  • Forming the larynx are nine (9) supportive cartilages, several intrinsic and extrinsic muscles, and a mucous membrane lining.
  • As a primary function, the larynx provides a carefully guarded air passageway (See the GIF below)  between the pharynx and the trachea.

  • During the swallowing process, movements of the cartilages close the entrance to the larynx so food and drink cannot enter.
  • The larynx also houses the vocal folds and ligaments that produce the voice sounds.
