specifically asks for the structure where endolymph is found in relation to the cochlear duct.

Note that the Eustachian tube is not part of the inner ear but rather connects the middle ear to the nasopharynx and is involved in equalizing air pressure. It does not contain endolymph.

Understand that the tympanic cavity is part of the middle ear and contains air, not endolymph. It houses the ossicles (malleus, incus, and stapes) and is involved in sound transmission, not fluid balance.
