Question: 1 / 415

Which anatomical structure is commonly referred to as the voice box?

Trachea

Pharynx

Larynx

The larynx is referred to as the voice box because it contains the vocal cords, which vibrate to produce sound when air is expelled from the lungs. This structure is located in the throat, just above the trachea, and plays a crucial role not only in voice production but also in protecting the airway during swallowing. The larynx allows for the modulation of pitch and volume, contributing to the nuances of human speech.

In contrast, the trachea is the windpipe that conducts air to the lungs, the pharynx serves as a passageway for food and air, and the bronchus refers to the larger air passages that diverge from the trachea into the lungs. While all of these structures are part of the respiratory system, only the larynx is specifically associated with generating voice.
