Cerumen, commnly called as earwax is a yellowish, waxy substance secreted in the ear canals.


It is produced in the outer third of the cartilaginous portion of the ear canal.

Earwax consists of shed skin cells, hair, and the secretions of the cerumenous and sebaceous glands as well as from modified apocrine sweat glands of the outside ear canal. It plays an important role in the human ear canal, assisting in cleaning and lubrication. It also provides some protection from bacteria, fungi and insects.
