What creates ear wax?

Published in Ear Physiology 2 mins read

Ear wax, also known as cerumen, is produced by specific glands within the ear canal.

The Anatomy of Ear Wax Production

The ear canal, a crucial part of the external ear, isn't just an empty tunnel. It's lined with:

  • Hair follicles: These are small structures from which hairs grow.
  • Glands: These specialized structures are responsible for the production of ear wax.

These glands secrete a waxy, oily substance called cerumen, which serves multiple important functions.

Cerumen Production

Cerumen is not just random secretion; it's the result of the activity of specialized glands. These glands are designed to protect the ear canal. Here's how:

  • Protective Coating: Cerumen creates a protective layer inside the ear canal.
  • Trapping Foreign Particles: This waxy coating helps trap dust, dirt, and other foreign particles.
  • Lubrication: Cerumen helps keep the skin of the ear canal lubricated and prevents it from drying out.
  • Antibacterial Properties: It contains chemicals that inhibit the growth of some bacteria and fungi.

What Happens When There's Too Much?

While the ear has its own way of clearing out the ear wax, sometimes these glands produce more than the ear can handle. This can lead to:

  • Excessive Wax: The glands sometimes produce an overabundance of wax.
  • Hardened Wax: Excess wax can harden within the ear canal.
  • Ear Blockage: The hardened wax can cause a blockage in the ear canal which may reduce hearing ability.

Functions of Ear Wax

Function Description
Protection Traps dust, dirt, and other foreign particles, preventing them from entering the ear.
Lubrication Keeps the skin of the ear canal moist and prevents it from drying out.
Antibacterial Contains substances that protect against bacteria and fungi.

Therefore, cerumen is not just a byproduct; it is a complex secretion that plays a key role in keeping the ear healthy and functioning correctly.
