The structural change with aging that is most associated with hearing loss takes place in:
A) the pinna.
B) the cochlea.
C) the stapes.
D) the middle ear.

Question

Quizplus · Accepted Answer

The cochlea is the portion of the inner ear responsible for detecting sound vibrations and converting them into neural signals that can be interpreted by the brain. With aging, the cochlea undergoes structural changes including the loss of sensory hair cells, which are essential for hearing. This is the most significant structural change associated with age-related hearing loss, also known as presbycusis. The pinna and stapes are both parts of the outer and middle ear, respectively, and are not directly involved in detecting or converting sound vibrations.
