Practice question

Go with B — Detect sound. Within Sensory System Ear Physiology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, the functional job described in the stem is exactly what Detect sound does in Sensory System Ear Physiology. Holding that picture in mind makes Detect sound feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Detect sound.
