Laryngitis Anatomy

To better understand laryngitis, it helps to understand the anatomy of the larynx.

The larynx is part of the upper airway. It begins at the lower pharynx, and extends down to the trachea.

Functions of the larynx include:

  • Maintain an open airway
  • Produce the voice
  • Protect the lungs

The larynx consists of:
  • Epiglottis
  • Vocal cords
  • Subglottic area
  • Thyroid cartilage

Larynx examples:
  • Rear view of larynx
  • Top view of epiglottis with x-ray of enlarged epiglottis
  • Normal pharynx in adult
  • Normal pharynx and epiglottis in child
