Which statement is true regarding earwax?

Earwax, also known as cerumen, plays a crucial role in the health of the ear. It is produced by glands in the external auditory canal and serves several important functions, including lubrication, protection against dust and bacteria, and maintaining an appropriate pH balance.

The correct statement regarding earwax is that it can affect hearing. Accumulation of earwax can lead to a blockage in the ear canal, which can cause hearing loss or muffled hearing. A buildup of earwax can lead to conditions such as cerumen impaction, where the earwax obstructs the passage and inhibits normal sound waves from reaching the eardrum, thereby affecting auditory perception.

It’s also worth noting that earwax is not a clear liquid; instead, it typically appears as a yellowish or brownish substance. While excessive buildup can lead to complications, earwax itself is not inherently harmful and actually serves protective functions. Additionally, earwax can be produced by individuals of all ages, not exclusively in children.
