What is the larynx?

The larynx is an organ at the front of your neck. It is also called the voice box. It is about 2 inches long and 2 inches wide. It is above the windpipe (trachea). Below and behind the larynx is the esophagus.

The larynx has two bands of muscle that form the vocal cords. The cartilage at the front of the larynx is sometimes called the Adam's apple.

The larynx has three main parts:

• The top part of the larynx is the supraglottis.
• The glottis is in the middle. Your vocal cords are in the glottis.
• The subglottis is at the bottom. The subglottis connects to the windpipe.

The larynx plays a role in breathing, swallowing, and talking. The larynx acts like a valve over the windpipe. The valve opens and closes to allow breathing, swallowing, and speaking:

• Breathing: When you breathe, the vocal cords relax and open. When you hold your breath, the vocal cords shut tightly.
• Swallowing: The larynx protects the windpipe. When you swallow, a flap called the epiglottis covers the opening of your larynx to keep food out of your lungs. The food passes through the esophagus on its way from your mouth to your stomach.
• Talking: The larynx produces the sound of your voice. When you talk, your vocal cords tighten and move closer together. Air from your lungs is forced between them and makes them vibrate. This makes the sound of your voice. Your tongue, lips, and teeth form this sound into words.
