Verified step by step guidance

Understand the structure of the cochlea: The cochlea is a spiral-shaped organ in the inner ear that is responsible for converting sound waves into nerve impulses. It contains the basilar membrane, which plays a crucial role in sound frequency discrimination.

Learn about the basilar membrane: The basilar membrane is a structure within the cochlea that varies in width and stiffness along its length. It is narrower and stiffer at the base and wider and more flexible at the apex.

Recognize the frequency-place mapping: The basilar membrane is organized tonotopically, meaning different frequencies of sound waves stimulate different parts of the membrane. High-frequency sounds stimulate the base, while low-frequency sounds stimulate the apex.

Identify the location for low-frequency sounds: Since low-frequency sounds cause maximum displacement at the apex of the basilar membrane, hair cells in this region are primarily responsible for detecting these sounds.

Conclude the answer: Based on the understanding of the basilar membrane's structure and function, low-frequency sounds stimulate hair cells at the apex of the basilar membrane.
