Question

Which of the following is sound producing organ in man ?

• A. Pharynx
• B. Larynx
• C. Trachea
• D. Bronchus

Answer 1

The Correct Option is B

To solve the problem, we need to identify the sound-producing organ in humans.

1. Understanding the Human Respiratory and Vocal System:
The human respiratory system is responsible for breathing, while the vocal system allows us to produce sounds and speech. The key structures involved in sound production are located within the larynx.

2. Role of Each Option:

• (A) Pharynx: The pharynx is a muscular tube that serves as a common passageway for both air (respiration) and food (digestion). While it plays a role in modifying sound during speech, it is not the primary sound-producing organ.
• (B) Larynx: The larynx, also known as the voice box, is the primary sound-producing organ in humans. It contains the vocal folds (or vocal cords), which vibrate when air passes through them, producing sound. The larynx is crucial for speech and singing.
• (B) Trachea: The trachea, or windpipe, is a tube that connects the larynx to the bronchi. It primarily functions as a passageway for air but does not directly produce sound.
• (D) Bronchus: The bronchi are branches of the trachea that lead into the lungs. They are part of the respiratory system and do not play a role in sound production.

3. Identifying the Correct Answer:
The sound-producing organ in humans is the larynx, as it houses the vocal folds responsible for generating sound.

4. Conclusion:
The correct answer is (B) Larynx.
