What does the term cerumen refer to?

Cerumen refers to ear wax, which is a natural substance produced by glands in the ear canal. Its primary function is to protect the ear by trapping dust, microorganisms, and other foreign particles, preventing them from reaching the inner parts of the ear. Additionally, cerumen helps to lubricate the ear canal, maintaining skin integrity and preventing dryness. Understanding the term is important in a medical context, particularly regarding ear hygiene and health, as excess cerumen can lead to blockages or hearing issues. The other options do not pertain to cerumen; eye drops are related to the eyes, nasal mucus concerns the nasal passages, and medical adhesive is a material used in various medical applications unrelated to ear health.
