The __________ turn of the cochlea is located nearest the oval window, and the ___________ turn is at the other end of the coil.

The correct response identifies the anatomy of the cochlea in relation to the oval window. The basal turn of the cochlea is indeed situated nearest the oval window, which is where the stapes, one of the auditory ossicles, transmits sound vibrations. This turn is critical for the initiation of the auditory process. The apical turn, on the other hand, is located at the opposite end of the cochlear spiral, away from the oval window.

Understanding the orientation of these turns is essential for hearing aid specialists, as it relates to how sound energy is converted into neural signals. Proper knowledge of cochlear anatomy can impact how hearing loss is assessed and managed, specifically when fitting hearing aids or considering cochlear implants.

The other options do not accurately describe the relationship between the different turns of the cochlea and their anatomical positions relative to the oval window, leading to confusion about cochlear structure and function.
