Larynx: anatomy, location and function
Several ligaments and membranes loosely hold the cartilages together.
Two sets of muscles control larynx movements.
- Intrinsic muscles regulate the tension and orientation of the vocal ligaments that produce the voice. Superior view/ Lateral view
- Extrinsic muscles (not shown) adjust the position of the larynx during the swallowing process.

Respiratory mucosa (or mucous membrane) covers most of the interior surface of the larynx. It is continuous with the tissues that line the pharynx and serves to further clean, moisten and warm inhaled air.
Location and Functions of the Larynx
- 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.
