The descending auditory pathway is NOT involved in:
A) modulating the motile response.
B) activating the acoustic reflex.
C) blocking task-irrelevant ascending auditory signals.
D) sending auditory signals from the left ear to the right ear.

Question

Quizplus · Accepted Answer

The descending auditory pathway is primarily involved in modulating the auditory system, such as modulating the motile response of outer hair cells (A), activating the acoustic reflex to protect the ear from loud sounds (B), and blocking or filtering out task-irrelevant sounds (C). It does not send auditory signals from one ear to the other (D); this process involves the ascending auditory pathways and the brain's processing centers, not the descending pathways.
